Debugging EMC Conducted Emissions with a Spectrum Analyser. LISN setup for AC and DC-powered PCBs

In this video I demonstrate how to perform the measurement of conducted emissions with a Keysight n9000B spectrum analyser and a LISN. With one setup used for AC systems and another one for DC with two line impedance stabilisation networks featured in this video: 1. DC LISN: https://www.tekbox.com/product/tboh01... 2.
