Conducted emisisions EMC test

Hello,

please can you tell of the way to do a conducted emissions EMC test on an Automotive SMPS?
It will be driving LEDs.

Hi,

choose the proper instrument like LISN or current ring to couple the emission signals

Going to a EMC lab is the best way for that

I propose you to read the EMC norm CISPR 25 first, it has define the test method and limit. contain the test setup, config of the equipment(RBW,stepsize,dwell time),PK,QP and AV limit.

Also see the standard ISO 7637.
