When developing my nanovna mini-tools, I am unclear about the "Touchstone" file format
regarding the storage of Z-parameters for a one-port (nanovna_snp.py). So far I follow rev
1.1, it says on page 7:
In a .S1P file it is not an impedance that is described but S11
# HZ S RI R 50
6800000 0.4178235144152254 -0.6694732263322638
For each line you find in order:
Frequency in Hz
the real part of S11
the imaginary part of S11
If you want the impedances you have to recalculate them from S11
