Re: METHOD for MEASURING COMMON MODE CHOKE IMPEDANCE

All my CMCs are home brewed and meticulously measured with professional
instruments. My usual frequency sweep runs from 1 MHz through 30 MHz.
They are broadbanded.

Assuming that "wires" (transmission line) used to make CMC are much
shorter then "lambda" across useful frequencies, how much impact do you
expect from "mismatched" characteristic impedance of CMC?

It's cool to know how to measure it, but should we ever be concerned that
CMC might have fc different from the rest of the system?
