Pulsed immunity

Introduction

The pulsed immunity test modules are used to record test data in the RadiMation® software. Most of the pulsed immunity tests are carried out manually while the test engineer enters the test results. The report generator can use the results of the tests.

The following pulsed immunity tests are implemented:

• Electro static discharge (ESD) testing
• Electrical Fast Transient (EFT) testing
• Surge testing

Starting an ESD test

Loading a TSF file

To start an ESD test, an EUT file must be defined first. From the EUT file, select

    Tests

       Pulsed immunity

          ESD

A list of Technical Setup Files (TSF files) will be displayed. The test engineer can select one of these TSF files to load all parameters from a previously defined emission test or press cancel to define a new emission test.

After the TSF file has been selected, the emission configuration window will appear.

When a TSF file is loaded, all test parameters will be already configured and pressing the start button on the right side of the screen can start the test.

When a new TSF file is loaded (by pressing New in the TSF selection window) all parameters will be at zero and can be configured by the operator.

The picture below shows the ESD configuration screen. The operator has to select test levels and pulse polarity. Furthermore the burst waveform has to be configured by the operator. The measurement results can be recorded in the right side of the screen. For each injection mode, the operator can select pass or fail and make notes in the “notes” field. All configurations (except for the test results) can be stored in a TSF file.

When a new TSF file is loaded (by pressing New in the TSF selection window) all parameters will be at zero and can be configured by the operator.

The picture below shows the EFT configuration screen.

The operator has to select the cable to be tested (AC / DC / IO). The cable under test is part of the EUT so it needs to be configured in the EUT window under cables. Furthermore the burst waveform has to be configured by the operator. The measurement results can be recorded in the right side of the screen. For each injection mode, the operator can select pass or fail and make notes in the “notes” field. All configurations (except for the test results) can be stored in a TSF file.

A list of Technical Setup Files (TSF files) will be displayed. The test engineer can select one of these TSF files to load all parameters from a previously defined emission test or press cancel to define a new emission test.

After the TSF file has been selected, the emission configuration window will appear.

When a new TSF file is loaded (by pressing New in the TSF selection window) all parameters will be at zero and can be configured by the operator.

The picture below shows the EFT Multiband configuration screen.

The operator has to select the cable to be tested (AC / DC / IO). The cable under test is part of the EUT and therefore must be configured in the EUT window under cables.

Within this window, the operator defines the test levels, timing, and coupling line configuration for each EFT sequence. Measurement results can be entered on the right side of the screen, where each test step can be marked as Pass or Fail. All configurations (except for the test results) can be stored in a TSF file for later use.

Cable under test

Selection of the cable on which the EFT test is performed. The cable is defined in the EUT configuration under Cables.

Repeat count

Defines how many times the complete EFT test configuration is executed.

Sequence list

Overview of all EFT test sequences to be performed.

Voltage test level

Specifies the burst voltage level to be applied.

Add / Duplicate / Remove

Buttons to create, copy, or delete EFT sequences from the list.

Sequence configuration

Voltage test level

Sets the test voltage level for the EFT burst.

Polarity

Determines if the pulses are positive, negative, or alternating.

Pulse repetition rate

Sets the frequency of the pulses within the burst.

Line

Shows the selected coupling device and is used to opens the Coupling Line Configuration dialog where the operator defines which coupling lines are used for the EFT test. The coupling line Configuration dialog allows the selection of the coupling line configuration for the device driver found in the testsite. The operator can select one or more combinations, depending on the test standard requirements. If no coupling path is selected the pre-existing configuration will not be overwritten. The coupling line configuration dialog does not remember the previous selected line selection. Each selected line is tested sequentially; RadiMation automatically creates individual EFT injections for each configuration. Selecting multiple lines ensures all required coupling paths are tested without manual re-configuration between runs. If no line is selected when starting the test, RadiMation prompts the user to select at least one coupling path before the test can start. When multiple coupling paths are selected, RadiMation automatically performs a separate test for each selection in sequence. The order in which testing on the coupling lines is performed is undefined.

Note:

The coupling configuration dialogue is added in RadiMation 2025.2.1, in older RadiMation releases a single tested coupling line is selected from a predefined list.

Furthermore the operator has to configure the test level, polarity, phase and the internal resistor and capacitor of the generator. The measurement results can be recorded in the right side of the screen. For each injection mode, the operator can select pass or fail and make notes in the “notes” field.
