PNA/VNA Measurement Uncertainty

Question asked by ecrean on Apr 21, 2006
Latest reply on Apr 25, 2006 by Dr_joel
I am using a RF switch matrix to connect a PNA to a DUT.  The RF switch matrix is de-mebedded from the measurement.  There are 3 switches in both the source and meausrement paths, and the switch repeatability is 0.03 dB and 0.45 degrees phase at 10 GHZ.

How can I ***** the effects of switch repeatability on VSWR measurement uncertainty?
