What is Transient Limiter

This page covers function of Transient Limiter. It mentions specifications of Transient Limiter from Keysight Technologies.

Following are the functions of Transient Limiter:
• As the name suggests it blocks the high frequency transients.
• It is used along with LISN (Line Impedance Stabilization Network) and EMC analyzer. The purpose heer is to protect EMC analyzer from large transients. This is due to the fact that when EUT (Equipment Under test) generates spikes when it is powered ON and OFF.
• It basically acts as filter and attenuator.
