[SI-LIST] AW: Re: S-parameter file for Pico-Probe

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
