1 Generator
Select the desired Waveform and Ground Injection as coupling type.
2 Connection cable
The 2m MC-cable is connected between the EUT and the generator output. The generator is
protected with a 16A / 250V fuse against overcurrent.
3 Voltage monitor
During the test, peak voltage must be monitored to ensure the amplitude does not exceed the test
level. The pulse shape is not relevant.
4 Current monitor
Use a current probe to monitor the current during the test to ensure the peak does not exceed the
limit level.
5 Oscilloscope
The oscilloscope must have a minimum bandwith of 500 MHz.
4.6 Cable Induction WF4
The preferred coupling method for WF4 is Ground Injection. Ground Injection is possible directly
with AVI3000 without any additional coupling device. The CN-GI-CI-V is only neccessary if WF4
will be applied as Cable Induction test.
4.6.1 System Calibration
Prior to each test, the system has to be calibrated. The calibration is made at the desired test level with
both polarities.
The tests can be realized with 1 or 2 turns on the coupler output. With 2 turn, Level 3 can be
achieved with every kind of load. In many cases is it also possible with one turn on the output.
The setting has to be considered in the calibration and later in the EUT test. The ratio is also
selectable in the generator parameters.
