Thanks @cdev for the response, though what I'm asking about is not file format conversions, but about the formula to convert the loss terms from the Keysight format (Offset loss in G
/s and Offset Z_o in
) to the R&S loss format (dB/sqrt(GHz)). The rest of the conversions for the fringing capacitance and parasitic inductance model, and the delays are easy enough since they're just a unit conversion. This is outlined in the link posted earlier by @TheSteve.
The cal kit also comes with the s1p files for the open, short and load standards (but not the s2p files for the thrus). I found the
thread describing the Octave scripts used to generate the fringing capacitance and inductance polynomials, but they also output loss terms in the HP format. Applied for a Metas VNA Tools download, waiting for that to come through.
