Most VNAs have a "adapter characterization" function. You simply calibrate to
the coax, then connect the probe and measure the Probe cal standards (CS-11?).
Then the VNA calculates the S-Parameters of the probe. Depending on the VNA you
will have direct access to that data, or it is stored somewhere to be used
internally for further processing. You should ask the support people if that
feature is build into your VNA.

Betreff: [SI-LIST] Re: S-parameter file for Pico-Probe
Hi,
When I order probes from GGB I always get the S21 and S11 for the probe printed
out on the box the probe is shipped. Maybe you can ask GGB to provide the data
on a file to you. In my experience GGB has always been very responsive to
requests from customers.
I have the data (in PDF format) for a 40A-SGS-400-DP probe if that helps you.
Regards
Jose

Subject: [SI-LIST] S-parameter file for Pico-Probe
We are in the process of measuring several packages in our lab and would like
to know if anyone has the following s-parameter files that describe the
behavior of several pitched Pico-Probes:
40A-SG-450-DP (signal-ground-450um-pitch) 40A-GS-450-DP 40A-SG-1000-DP
40A-GS-1000-DP
These files would not be an exact fit but would be useful if anyone has them.
Regards,
-Jory
