3.1 General
The IMU4000 is ideal for running tests in development/test laboratory environments and for outdoor service
on larger systems. For outdoor service, the IMU4000 can be fitted into a military case.
For better understanding, the IMU4000 will be divided into two parts:

The left hand part of the IMU4000 contain the control and measurements. The left hand side of the front
panel, is called the control panel.

The right hand part contains all high voltage circuits, such us high voltage source, high voltage switches,
the impulse-forming network and the coupling / de-coupling network. This part is called the operation
panel.
Fig.3.1
The power connections of the IMU4000 and the EUT are located on the rear panel. With the EUT power
inputs on the rear side and the outputs on the front side an optimum de-coupling is guaranteed. This
arrangement allows test set-up without parallel-running cables.
The IMU4000 is available with different options:
Standard with handles on both side as showed in Figure 3.1. This version is recommended for use in
development and EMC test laboratories.
19“ insert version . The handles are removed and angle brackets are fixed on both sides for fitting the
IMU4000 in a 19“ rack. When the IMU4000 is equipped with an EFT circuit the EFT output must be
maximum 50 cm above the reference ground plane.
Standard with handle in a military case
. This version is recommended for outdoor EMC testing.
