11 Electrical Fast
Transient Burst
11.1 General information
The Burst generator generates Electrical Fast Transient Bursts (EFT) as described in IEC 61000-
4-4. The source impedance of the generator is 50 Ω. The burst is a common mode transient,
coupled simultaneously to all selected paths with respect to ground. It can be selected between
using the coaxial output or the built in mains coupling network.
Test requirements must be achieved by the user according to the IEC 61000-4-4 norm. The safety
standards as written in Safety must be unconditionally fulfilled.
11.2 Burst menu
After selecting in the start menu the function “Burst”, the user has the choice between standard
and pre-compliance mode. It gets selected in the top icon bar. The Figure 11-1: EFT/BURST
Standard mode shows the standard menu. When pressing “peak voltage”, “repetition frequency”,
“burst duration” a purple bow opens up and describes visually the waveform impulse.
Furthermore, the user can select between “properties”, “trigger manual”, “Burst mode” and “direct
out”. Detailed description is to find in the following under captures. However, when no further
adjustment necessary the “Start” button can be pushed and the window (Figure 11-4: Burst pre-
compliance mode charging) gets open. When pressing the “line” button, the plug in the right
corner flashes red. As a result L, N, PE front view are connected with L, N, PE rear view and full
power supply for the EUT is provided.
