Device drivers

Introduction

Device drivers are the lowest layer in RadiMation®, they make it possible to communicate with thousands of different devices. They make the system flexible, while the RadiMation® Core stays generic. The RadiMation® Core does not even know which device it is controlling, only the type of device. So, if you have bought a new spectrum analyser or signal generator you only have to tell the software to use this new device and all the rest stays the same.

This chapter only describes the device driver specific configuration. All the configuration of the device drivers that are managed by the RadiMation® Core, are described in Chapter 14: 3. Device Driver configuration. Also the common device driver settings are described in Chapter 14: Device Driver Settings.

Virtual device drivers

For testing and demonstration purposes, virtual device drivers are added as well. These virtual device drivers act as a normal device but do not control real hardware.

Virtual device drivers do not have limitations like normal device drivers (like frequency band, maximum power, sweep times, etc.)

Configurable device drivers and non-configurable device drivers

RadiMation® supports two types of device drivers, configurable and non-configurable device drivers. Configurable devices for instance are powermeter, signal generators and spectrum analysers. For these devices you can set the IEEE address or the serial port which RadiMation® has to use to be able to communicate with these devices. Non-configurable devices are couplers and calibration jigs. You might think that it is useless to have non-configurable drivers, but the opposite has been proven many times. Non-configurable drivers still contain important information like the start and stop frequency of a device. With this information RadiMation® can prevent the test engineer from making large mistakes, like using the wrong coupler in a certain frequency range.

Device specific configuration

Signal generator

Pressing advanced will open an IEEE configuration screen. Please view chapter IEEE setting for a complete description. See Chapter 14: Correction files and Chapter 14: Correction file uses for correcting this device.

Amplifier

When an amplifier can be remotely controlled the specific window will appear. Please view chapter IEEE or RS232 setting for a complete description. When the amplifier can not be remotely controlled the message This Device cannot be configured will appear. See Chapter 14: Correction files and Chapter 14: Correction file uses for correcting and protecting this device.

Coupler

When pressing advanced the message This Device cannot be configured will appear because this device can not be controlled remotely. See Chapter 14: Correction files and Chapter 14: Correction file uses for correcting this device.

Powermeter

Power Meter Configuration Window.png


ScreenElementDescription.png Pre Wait time The minimum time that should be waited before the measurements starts.
ScreenElementDescription.png Measure The minimum amount of measurements that RadiMation® has to perform to determine if the <Max. Difference> condition is met.
ScreenElementDescription.png Wait time The minimum time that RadiMation® should be waiting between each measurement.
ScreenElementDescription.png Max. Difference The maximum difference that is allowed between the <Measure> measurement value(s); the highest and the lowest values are compared.
ScreenElementDescription.png Max. Measure The maximum amount of measurements that could be performed by RadiMation®, before there is a final measurement value available (which could meet these conditions, or not).

If Measure is set to a value of 1 the Wait time, Max. Difference and Max. Measure settings will be disabled, because only one measurement will be performed.

Now that all windows have been generally explained, the procedure RadiMation® uses is the following. RadiMation® takes the amount of measurements as defined in the Measure window. After that RadiMation® determines the minimum, maximum and difference. When the difference is equal or smaller then defined in Max difference RadiMation® determines the power. If the difference is greater then defined, RadiMation® takes one new measurement. Replaces the oldest value with the new one. Determines the minimum, maximum and difference again. This continues as long as the difference is larger then defined and the maximum amount of measurement has not yet been reached. If the maximum amount of measurement has been reached the last measurement is taken as the measured value.

See Chapter 14: Correction files and Chapter 14: Correction file uses for correcting this device.

Information.png
Note: Speed up(1): Sometimes slower means faster. For instance, if you have a slower powermeter (resistor head) it may be quicker to have a longer waiting time. Because the powermeter has more time to determine the right value, RadiMation® needs less measurements to determine the value. It is up to the engineer to find the right accuracy vs. time setting.

Speed up(2): When using a spectrum analyser a small amount of samples may be sufficient to determine the right amount of power. It is up to the engineer to find the right accuracy vs. time setting.

Measuring: Powermeter who doesn't have a RMS detector, should not be used in Fast constant mode.

Field Sensor

Field Sensor Configuration Window.png


ScreenElementDescription.png Pre Wait time The minimum time that should be waited before the measurements starts.
ScreenElementDescription.png Measure The minimum amount of measurements that RadiMation® has to perform to determine if the <Max. Difference> condition is met.
ScreenElementDescription.png Wait time The minimum time that RadiMation® should be waiting between each measurement.

If Measure is set to a value of 1 the Wait time, Max. Difference and Max. Measure settings will be disabled, because only one measurement will be performed.

Now that all windows and buttons have been generally explained, the procedure RadiMation® uses is the following. RadiMation® takes the amount of measurements as defined in the Measure window. After that RadiMation® determines the minimum, maximum and difference. When the difference is equal or smaller then defined in Max difference RadiMation® determines the field. If the difference is greater then defined, RadiMation® takes one new measurement. Replaces the oldest value with the new one. Determines the minimum, maximum and difference again. This continues as long as the difference is larger then defined and the maximum amount of measurement has not yet been reached. If the maximum amount of measurement has been reached the last measurement is taken as the measured value.

Information.png
Note: Speed up: Sometimes slower means faster. For instance, if you have a slower field sensor it may be quicker to have a longer waiting time. Because the field sensor has more time to determine the right value, RadiMation® needs less measurements to determine the value. It is up to the engineer to find the right accuracy vs. time setting.

Axis setting panel

Field sensor Advanced settings Axis Configuration.png

The Axis configuration is a generic driver setting panel. There are several (old) field sensors which don’t support the read out of an isotropic value: instead they provide the measurements values of all three axes separately. Using the ‘Software isotropic’ setting in the device driver can then activate that the measurement data of all three axes are being interpret and calculate to the isotropic value and have this isotropic value being return as the measured field strength. When the field sensor already supports the retrieval of the isotropic measurement value, often this value is also returned when the software option is being selected in the device configuration: both isotropic as software isotropic will return the isotropic value of the field sensor. This is depending on the device driver and used equipment.

Normally, this setting is set to ‘Isotropic’ in case the isotropic value should be returned.

Communication settings

Depending on the brand and model of the device, it may be necessary to specify the parameters for the communication with the device. The GPIB/IEEE 488 and RS232 buses are most commonly used. This section describes which communication buses are supported and which communication parameters can be configured. Not all devices support all the communication buses, so only the applicable communication buses can be selected in the device driver configuration.

RS-232 Setting

The RS-232 Communication settings are used to specify the RS-232 communication parameters, for the communication with a measurement device over RS-232. A lot of modern measurement devices are connected by USB, however very often then a Virtual RS-232 COMPort (VCP) is generated over the USB connection. In that situation also the RS-232 communication settings should configured.

RS-232 DeviceStream Configuration.png


ScreenElementDescription.png COM Port The COM port which RadiMation® has to use to be communicate with the measurement device.
ScreenElementDescription.png Baudrate Allows to configure the baudrate that should be used to communicate with the measurement device. This setting can be a fixed device specific value, in which case it cannot be configured and then the setting will be disabled.
ScreenElementDescription.png Data bits Allows to configure the number of data bits that should be used to communicate with the measurement device. This setting can be a fixed device specific value, in which case it cannot be configured and then the setting will be disabled.
ScreenElementDescription.png Parity Allows to configure the parity bit that should be used to communicate with the measurement device. This setting can be a fixed device specific value, in which case it cannot be configured and then the setting will be disabled.
ScreenElementDescription.png Stop bits Allows to configure the number of stop bits that should be used to communicate with the measurement device. This setting can be a fixed device specific value, in which case it cannot be configured and then the setting will be disabled.
ScreenElementDescription.png Send termination Allows to configure if and which terminator should be used during data transmissions to the measurement device. This setting can be a fixed device specific value, in which case it cannot be configured and then the setting will be disabled.
ScreenElementDescription.png Receive termination Allows to configure if and which terminator should be used during the receiving of data from the measurement device. This setting can be a fixed device specific value, in which case it cannot be configured and then the setting will be disabled.
ScreenElementDescription.png Receiving a NewLine ends read Allows to configure if a read should be ended as soon as the receive terminator is received from the measurement device. This setting can be a fixed device specific value, in which case it cannot be configured and then the setting will be disabled.


GPIB Setting

The GPIB Communication settings are used to specify the GPIB communication parameters, for the communication with a measurement device over GPIB.

GPIB DeviceStream Configuration.png


ScreenElementDescription.png Primary Address The primary address specifies the address of the device, so if the device you want to configure is on address is on 20 you enter 20. Please consult the manual of the device how to determine the GPIB address of the device.
ScreenElementDescription.png Use advanced configuration Allows the end-user to enables the more advanced configuration parameters. Those advanced option should only be used if the default settings are not sufficient enough.
ScreenElementDescription.png GPIB Board With GPIB Board you can specify the GPIB board that is used. The default value is 0 and can only be different when multiple GPIB boards are present.
ScreenElementDescription.png Secondary Address The second address is default 0, and should only be changed when needed. For further information please look in the help of National Instruments 488.2.
ScreenElementDescription.png GPIB Delay GPIB delay is the delay between GPIB reading and writing actions. Some older IEEE 488.2 machines have difficulty communicating with fast PC's (> 2.5 GHz). This is most of the time noticeable when a driver is sometimes working and some times gives a GPIB (EABO or TIMO) error. These errors are most of the time, generated randomly. Specifying a GPIB delay time of 3000 uSeconds can fix these random errors. Run the test again and see of the problem as disappeared. Is the problem has disappear then your problem was timing, if not please contact your reseller and report the problems you are having.
ScreenElementDescription.png Clear device during initialisation Enabling this checkbox will send a reset to the device during initialisation.
ScreenElementDescription.png Readdress device Enabling this checkbox will.


VISA Settings

The VISA Communication settings are used to specify the VISA communication parameters, for the communication with a measurement device. The VISA library is a higher level communication library that supports different kind of communication methods. RadiMation® doesn't provide a VISA library itself, and thus requires that a VISA library from another supplier like National Instruments or Keysight Technologies is installed. The VISA manager that is provided by that VISA library can be used to determine the correct VISA resource. The selected VISA configuration thus also has influence if a measurement device is controlled by GPIB, RS-232, LAN, USB-TMC, VXI11, network-socket or another communication method .

VISA DeviceStream Configuration.png


ScreenElementDescription.png Alias Allows to specify a VISA Alias that should be used for the communication with the measurement device. Any Alias that is supported by VISA is accepted. The correct Alias can be determined by using the VISA manager (eg. National Instruments MAX) that is installed on the PC.
ScreenElementDescription.png GPIB Allows to specify that GPIB should be used for the communication with the measurement device. The GPIB address of the measurement device should be specified.
ScreenElementDescription.png LAN Allows to specify that a VXI11 or LXI connection should be used for the communication with the measurement device. It is possible to specify the IP-address or the (FQDN) hostname of the measurement device.
ScreenElementDescription.png RS-232 Allows to specify that a RS232 (ASRL in VISA terms) connection should be used for the communication with the measurement device. The COM port of the measurement device should be specified.
ScreenElementDescription.png Visa-ID Allows to specify a VISA Identifier that should be used for the communication with the measurement device. Any VISA Identifier that is supported by VISA is accepted. If one of the other communication methods is selected the corresponding VISA Identifier is also shown in this setting. Often used VISA identifiers are:
  • TCPIP[board]::<IP-address>::INSTR: VXI11 or LXI ethernet communication with the device with '<IP-address>'.
  • TCPIP[board]::<IP-address>::<port-number>::SOCKET: Raw socket based ethernet communication with on the port '<port-number>' with the the device '<IP-address>'
  • GPIB[board]::<primary address>::INSTR: GPIB communication to the GPIB device with the address '<primary address>'
  • ASRL<port>::INSTR: Serial communcation on COM-port '<port>'


USB Settings

The USB Communication settings are used to specify that an USB connection to a DARE!! Instruments measurement device is used. It is not possible to use this USB communication setting for devices that simulate a Virtual COMPort (VCP) over an USB connection. The RS232 Settings should be used for such a kind of measurement device.

USB DeviceStream Configuration.png


ScreenElementDescription.png Device Identifier The device identifier (which is an unique identifier of 8 groups of digits) that identifies the measurement device that is connected over USB.
ScreenElementDescription.png Detect Will automatically determine the correct Device Identifier for the measurement device that is connected.


TCPIP Settings

The TCPIP Communication settings are used to specify that a socket based TCPIP connection to a measurement device should be used.

TCPIP DeviceStream Configuration.png


ScreenElementDescription.png Address Allows to specify the IP-address or the (FQDN) hostname and the socket port number of the measurement device. This is normally done with a string like: "tcpip://<address-or-name>:<port-number>", where '<address-or-name>' is the IP address or hostname, and '<port-number>' is the socket port number on which the connection should be initiated. If the socket port number is a fixed port number, it is already shown as the default value, and it will be automatically added when no socket port number is specified.


Virtual devices

Virtual devices are devices that act like normal devices but do not really exist. If you create a test site with only virtual devices, you can perform complete virtual tests. You might wonder why RadiMation® supports virtual device drivers. It is mainly used for debugging and solving software problems, but is has proven to be very useful when used as a temporarily workaround. For example a test site has an amplifier that is IEEE controlled and one day somebody accidentally destroys the communication between computer and amplifier. The test engineer has to perform some tests, he switches the driver for the amplifier for a virtual one. Sets the amplifier in operate by hand and was able to perform the tests that day. When the communication was repaired he changed the driver back again

Configurable devices

RadiMation® allows the user to create its own device drivers for test equipment, which is (not yet) implemented in the standard device driver list.

User configurable device drivers are available for nearly all types of test equipment. However, device drivers for spectrum analysers and measurement receivers can not be made with user configurable device drivers because the complexity (and differences between suppliers) of these devices is too high.

To make your own device driver, use the “Device drivers” tab in the “Configuration” > “Configuration” menu and follow the steps below:

  1. In the device driver’s menu, select the required device driver type.
  2. Press the “New” button.
  3. Select the driver called “Configurable xx” (i.e. if you want to make a signal generator device driver you would select the “Configurable signal generator” device driver).
  4. Enter a description for the device driver (for example the type number of the generator) and press OK.
  5. The name of the device driver will be added in the available device driver’s list.
  6. Select the new device driver from the available device device’s list.
  7. Press the “Edit” button.
  8. A configuration screen for the device driver will appear. All required control commands for the device must be entered. Refer to the operating manual of the equipment for these codes.

After all codes are entered, the device driver is ready for use.

The custom-made device driver can be used as any other device driver by selecting the driver in the Equipment list.

Information.png
Note: Passive equipment such as antenna’s, current probes, cables etc. do also need a device driver.

The reason for this is that RadiMation® has to know a number of parameters of these devices. Among others the following information is relevant:

  • Frequency range
  • Maximum input power
  • The report generator needs to know which equipment is used during a test
  • Correction files for these devices

Generic settings

Start and stop frequency

The most generic setting is the start and stop frequency. The default value for the start frequency is 1Hz and for the stop frequency is 40 GHz. The creator of the device is encouraged to set the right start and stop frequency. If the start and stop frequency are set correctly RadiMation® can warn the test engineer when he/she want to use the device out of its valid frequency range.

Reset

In the reset window you need to specify the string that the software needs to send when it want to reset the device. For example *RST is commonly used reset string. If you don’t know the string then leave this window blank, and make sure that the device in a neutral state.

Init

In the init window you need to specify the string that the software needs to send when it want to Init the device. For example *RST is commonly used reset string.

Get ID

In the Get ID window you need to specify the string that the software needs to send when it want to get the ID string of the device. For example *IDN? is commonly used Get ID string. Returned ID

In the Returned ID window you need to specify the string that the software will receive so that it know that it has the right device. For example "Hewlett_Packard,8643A," can be used for the Hewlett Packard 8643A. If you leave this window empty then all returned strings are accepted.


Signal generator

Configurable Signal Generator Window.png

ScreenElementDescription.png Set Frequency Set Frequency is the string that needs to send to set the signal generator frequency. The unit is in MHZ, so the string should be made for MHz.

Example: “FRQ__freq__MHZ”.

Example: “FRQ__freqHz__HZ”.

Powermeter

Configurable Power Meter Window.png

ScreenElementDescription.png Set frequency Set Frequency is the string that needs to send to set the powermeter frequency. The unit is in MHz, so the string should be made for MHz.

Example: “FRQ__freq__MHZ”.

__freq__ will be replaced by the value that RadiMation® want to set the powermeter too. The “__” of “__freq__” are two “_”.

ScreenElementDescription.png Select Channel Set Select Channel is the string that RadiMation® needs to send to set the powermeter channel. This is only necessary when the powermeter has more the one channel.

Example: “P1,U1”.

ScreenElementDescription.png Trigger Trigger is the string that RadiMation® needs to send to trigger the powermeter.

Example: “X1”

ScreenElementDescription.png Result Format Result Format is the string that RadiMation® needs to use to decode the value from the string send by the powermeter. The return value is interpreted in dBm.

Example: “__result__”

__result__ will be replaced by the value that RadiMation® get from the powermeter. The “__” of “__result__” are two “_”.

ScreenElementDescription.png Start Zero Start Zero is the string that RadiMation® needs to send to start zeroing the powermeter.

Example: “O1”

ScreenElementDescription.png Duration Duration is the time that RadiMation® waits so that the powermeter can zero properly. Make sure that this time is big enough, an incorrect value may result in unpredictable result.

Amplifier

The Configurable Amplifier device driver is a Amplifier which is supported by RadiMation®.

The configurable amplifier device driver can be used to control amplifiers for which no RadiMation® device driver is present yet. By specifying the correct commands, it is possible to send the desired commands to an amplifier. However be aware that this device driver is simple and is not able to perform more complicated tasks. Including delays and sending multiple commands at once is not possible in this device driver, a programmed device driver is needed to achieve that. Also the retrieval of the actual status of the amplifier is not supported by this configurable device driver, as the interpretation of the correct response should be very versatile.

AD converter

The Configurable AD Convertor device driver is a AD Converter which is supported by RadiMation®. It can be used to control other measurement equipment, for which no RadiMation device driver is available yet. The Configurable AD Convertor allows to retrieve a measurement value from the measurement equipment, where the measured value can then be used in RadiMation as an EUT Monitoring input. These values can thus be measured and shown in graphs during immunity tests.

Configurable AD Converter Configuration Window.png

Communication

Multiple communication types can be selected for the configurable AD convertor. Depending on the connection that is used, select the correct Communication Stream, and configure the parameters correspondingly.

ConfigureCommunication.png

Initialisation and Check

ScreenElementDescription.png Reset The reset code that needs to be send to device. When left blank, no command will be send.
ScreenElementDescription.png Init The command that is send to initialize the configured device. When left blank no command will be send.
ScreenElementDescription.png Get Id The command that is send to retrieve the ID of the device. This is used to check if the device is connected. A commonly used SCPI command is: *IDN?. When left blank, no command will be send.
ScreenElementDescription.png Returned ID The identifier is used to check if the correct device driver is selected and the device is connected. Leaving this blank, will skip the device check.
ScreenElementDescription.png Deinit Specifies the command that is send when the device is no longer controlled. This can for example be used to put the measurement device is an intrinsic safe state. Leaving this blank, will keep the device in its last state after controlling it.
ScreenElementDescription.png Wait for Completion after sending command The checkmark can be enabled so RadiMation® will wait for all the commands to complete, before it continues. This is done by sending SCPI command *OPC? to the device.


Channels

AD convertors can have multiple channels on which AD values could be read. The Configurable AD Convertor device driver is able to retrieve up to 40 measurement values from the measurement device. For each AD channel, individual commands can be set, specific for the values that should be retrieved.

Trigger and Reading

ScreenElementDescription.png Trigger A trigger command can be specified to request a measurement from the device. A commonly used SCPI command is: *TRG. When left blank, no command will be send.
ScreenElementDescription.png Read Back Different measurement devices will return different messages that contain the measurement value. The configurable AD convertor only needs the numeric value of the measurement device response. The text that is specified in the Read Back box, is used as a regular expressions to determine the returned value.

A good regular expression for finding the first number in scientific notation in a text is:

([+-]?[0-9]*\.?[0-9]+([eE][+-]?[0-9]+)?)

For more possibilities see the example section.

ScreenElementDescription.png Validate Expression Shows a window where the expected output of the measurement device and a regular expression can be typed. The result of the interpretion will then automatically be shown. This window can be used to test the regular expression, to determine if the expected response results in the desired value.


Minimum and maximum value

The minimum and maximum must be set to calculate the raw AD convertor value to a digital value with a specific type.


ScreenElementDescription.png Minimum value The lowest value that can be measured with this device. The value must be the same as filled in the EUT window.
ScreenElementDescription.png Maximum value The highest value that can be measured with this device. The value must be the same as filled in the EUT window.


With minimum set to 0 and maximum set to 1, the raw value won't be converted, but instead directly used as it is included in the response.
