CMC can be measured with a commercial current probe (e.g. Tektronix, Fischer 
Custom Communications) and spectrum analyzer, or with a homebrew current 
transformer. Details on how I made mine are in this document:

<http://wb9jps.com/Gary_Johnson/RFI_files/LISN_by_NA6O.pdf>  I also built a 
current probe calibration fixture. Details on request.
