Hi Oristo

When the cal kit calibration kit is loaded in the VNWA software you simply open a custom trace and in the Expression line write s_load or s_open or s_short or s_thrumatch or s_thru then the trace is shown according for the custom trace to be shown as you like in Smith, dB of what ever representation and then to save directly as s1p file by a right click on the trace and use the "Export to s1p file" function. You must decide on frequency span and number of points in advance

Simpe as that ?

Kind regards

Kurt

Thanks for the links.!

One problem is that scikit-rf wants S11 files for ideal SOL but I did not find how scikit-rf can generate S11 from e.g. delay, R, L, C values.



Since I have SDR-Kits BNC cal kit,

perhaps S11 for those can be generated using VNWA software, but scikit-rf also seemingly does no interpolation; raw measurement frequencies must match ideal S11, so that will be another challenge.
