Hi all,
All sorted.
This VNA is not showing Zcm on screen, but, it does show S21 LogMag and Phase
at same time so you can see if LogMag value is targeting -30dB to -40dB, at
Phase at low levels, then you can guess the CM will be good.
To get the final figures, I can export the data in .s2p format, then do some
maths in a Excel spreadsheet to get the CM data and even trace the results in a
plot.
This is the spreadsheet I am using:

So, thank you everyone, specially Jim, Steve, Gary and Norm.
Happy New Year !!
73, Maximo
