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

ESD testing

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.

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.

EFT testing

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.

Cable under test

Selection of cable on which the test is performed. The cable is created in the cable section in the EUT window.

Measurement

Configuration of the tests that need to be performed on the specific cable. Level The level applied to the cable. Note A note that can be added before performing the test relate.

Pulse shape

These parameters describe the characteristics of the applied pulses. Pulse Duration The duration of the pulse applied to the cable. Pulse Rise time The rise time of the pulse applied to the cable. Burst Duration The duration of the burst applied to the cable. Burst Repetition rate The repetition rate of the burst applied to the cable. Show Pulse Shape Display a graphical view of the pulse shape.

Test site

Test equipment In the test site window the test engineer can select which equipment list will be used during this test. Test engineer In the test engineer window, the test engineer can select its own name. The test engineer name will be stored by the test results. Equipment icon By clicking on the equipment icon, the equipment list can be viewed and edited.

Surge testing

The picture below shows the Surge configuration screen. The operator has to select cable to be tested (1 or 3 phase / 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 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. All configurations (except for the test results) can be stored in a TSF file.

Cable under test

Selection of cable on which the test is performed. The cable is created in the cable section in the EUT window.

Pulse shape

Open circuit duration The duration of the open circuit applied to the cable. Open circuit rise time The rise time of the open circuit applied to the cable. Short circuit duration The duration of the short circuit applied to the cable. Short circuit rise time The rise time of the short circuit applied to the cable.
