Herb,
As you know S-Parameter files are actually text files.
The line with the "#" character is the format string for the file. This may or may not be the first line in a file.
In the case above, the frequency is in Hz, this is an S-parameter file, the data values are Real and Imaginary because the header has "RI" and the impedance system is Resistive and 50 Ohms.
1st column is frequency in Hz, indicated by Hz in the first line,
2nd column is S11 real part (-0.009529378 above)
3rd column is S11 imaginary part (0.000616876 above)
4th column is S21 real part (0.019876752 above)
5th column is S21 imaginary part (0.001359617 above)
6th column is S12 real part (0 above)
7th column is S12 imaginary part (0 above)
8th column is S22 real part (0 above)
9th column is S22 imaginary part (0 above)
nanoVNA-Saver does not save the data in dB format.
I hope this helps.
