PNA-X Hot S22 Measurement

Question asked by Balanar on Oct 30, 2007

I am trying to setup a dual source PNAX to measure an amplifier which is operating at non linear region which means there would be components of fo, 2fo, 3fo... etc exist in the output when fo is supply to the amplifier input. I would like to measure the S22 of the amplifier output during operation. Is the normal SOLT calibration sufficient for this measurement or is there any special calibration needed in order to get an accurate S22 measurement??
