Monitoring input channel setup

Warning:

General

The Monitoring input channel setup window can be opened by opening a new or existing EUT file:

    File

       Open

          EUT or

    File

       New

          EUT

Then select the 'Monitoring input channels' panel. This window enables the end-user to configure the used AD-Converter during the test:

Settings

Description

Enter the description of the device. E.g. use the brand and/or identification number.

Device

From the dropdown the used AD-Converter driver can be selected.

Channel

Based on the selected driver the amount of available channels are shown. In the past only eight channels were allowed. Older devices are still be limited to support a maximum of eight channels in this list, while their driver supports more channels.

Unit	Enter the unit corresponding to the values which will be retrieved from the device.

Calculation

None	RadiMation will not apply any additional calculations to the value the device driver is returning.

Offset

RadiMation will additionally apply the specified offset to the retrieved value by the device driver. Similar to the formula (offset+x).

Multiply

RadiMation will additionally apply the specified multiply factor to the retrieved value by the device driver. Similar to the formula (multiply factor*x).

AD input range

RadiMation will not apply any additional calculations to the value the device driver is returning.

Formula y(x)

RadiMation will additionally apply the specified formula to the retrieved value by the device driver.

The formula is using the powerful Python engine for maximum flexibility.
You can find the math functions on: https://docs.python.org/2/library/math.html
The following example will multiply the AD value by 2. And add (9^0.5)==(√9)==3

It is needed to match the expected value with the retrieved value by the device driver. Especially for older device driver it is needed to specify the allowed value range of the device. For instance:

Measure

This setting will determine when the measurement will be performed during the test. One or more of the available options can be selected.

Before dwelltime

RadiMation will perform the measurement of the configured monitoring input channel before the start of the dwell-time, just before the selected modulation is being activated.

During dwelltime

RadiMation will perform the measurement of the configured monitoring input channel during the dwell-time.

After dwelltime

RadiMation will perform the measurement of the configured monitoring input channel after the dwell-time has ended, and the selected modulation has been turned off.

Range

Enable Min Range

This will show a graph line of the specified minimum in the graph and table.

Min	The value of the minimum line in the graph and table.

Enable Max Range

This will show a graph line of the specified maximum in the graph and table.

Max	The value of the maximum line in the graph and table.

This information is also used during the 'Minimum Performance' measurements. As long as the measured value from the EUT monitoring input channel is within the specified Min and Max values, it is assumed that the EUT is not being influenced by the immunity test. If the measured value is above the specified Max or below the specified Min value, RadiMation assumes that the EUT is being influenced, and the 'Minimum Performance' test will then reduce the generated disturbance.

Equipment Under Test

Analog to Digital

The ability of an EUT to be immune to incoming electromagnetic interference. This is equivalent to the term susceptibility that is used by some standards.
