Hello Roger,
Using Series though, the NanoVNA measures both a S11 and S21 (for that
configuration, which I [of course] calibrated). The link I gave (
), calculates the Zdut using
these Sx1 from the 2port series through measurement.
By the way, NanoVNA Saver uses also these formulas to plot the S11 and S21
for the 2port series through measurements (Sx1 R+jX [series]). IMHO these
two should be quite the same, but they are in my case quite different (as
you could see in the earlier screen grab of NanoVNA Saver.
All the best,
Victor
