Electrical Fast Transient Burst (EFT) Immunity Test Setup
EFT Test Setup
Setting up for EN/IEC 61000-4-4
Most of our customers will simply place the EFT generator on a bench, ground it to the chassis, and be off and rolling. There are diagrams avaialble that specify spacing, insulation, placement of the generator, etc... We have found that in most cases, these aren't detrimental pieces to passing IEC 61000-4-4.

Automotive Transient Setup
Injecting electrical transients onto automotive products has grown more sophisticated with advancement and demand of technology integrated with our EV's and other automobiles. New test standards, such as CISPR 25, will require a cable harness carrying high and low voltage lines to simulate most electrical systems of common car manufacturers.

In-situ/Large EUT EFT Test Setup
Installing, troubleshooting or certifying large electronics drawring three phase power or large DC current require considerations not always detailed in IEC 61000-4-4 or other normative standards.
Ensuring proper grounding, insulations as well as power line filtering may be needed at certain points within the test circuit.
