Test Equipment[edit]

The test equipment configuration contains a list of all the test equipment used during a test. The software uses this list to determine which device drivers should be used to control the test equipment. RadiMation^® allows you to configure specific test equipment lists for each type of test as well as different test equipment lists for the same type of tests. (This can be useful if you have, for example, more than one signal generator to perform conducted immunity tests with).

In the 'Test Equipment' window a set of test equipment will be selected. When a calibration file is generated, RadiMation^® will record this test equipment configuration together with the calibration data. When a substitution test is started, the test equipment selected for the substitution test will be compared with the test equipment used (as recorded) during the calibration test. If the equipment does not match, an error message will be displayed.

The error message window will ask you to abort the test or to ignore the error message and continue the test with different test equipment. To achieve maximum accuracy, the same test equipment should be used (whenever possible) during both the calibration and the substitution tests.

To add, modify or delete test equipment lists, go to the 'Test Equipment' window in the 'Configuration' tab.

The 'Test Equipment' window will open and show the current configured list of test equipment. To leave the 'Test Equipment' window, click 'Close' .

Adding test equipment[edit]

To add a (set of) test equipment to the configuration, click the 'Add' button in the top of the window. The 'New Test Equipment' window will appear.

Enter a name for the new test equipment in the 'New Test Equipment' window (e.g. Example Test Equipment).

Click 'OK' to confirm the name of the new test equipment, or click 'Cancel' to cancel the new name. You will be returned to the 'Test Equipment' window.

Before Action[edit]

Under the tab 'Before Action' any and all actions that the end-user wants to have carried out before the equipment of the selected 'test equipment' is initialized can be specified.

'Before actions' can be used to:

Turn on a manual controlled amplifier.
Manually change antenna height or polarization.
Connect cables or create a specific measurement setup.

(It is also possible to specify actions that should be carried out after the equipment of the selected Test Equipment is disabled. This functionality is called 'After Action'.)

The easiest way to explain this function is with an example:

Example[edit]

RadiMation^® needs to be configured for people who do not perform EMC measurements every day. To make sure the engineers do not forget to use the right equipment and procedure, the manager has decided to incorporate a reminder in the test setup.

This is done by adding a message in the 'Before Action' configuration:

1. Open the 'Test Equipment' window, select the desired test equipment set and open the 'Before Action' tab.

2. Press the 'Add' button at the bottom left of the 'Before Action' tab to open the 'Add Action' window.

3. Select the 'Messagebox' option and click 'OK' (or double click on the 'Messagebox' option). A dedicated window will appear.

4. Configuring the desired text in the 'Messagebox Configuration' window and click 'OK' . You will be returned to the 'Test Equipment' window.

The message has now been added to the configuration. As a result, RadiMation^® will prompt the following message before the test equipment is initialized:

After Action[edit]

Under the tab 'After Action' any and all actions that the end-user wants to have carried out after the equipment of the selected 'test equipment' is disabled can be specified.

'After actions' can be used to:

Manually turn off the amplifier.
Play a Wav file (as an auditory signal) to alert the user that the measurement is done.

(It is also possible to specify actions that should be carried out before the equipment of the selected Test Equipment is initialized. This functionality is called 'Before Action'.)

Default address information[edit]

When you make a new EUT file the name and address information of the producer, test house and client can be entered separately.

In many situations one or more of this information will be the same for different EUT files (i.e.: when a test house owns the software, the test house data will always be the same).

To prevent users from having to enter repetitive data input, RadiMation^® provides the option to set default address information for:

The default client
The default manufacturer
The default test site

Data entered under 'Default Address Information' , will automatically be entered in the EUT window and therefore only needs to be entered once.

To add, modify or delete the default address information, go to the 'Default Address Information' window in the 'Configuration' tab.

Enter the desired information as shown in the example below.

To confirm the data input, click 'OK' , to cancel the data input, click 'Cancel' . The 'Default Address Information' window will close.

Advanced options[edit]

There are a several advanced options in RadiMation^®, that allow to tune or optimize some specific settings. Making changes to one or more of those settings, can have a major influence in the correct functioning of the software. Changes to one or more of these advanced options are only needed to circumvent a specific situation. Before changes can be made, a specific password should be specified. The required password is not related to any of the passwords of existing engineers. If it is necessary to make a change to one or more of the advanced options, the password will be provided to the end-user by the reseller or DARE!! Instruments. If the password is specified correctly, a configuration window is shown that includes a table to review and edit the list of advanced options.

Configuration[edit]

RadiMation^® allows the user to define an extensive default configuration. This includes the settings for the:

Units
Directories
Device Drivers
Graphs
Database
Language
Measurement settings
Product standards
Basic standards
Enhanced Status Window

To configure these settings, go to the 'Configuration' window in the 'Configuration' tab.

1. Unit configuration[edit]

The default settings for the different units can be set in the 'Units' tab. These units are used throughout the software package and can be changed at any time during measurements and viewing.

It is possible to define different units for different tests. The following can be selected:

Radiated Immunity
Conducted Immunity
Radiated Emission
Conducted Emission
Pulsed Immunity

Changing unit settings[edit]

To change the settings of a unit, choose the desired test (e.g. Radiated Immunity) from the drop down menu in the 'Units' tab.

Select the measurement (e.g. Power) and click 'Change' .

The 'Unit configuration' window will appear, allowing you to change the parameters of the unit.

To confirm your changes, click 'OK' , to cancel your changes, click 'Cancel' . You will be returned to the 'Configuration' window.

Click 'Close' to leave the 'Configuration' window.

2. Directory configuration[edit]

The RadiMation^® software can use different directories to store different data file types.

The location of the following file types can be specified:

Equipment Under Test Data files (*.EUT files),
Correction files (*.COR files)
Calibration files (*.CAL files),
Configuration files (*.TSF files),
Sequence files (*.SEQ files),
Limit line files (*.LLF files).
Printout files (*.DOC files).

The different file types are described in Chapter 18 “RadiMation^® file types and locations”.

For each data type the default location can be entered through the configuration. The path name can link to a directory on a local or network drive.

Selecting a network drive will allow you to store data (e.g. EUT data) on a computer network, making it more accessible.

Modifying a path name[edit]

To modify a path name, go to the 'Configuration' window in the 'Configuration' tab.

Go to the 'Directories' tab, select the directory that you wish to change and click 'Change' .

The 'Browse For Folder' window will appear, allowing you to select (or make) a new folder in your directory.

To confirm your change, click 'OK' , to cancel your change, click 'Cancel' . You will be returned to the 'Configuration' window.

Click 'Close' to leave the 'Configuration' window.

3. Device Driver configuration[edit]

Device drivers let your software know which equipment has to be used and controlled during EMC tests. In RadiMation^®, these device drivers only need to be configured to the customer requirements once. During the configuration of the device driver, information such as the IEEE address or RS232 COM-port has to be entered.

You can configure the device drivers in the 'Device Drivers' tab of the 'Configuration' window.

This window can be accessed in one of two ways:

1. Through the 'Configuration' tab.

2. Through the 'Devices' tab.

Select a device driver type[edit]

The first step to create or configure a device driver is to select the required 'Device Driver Type' (e.g. Signal Generator). This can be done from the drop-down menu in the ‘Configuration’ window. One’s a type has been selected, the available drivers for that type will be shown.

Adding a new device driver[edit]

To create a new RadiMation^® device driver, select the desired 'Device Driver Type' (e.g. Signal Generator) and click 'Add' . A dedicated window will appear.

Select a new device driver (in the scroll menu or through the search function) in the new window and click 'New' . The 'Device Driver Configuration' will appear.

To cancel your selection and return to the 'Configuration' window, click 'Close' .

In the 'Device Driver Configuration' window the name/description of the chosen device driver can be changed.

To confirm your changes (or the provided description), click 'OK' , the 'Device Driver Settings' window will appear. This window will allow you to edit the information on this device driver. More information about editing device driver settings (and this window) is available further below.

To cancel your changes, click 'Cancel' . You will be returned to the previous window (e.g. New Signal generators).

Editing a device driver[edit]

To edit an existing device driver, select the desired (device driver) type and device driver, then click 'Edit' . The 'Device Driver Settings' window will appear. More information about this window is available further below.

Removing a device driver[edit]

To remove an existing device driver, select the desired (device driver) type and device driver, then click 'Remove' .

A confirmation window will appear. To remove the selected device driver, click 'Yes' , to cancel, click 'No' . You will be returned to the 'Configuration' window.

Device Driver Settings[edit]

The 'Device Driver Settings' window contains information on the selected device driver. In this window the generic settings for that driver can be added, edited and removed.

Confirm settings[edit]

To confirm the (current/new) settings, click 'OK' . To cancel changes made during editing, click 'Cancel' . You will be returned to the 'Configuration' window.

Fixed information[edit]

The 'Device Driver Settings' window contains a minimum list of 'fixed information'. Although these settings cannot be removed, part of their information can be altered. These settings include:

Brand

Shows the brand of the device. This information can be changed/viewed in this cell and can be used in the report generator.

Description

Shows the description of the device. This information can be changed/viewed in this cell and can be used in the report generator. Changing the description does not result in losing the device in the test sites. The description is automatically updated in the test site information. If a report is generated from a test done prior to the description change the old description will be inserted.

Device driver DLL Version

Shows the exact version of the DLL in which the device driver is contained. This is a unique identifier that specifies the version of the device driver. The contents of this cell cannot be changed. (More information on this data cell is explained further below in the paragraph ‘Storing the driver version in the test file’.)

Device drivers installation date

Shows the date and time of the last update/installation of the device drivers. The contents of this cell cannot be changed. (More information on this data cell is explained further below in the paragraph ‘Storing the driver version in the test file’.)

Device drivers versions

Shows the version number of the last update/installation of the device drivers. The contents of this cell cannot be changed. (More information on this data cell is explained further below in the paragraph ‘Storing the driver version in the test file’.)

Hardware version

Shows the hardware version of the device. This information can be changed/viewed in this cell and can be used in the report generator.

ID	Shows the internally used ID of the device. This information can be changed/viewed in this cell and can be used in the report generator. The main function of this window is to link your measurement to your devices for easier reproduction.

Serial number

Shows the serial number of the device. This information can be changed/viewed in this cell and can be used in the report generator.

Software version

Shows the software version of the device. This information can be changed/viewed in this cell and can be used in the report generator.

Type

Shows the type of the device. This information can be changed/viewed in this cell and can be used in the report generator.

Additional options[edit]

The 'Device Driver Settings' window provides additional options besides changing/viewing the 'fixed information', such as:

Add

The ‘’’ ‘Add’ button’’’ can be used to add additional information items to the general device driver settings. The additional items will be shown in the list. Additional information items can be used to note the storage location, the location of the user manual, etc.

Edit

The ‘’’ ‘Edit’ button’’’ can be used to edit the information of a selected item. Information items that cannot be modified cannot be edited.

Remove

The ‘’’ ‘Remove’ button’’’ can be used to remove a selected information item from the list. Only additional information items can be removed. Fixed information items, as described previously, cannot be removed.

Zero Interval

When the Zero interval is activated, it is possible to specify a time period in minutes, in which a device does not need to be ‘re-zero-ed’. For accurate measurements it is necessary that Power Meters and Field Sensors are zero-ed. A zero operation generally takes several seconds to be completed and it may be valid for a few hours. To prevent that a device is ‘re-zero-ed’ during each test initialization, it is possible to set a zero interval in minutes. When a test is initialized and the device is already zero-ed within the specified zero interval, no zero will be performed at that time. Specifying and activating the zero interval can be a significantly reduce the time that is needed to initialize each test.

This setting is only available for power meter and field strength sensor devices.

Calibration Expire Date

This field can be used to set the date on which the device needs to be re-calibrated. Depending upon the setting in the configuration window, RadiMation^® will use this date to give warnings/notifications on the recalibration. When you press the ‘calendar icon’ to the right of this field a small window will appear, allowing you to select the new date.

Advanced

The ‘’’ ‘Advanced’ button’’’ can be used to open the advanced menu of the device driver. In chapter 15, the paragraph ‘Device specific configuration’ will explain this menu for every device type. Please note that the configuration does not apply on the configurable or virtual drivers. Please view the paragraphs about ‘Configurable devices’ or ‘Virtual devices’ (also in chapter 15) for these devices.

Check

The ‘’’ ‘Check’ button’’’ can be used to check if the device is connected. This check is the same as the check that is performed during each test initialization. This check can be used to determine if the correct addressing is set, and whether communication with the device is possible. (This option is explained further below in the paragraph ‘Checking the device connection’.)

Knowledgebase

The ‘’’ ‘Knowledgebase’ button’’’ can be used to open a new web-browser window which will show the RadiWiki page about that device driver. That RadiWiki page can contain additional information or a detailed explanation of all the advanced settings.

Checking the device connection[edit]

The 'Device Driver Settings' window contains a 'Check' button that can be used to check whether the device driver is correctly connected to the PC.

When the 'Check' button is clicked, the following actions are performed:

RadiMation tries to load the DLL of the device driver
RadiMation tries to create an instance of the device driver
The settings (as configured under 'Advanced') are loaded
The device driver is instructed to check if the (hardware) device itself is working correctly
The device driver instance is removed from memory again

If one of these steps is unsuccessful, an error message will be shown. If all the steps are successful, a message will be shown that the device connected has passed the check. (See the image below.)

This is a very helpful tool because it is a fast method to check whether the advanced settings (especially the (GPIB) address) of the device are set correctly. If this 'Check' is successful, the 'device check' during the test initialization (which performs the same check) will also be successful.

The check that is performed depends on the implemented device driver. For example, some devices (like antenna's, couplers, LISN's, injection clamps, etc.) cannot be checked for the correct connection to the PC (done at step 4), because there is no connection at all. In addition, some device drivers assume that the LASER of the device is activated before the check is successful. Despite these deviations, the 'Check' functionality will still work and show the message displayed above, as long as the device driver passes the (appropriate) check.

This functionality is available in RadiMation^® version 5.3 and newer.

Storing the driver version in the test file[edit]

For quality accreditation reasons it is necessary to store the version numbers of the hardware, firmware and software of the equipment used to perform EMC measurements. RadiMation^® uses device drivers to control this equipment. Because these device drivers greatly influence the overall (and correct) functioning of the EMC measurement, it is important that the version of these device driver is stored together with the measurements results of each test.

RadiMation^® can store all this information, most of which is also automatically determined by the program itself. This information (including the device driver version) is shown in the 'Device Driver Settings' window. (As explained further above in the paragraph 'Fixed information'.)

About the device driver information:

The numbers of the device drivers system and/or the used .dll version number of a specific device are always (slightly) different by default. An example situation is included below.

The value of the 'Device driver DLL Version' shows the date and time on which this specific .dll was compiled. (For example: 2013.07.11.1405. The date of the used .dll for this specific device is June 11, 2013 at 14:05 pm.)
The value of the 'Device drivers installation date' shows when the device driver setup was installed by the end-user for the specific version of RadiMation that is currently running. (For example: 12.07.2013 08:37:00. The install date is June 12, 2013 at 08:37 am.)
The value of the 'Device drivers versions' shows which device driver version you are currently running. This is the date and time when all the device driver DLL's are packaged into the DRIVERS.EXE. (For example: 2013.07.11.1414. The date of the device drivers system is June 11, 2013 at 14:14 pm.)

Now we can conclude that:

The Device Drivers version that is being used is 2013.07.11.1414
The used .dll version of this specific device is 2013.07.11.1405
The latest device drivers setup is installed on June 12, 2013 at 08:37 am.

It happens very often that a Device driver DLL is modified multiple times in a day. By including the time in the version number it is possible to determine exactly which DLL version is used. It is also possible that (in specific situations) a DLL is provided without using an updated DRIVERS.EXE package. In that situation the 'Device driver DLL Version' can be newer than the 'Device drivers versions'.

This functionality is available in RadiMation^® version 5.3 and newer.

4. Graphics configuration[edit]

RadiMation^® allows you to customize the way graphics are displayed on your screen.

To configure the style of the shown graphs, go to the 'Configuration' window in the 'Configuration' tab.

An example graph is shown in the 'Graphs' tab that is created with the current settings. To change these graph settings, click 'Customize' .

The 'Graph Customization Configuration' window contains three tabs; 'Chart' , 'Graph' and 'Markings' .

The 'Chart' tab contains the settings related to the overall graph and can be used to determine the colors, layout and titles.

The 'Graph' tab contains the settings related to the graph lines shown in the graph and can be used to determine the colors, scaling and layout of each and every shown graph line.

The 'Markers' tab contains the settings related to the markers on the graph and can be used to determine the colors, style and scaling of each and every shown marker.

To change the graph settings, select a graph (component) in the left section of the window, then make the desired changes in the right section of the window.

Click 'Update' to update the graph settings without closing the 'Graph Customization Configuration' window. This will allow you to see the effect of the new settings and make additional changes.

Click 'Close' to update (and save) the graph settings and close the 'Graph Customization Configuration' window. You will be returned to the 'Configuration' window.

The selected settings in the 'Graph Customization Configuration' window are used as the RadiMation^® default settings. It is still possible to overrule these settings for individual tests to more specific settings.

Click 'Restore factory default' to return to the factory settings.

5. Database configuration[edit]

Introduction[edit]

RadiMation^® can retrieve customer information (such as name and address) from external databases, for example from your company's customer relationship management (CRM) database. This option is called Customer database and will reduce the need to manually enter large amounts of customer information in RadiMation^®.

Customer database can interface with several external databases, such as:

Changing the customer database driver[edit]

To configure RadiMation^® to support your customer database, go to the 'Configuration' window in the 'Configuration' tab.

Click 'Close' to leave the 'Configuration' window.

Additional Setup for ODBC Connected databases[edit]

Text, CSV, Excel, MSSQL and MySQL dabase files need some additional setup before they can be used. The reason for this is that RadiMation^® uses ODBC to connect and read out thoes databases. This additional setup of an ODBC connection must be performed before the database driver can be configured in RadiMation^®. The configuration of the ODBC connection should be done within the Microsoft Windows operating system.

Select

Start

Settings

Control Panel

ODBC Data Sources

Now the ODBC Data Source Administrator dialog will be shown, which can be used to manage the available ODBC Data Sources.

Then Select Add... to add a new ODBC Data Source.

Depending on the required Database connection, the correct driver should be selected. The selected driver will be used to create a new Data Source when the Finish button is pressed. Depending on the selected ODBC driver, a specific driver configuration window will appear. This driver specific configuration window has to be configured to further finalize the ODBC connection with the correct parameters.

ODBC text and CSV database files[edit]

If the Microsoft Text Driver (*.txt,*.csv) is selected, it will show the ODBC text setup dialog.

The ODBC text setup dialog is used to configure the ODBC driver for a text based database.

In this window we need to set several items:

Data Source Name

This just a name for the setup you are making, name this Radimation, or another descriptive name for the used database

Select Directory...

Allows to select the directory in which the text based database files are stored

Use Current Directory

Overrules the selected directory to use the current directory. It is best to turn this checkbox off, and select a specific directory by using the Select Directory... button

Once the MSSQL ODBC Data Source connection is correctly configured, the configuration of the customer database in RadiMation^® can be performed.

6. Language Selection[edit]

RadiMation^® supports multi-language use. This means that the software package can be operated in several language.

In addition, the multi- language support allows for easy translation from English to most other languages.

Please contact your local reseller for the availability of your required language driver.

The default language of RadiMation^® is UK English.

To change the language settings, go to the 'Configuration' window in the 'Configuration' tab.

Go to the 'Language' tab. The current language setting is marked with the text (current).

To change the language setting, select one of the other languages, click 'Close' (to leave the 'Configuration' window) and restart RadiMation^®.

The selected language will only be active after RadiMation^® is restarted.

7. Measurement Settings[edit]

With measurement settings you can change the behavior of the software at certain points. Be very careful what you do with these setting, because they are used through out RadiMation^®.

Starting level signal generator[edit]

With the 'Starting Level Signal Generator' you can define the level of the signal generator at the start of an immunity test.

Perform power delivery test after pause[edit]

'Perform Power delivery test after pause' is very helpful if you chose to change the RF path during the pause.

For example:

Changing the antenna. It will show high refelected power if the antenna is not correctly connected.
Changing the switch matrix to ensure a safe working area while changing something on the EUT. It will show you whether or not you are injecting power inside the chamber.

Disable frequency zoom-in in emission tests[edit]

'Disable frequency zoom-in in emission tests' can be used to decrease the measuring time by not trying to pin point the most accurate frequency. This can be a very useful option for labs that are only interested in the overall envelope of the emission.

Warning:

Disabling the 'zoom-in in emission tests' in combination with analysers will very likely result in an incorrect measurement.

Calibration[edit]

The 'Calibration' field can be used to specify the behavior of the software with regards to the calibration date of the equipment. This may vary between 'a simple warning message' and 'stopping measurements from being done'.

Required environment settings[edit]

With the required environment settings you can force the test engineer to fill in specific Environmental Data settings. The first test done with a new EUT document requires the engineer to fill in the requested information. The second time a button will appear that will allow you to automatically fill in the same information as used in the previous test.

8. Product Standard[edit]

Introduction[edit]

Product Standards describe the requirements (e.g. dimensional, technical, etc.) and the methods of testing (as well as grading, marking, etc.) of a product.

The objective of these standards is to define and impose 'standards' that will ensure that the product in question will not represent harm or hazard to consumers.

Because the standards with regards to product testing can be relevant to RadiMation^® users, RadiMation^® offers the possibility to add this documentation to your configuration.

There are many Product Standards for individual products and product types. These, in turn, often refer to multiple Basic Standards.

Where a Product Standard describes all the tests that should be performed on a EUT, a Basic Standard only describes one single test.

For example:

The Product Standard for product X describes four different requirements/tests that the product needs to comply with.

These four tests are described in four Basic Standards, where each basic standard describes the requirements for one test.

Basic Standards can also be added to RadiMation^®.

In addition, one single Technical Setup File (TSF) can be generated for each Basic Standard, configured to perform the test as described in the standard.

Adding a Product Standard[edit]

To add a Product Standard to RadiMation^®, go to the 'Configuration' window in the 'Configuration' tab.

Select the 'Product standards' tab and click 'Add' .

(To edit a Product Standard, select the standard and click 'Edit'. To remove a Product Standard, select the standard and click 'Remove'.)

Insert the required information in the 'Standard details' window (as visible in the example below).

Please note that the Official name can only be inserted the first time and has to be unique.

In addition, it is possible to link a file to the standard in the File location field. For example a PDF, DOC or HTML file that describes the standard.

RadiMation^® will open the file (with the default reader for this file type) when the engineer selects the magnifying glass button next to that field.

To confirm your data input, click 'OK' , to cancel your input, click 'Cancel' . You will be returned to the 'Configuration' window.

Add(ing) Basic Standard(s)[edit]

To add a Basic Standard to the product standard, click 'Add' . The 'Select Standard' window will appear.

Select one or more Basic Standards (hold the 'Ctrl' key to select multiple standards) and click 'Select' .

To cancel your selection, click 'Cancel' . You will be returned to the 'Standard details' window.

To see the details of a Basic Standard, double click the standard or click 'Details'.

Note:

When a product standard is selected or added in the 'EUT' window, the data of that standard is copied into the EUT Document. At that moment a copy of the data of the standard from the configuration is made. This means that, if the configuration of a standard in the 'Configuration' window of RadiMation^® is changed, the data in the EUT file will still have the old data of the standard!!! This is as it should be, because this is the information of the standard that is used at the time that the EUT was tested.

9. Basic Standard[edit]

To add a Basic Standard to RadiMation^®, go to the 'Configuration' window in the 'Configuration' tab.

Select the 'Basic standards' tab and click 'Add' .

(To edit a Basic Standard, select the standard and click 'Edit'. To remove a Basic Standard, select the standard and click 'Remove'.

Please note that removing a Basic Standard from the list will also remove any references of this standard entered in the Product Standards.)

Insert the required information in the 'Standard details' window (as visible in the example below).

Please note that the Official name can only be inserted the first time and has to be unique.

In addition, it is possible to link a file to the standard in the File location field. For example a PDF, DOC or HTML file that describes the standard.

RadiMation^® will open the file (with the default reader for this file type) when the engineer selects the magnifying glass button next to that field.

To confirm your data input, click 'OK' , to cancel your input, click 'Cancel' . You will be returned to the 'Configuration' window.

Correction files[edit]

Correction files can be used to correct the frequency response of cables, generators, clamps, antenna’s, couplers etc. When the frequency response of a device is known, the operator can create a new correction file and assign it to the device.

Creating correction files[edit]

To create a correction file, select

File

New

Correction file

The window below will be displayed.

The first step is to define the columns in the table by pushing the Columns/Units button. A selection box appears and columns can be added or removed. Based on the use of the correction file the proper columns should be selected. For example an amplifier correction file will have two columns one frequency column and one power column. In the case of a radiated emission test three columns are required specifying frequency, correction, angle and height. For most columns, a unit can be specified. Values that are specified in this column will be interpreted as being values in the selected unit.

Entering data points[edit]

To enter data points, press the “Add row" button. A new line will appear and you can enter values in the columns.

When a data point is incorrect, it can be removed by selecting the data point and pressing the “Remove row” button.

Linear/Logarithmic interpolation[edit]

The user can select either linear or logarithmic frequency interpolation. This choice is dependent on the applicable standard.

Saving correction files[edit]

To save the new correction file please select:

File

Save correction file

RadiMation^® will prompt you to enter a filename for the correction file.

Attaching correction files[edit]

Most correction files are used for correcting a measured value of a device driver. The made correction file should therefore be 'attached' to the correct device driver.

You can attach a correction file to a device driver in the configuration screen. You can access the configuration screen by selecting

Configuration

configuration

in the main menu. The window shown below will appear.

You can select the type of device you want in the box that is situated top right. The big window will display all currently configured device drivers, like in the picture all configured Signal Generators. To edit the configuration of a device, select the device in the list and press Edit.

Now you get the configuration window of this specific device driver.

In the lower part of this window, the made correction file(s) can be selected, for one of the specified uses. The RadiMation^® software will use the specified correction files, every time when the device driver is used during a test. In this example it is possible to link an 'Output correction' file to correct the output level of this Signal generator. Depending on the type of the device driver, different uses of the correction files are available. Remark: it depends on the driver and the used correction 'link', which columns are required and therefore which correction files are acceptable to be used.

Correction file uses[edit]

Correction files can be used in many situations. The type and number of columns that should be used in the correction file is depending on the in which the correction file is used.

Amplifier: Maximum Input[edit]

The input level of an amplifier can be protected to never be above a certain power level. A correction file with the maximum input level should be attached to the device driver of the amplifier. The correction file should contain the columns:

Frequency
Correction

Or

Frequency
Power

The values in the correction column should be expressed in dBm. The value specified in the correction or power column is the maximum allowed input power of the amplifier. During the regulation of the test-level the regulation is ensuring that the amplifier input power will not become higher than the maximum input power as specified in the correction file.

If no correction file is selected for the 'Maximum Input' of an amplifier device driver, RadiMation will limit the amplifier input power to 0 dBm. 0 dBm is very often the power level that is allowed as maximum amplifier input power without damaging the amplifier. If an amplifier is allowed to have a maximum input power above 0 dBm, a correction file with the allowed value should explicitly be selected for the 'Maximum Input'.

Amplifier: Maximum Forward[edit]

The forward power level of an amplifier can be protected to never be above a certain power level. A correction file with the maximum forward power level should be attached to the device driver of the amplifier. The correction file should contain the columns:

Frequency
Correction

Or

Frequency
Power

The values in the correction column should be expressed in dBm. The value specified in the correction or power column is the maximum allowed forward power. During the regulation of the test-level the forward power level is measured and the regulation is ensuring that the forward power will not become higher than the maximum forward power as specified in the correction file.

Amplifier: Maximum Reflected[edit]

The reflected power level of an amplifier can be protected to never be above a certain power level. A correction file with the maximum reflected power level should be attached to the device driver of the amplifier. The correction file should contain the columns:

Frequency
Correction

Or

Frequency
Power

The values in the correction column should be expressed in dBm. The value specified in the correction or power column is the maximum allowed reflected power. During the regulation of the test-level the reflected power level is measured and the regulation is ensuring that the reflected power will not become higher than the maximum reflected power as specified in the correction file.

Absorbing clamp: Clamp loss[edit]

The power loss inside an absorbing clamp can be corrected inside the software. A correction file with the loss should be attached to the device driver of the absorbing clamp. The correction file should contain the columns:

Frequency
Correction

Or

Frequency
Attenuation

Or

Frequency
Gain

The values in the correction column should be expressed in dB. The values of the correction and attenuation column, are added to the measured emission level. The values in the gain column are subtracted from the measured emission level. In this way the real emission level can be calculated.

Antenna: Antenna Factor[edit]

For converting the reading dBuV into dBuV/m the antenna factor is needed.

The correction file should contain the columns:

Frequency
Correction

Where the correction column is the antenna factor.

Antenna: Magnetic Flux Density (pT/A) correction[edit]

During immunity measurements when a mangetic field has to be generated, this correction file is used to determine the current that should be generated during the magnetic field generation loop antenna. A correction file with the correction factor should be attached to the device driver of the antenna. The correction file should contain the columns:

Frequency
Correction

The value specified in the correction column should be expressed in pT/A. The values in the correction column are multiplied with the generated current to calculate the generated magnetic field in picoTesla (pT).

This correction is primarily used during the MIL-STD Magnetic Field tests. In the MIL-STD 462D, this correction value is specified as 9.5x10^7 pT/A.

Antenna: Magnetic Field Factor (dBpT/uV) correction[edit]

During emission measurements when the measured emission values have to be shown in magnetic field (Tesla) units, the correction factor should be configured in the software. A correction file with the correction factor should be attached to the device driver of the antenna. The correction file should contain the columns:

Frequency
Correction

The value specified in the correction column should be expressed in dBpT/uV. The values in the correction column are added to the measured emission levels to calculate the correct to be displayed emission values in a Tesla unit.

This same correction is also used during the MIL-STD Magnetic Field calibration for the 'calibration antenna'.

Antenna: GpsHt - AntHeight[edit]

This correction is only available when the Antenna Diagram module is activated. The height distance between the GPS receiver and the Antenna can be corrected by a correction file. A correction file with the height distance should be attached to the device driver of the antenna. The correction file should contain the column:

Height

Only one row should be present in the correction file. If multiple rows are available, only the height value of the first row will be used. The value of the height column, is subtracted from the height received by the GPS receiver. The result is the exact height of the receiving antenna for the antenna diagram measurements.

Antenna: Ant Gain vs Angle[edit]

This correction is only available when the Antenna Diagram module is activated. The antenna gain is depend on the measuring angle during antenna diagram measurements. A correction file can be used to specify the AntennaGain depending on the receiving angle. This correction file should be attached to the device driver of the antenna. The correction file should contain the columns:

Angle
Attenuation

The value of the attenuation column is added to the measured radiated power.

Cable: Cable loss[edit]

The power loss inside a cable can be corrected inside the software. A correction file with the cable loss should be attached to the device driver of the cable. The correction file should contain the columns:

Frequency
Correction

Or

Frequency
Attenuation

Or

Frequency
Gain

The values in the correction column should be expressed in dB. Cable device drivers can be used in different parts of a test-site setup. But they all have in common that an 'interesting' power-level is attenuated by the cable before it is measured by a measuring device (most of the time a powermeter, receiver or an analyzer). The values of the correction and attenuation column are therefore added to the measured powerlevel. The values in the gain column are inverted before they are added to the measured powerlevel.

Calibration Jig: Transfer correction[edit]

The transfer factor of a calibration jig can be corrected inside the software. A correction file with the correction should be attached to the device driver of the calibration jig. The correction file should contain the columns:

Frequency
Correction

The value specified in the correction column should be expressed in dB and the value is added to the typical transfer factor of a calibration jig. For example: A calibration jig is used with a typical transfer factor of 9.6 dB (correction for 150 Ω to 50 Ω). A correction file with a frequency and correction column is connected to the device driver. The value specified in the correction column for 1.23 MHz. is 0.3 dB. Then the software will use a total transfer factor for the calibration jig of 9.9 dB.

If the jig is not "Configurable" there is a default correction factor of 9.5 dB (theoretical value). We will explain how the presence of a correction factor is it taken into account by RadiMation and how this value is used by an example. For instance we have the following situation: At 150 kHz the real total correction factor of the jig is 10 dB. When this value is saved in the correction file, what will be the behavior of RadiMation? Will it now take the 10 dB as the total transfer correction? The answer is that the correction value will be added, but RadiMation will use this specified 10 dB correction on top of the internal correction value. In this case it is not correct and a correction of app. 0,5 should have been used.

There are two categories of Injection devices:

50 Ohm. (E.g. Luthi CR 100 A, Tegam 95241, FCC BCICF)
150 Ohm. (E.g. Luthi EM 101, MEB KAL-M2, MEB KAL-KEMZ, FCC F-203I-CF-23mm)

Depending on the used injection device, a matching calibration jig is necessary to correctly calibrate the injection device. Based on the impedance of the injection device, the calibration jig should be corrected with a value. In RadiMation we use the principle that we already programmed the correct correction value in the device driver of the calibration jig. This simplifies the implementation of our software, as you only have to select the correct device driver, and RadiMation automatically knows the correct correction value for the calibration jig.

This implies that:

The device drivers for the calibration jigs for the 50 Ohm injection devices already have an internal correction factor of 0 dB.
The device drivers for the calibration jigs for the 150 Ohm injection devices already have an internal correction factor of 9.5 dB (9.5424 dB to be more exact).

We are aware that it is not very clearly visible which correction factor is used inside a device driver of the calibration jig. That is why the newer device drivers, report the frequency range and the correction factor that is programmed inside the RadiMation device driver of a calibration jig. When you want to retrieve this information (shown in a 1 digit precision) just press the 'Advanced' button on the device driver configuration window.

In this example we are using a jig for a CDN where the jig has 100 Ohm resistors in the connection. In this case a 150 Ohm system (as the 100 Ohm resistors are in series with the coax which already has a 50 Ohm resistance) is used.

The calibration jig value (as a factor or as a resistance) is only used for a conversion of the impedance of the CDN to the 50 Ohm typical impedance of the coax cables and powermeters. In some RadiMation device drivers a resistance should be specified, and in other device drivers a calibration jig factor should be specified. If a resistance should be specified in a device driver, the calibration jig factor is calculated using the formula:

calibration jig factor = 20 * log10(<resistance [Ohm]> / 50)

For a 150 Ohm system the correct jig transfer factor is 9.5 dB. Depending on the selected calibration jig device driver a calibration jig factor of 9.5 dB should be selected:

or a resistance of 150 Ohm should be specified for the 150 Ohm system:

For a 50 Ohm system, (where no 100 Ohm resistors are included in the calibration jig) the calibration jig factor should be 0 dB:

or a resistance of 50 Ohm should be specified:

Coupler: Forward Correction[edit]

The forward power attenuation of a coupler can be corrected by a correction file. A correction file with the correction should be attached to the device driver of the coupler. The correction file should contain the columns:

Frequency
Correction

Or

Frequency
Attenuation

Or

Frequency
Gain

The values in the correction column should be expressed in dB. The value specified in the gain column is subtracted from the typical attenuation of the coupler. The values in the correction or attenuation column is added to the typical attenuation of the coupler. For example: A coupler is used with a typical forward attenuation of 60 dB. A correction file with a frequency and attenuation column is connected to the device driver. The value specified in the attenuation column for 100 MHz. Is 1.3 dB. Then the software will use a value of 61.3 dB for the total attenuation of the coupler.

Coupler: Reflected Correction[edit]

The reflected power attenuation of a coupler can be corrected by a correction file. A correction file with the correction should be attached to the device driver of the coupler. The correction file should contain the columns:

Frequency
Correction

Or

Frequency
Attenuation

Or

Frequency
Gain

The value specified in the gain column is substracted from the typical attenuation of the coupler. The values in the correction or attenuation column is added to the typical attenuation of the coupler. For example: A coupler is used with a typical reflected attenuation of 40 dB. A correction file with a frequency and attenuation column is connected to the device driver. The value specified in the attenuation column for 130 kHz. is 0.13 dB. Then the software will use a value of 40.13 dB for the total attenuation of the coupler.

Current sensor: impedance[edit]

The impedance of a current sensor is very important to calculate the correct measured current. The impedance is current sensor and frequency dependant. Before a current sensor can be used, an impedance correction file should be attached to the device driver of the current sensor. The value specified in the correction file is used to correctly calculate the current flowing through the current sensor. The correction file should contain the columns:

Frequency
Correction

Or

Frequency
Resistance

The values in the correction column should be expressed in Ohm (Ω).

Field sensor: Field offset[edit]

The measured value of a field sensor, can be corrected by the software. The measured value can be corrected with an offset, or it can be corrected by a multiply factor. Both corrections can also be used together but the multiply correction will be performed first, and after that the offset correction will be added. The correction files with the correction should be attached to the device driver of the field sensor. The correction file for the field offset should contain the columns:

Frequency
Correction

The values in the correction column of the offset correction should be expressed in V/m.

To summarize this in an example, let’s say that the RAW field probe measurement at 90 MHz is 10.2 V/m. When a Field offset correction for that same frequency of 2.0 V/m is specified, RadiMation will use a corrected field strength of 12.2 V/m (10.2 V/m + 2.0 V/m).

Field sensor: Field Multiply[edit]

The measured value of a field sensor, can be corrected by the software. The measured value can be corrected with an offset, or it can be corrected by a multiply factor. Both corrections can also be used together but the multiply correction will be performed first, and after that the offset correction will be added. The correction files with the correction should be attached to the device driver of the field sensor. The correction file for the multiply should contain the columns:

Frequency
Correction

The values in the correction column of the multiply factor should be expressed as x (multiplier).

To summarize this in an example, let’s say that the RAW field probe measurement at 90 MHz is 10.2 V/m. When a Field multiply correction for that same frequency of 1.1 is specified, RadiMation will use a corrected field strength of 11.22 V/m (10.2 V/m * 1.1).

LISN: Amplitude correction[edit]

The power loss inside an LISN can be corrected inside the software. A correction file with the correction should be attached to the device driver of the LISN. The correction file should contain the columns:

Frequency
Correction

The values in the correction column should be expressed in dB. The values of the correction column are added to the measured emission level. In this way the real emission level can be calculated.

Powermeter: Power correction[edit]

The measured power level of a power meter can be corrected with a certain value. A correction file with the correction should be attached to the device driver of the powermeter. The correction file should contain the columns:

Frequency
Correction

Or

Frequency
Attenuation

Or

Frequency
Gain

The values in the correction column should be expressed in dB. The value specified in the attenuation column is subtracted from the measured power level. The values in the correction or gain column is added to the measured power level. For example: A power level of -14.58 dBm is measured with a power-meter. A correction file with a frequency and attenuation column is connected to the device driver. The value specified in the attenuation column for 81.7 MHz. is 0.27 dB. Then the software will use a value of -14.85 dBm as the value that was measured with the power-meter.

Pre amplifier: Amplifier Gain[edit]

The gain of an used preamplifier can be corrected inside the software. A correction file with the frequency dependant gain of the preamplifier should be attached to the device driver of the preamplifier. The values in the correction column should be expressed in dB.

Depending on the configuration of the correction file that is selected for the preamplifier, the correct behaviour is used:

'Frequency' and 'Correction' column: The values in the 'Correction' column are interpreted as 'gain' values. A positive value is interpreted as a positive amplification of the preamplifier. These 'gain' values will be substracted from the values that are measured with the receiver/analyser.
'Frequency' and 'Gain' column: The values in the 'Gain' column are interpreted as 'gain' values. A positive value is interpreted as a positive amplification of the preamplifier. These 'gain' values will be substracted from the values that are measured with the receiver/analyser.
'Frequency' and 'Attenuation' column: The values in the 'Attenuation' column are interpreted as 'attenuation' values. A positive value is interpreted as a loss caused by the preamplifier. A negative value is interpreted as a positive amplification of the signal, caused by the preamplifier. These 'attenuation' values will be added to the values that are measured with the receiver/analyser.

Receiver: Amplitude correction[edit]

The power loss inside a receiver or a spectrum analyser can be corrected inside the software. A correction file with the loss should be attached to the device driver of receiver of spectrum analyser. The correction file should contain the columns:

Frequency
Correction

The values in the correction column should be expressed in dB. The values of the correction column are added to the measured emission level. In this way the real emission level can be calculated.

Resistor: Resistance Correction[edit]

The typical value of a used resistor can be corrected by a correction file. A correction file with the correction should be attached to the device driver of the resistor. The correction file should contain the columns:

Frequency
Correction

The value specified in the correction column should be expressed in Ohm (Ω). The values in the correction column is added to the typical resistance of the resistor. For example: A resistor of 0.5 Ω is used. A correction file with a frequency and correction column is connected to the device driver. The value specified in the correction column for 594 kHz. is 0.04 Ω. Then the software will use a value of 0.54 Ω for the exact value of its calculations with the resistor.

Signal Generator: Output Correction[edit]

The output level of a signal generator can be corrected. A correction file with the correction should be attached to the device driver of the signal generator. The correction file should contain the columns:

Frequency
Correction

The values in the correction column should be expressed in dBm. The value specified in the correction column is added to the desired carrier level and then send to the signal generator. For example: a signal generator that outputs 0.2 dB more than is specified on its display, can be corrected with a value of: -0.2
