Hi, everyone. I have a simple question about using the HP8753 VNA to do the S-parameter measurements.

It seems the reference impedance is 50 ohm, how can I change it to 100ohm reference system and get the S-parameters based on 100 ohm?

If yes, can I just use the same calibration kits (50ohm load) to get that?

Thanks in advances.
