12.5 Measuring conducted EMI
Description
March 27, 2021
In this lecture, we will learn:
- Real power sources have non-zero, and highly-variable, output impedances.
- A “Line Impedance Stabilization Network” (LISN) has low output impedance at DC and a standardized impedance over the frequency range of interest.
- The LISN impedance is often provided by the input impedance of a spectrum analyzer.
