Using VNA N2552A. How to prevent ports that are part of calset, but not the setup, from sweeping.

Question asked by cbquestci on Jul 12, 2018

I'm using an N5225A.  My problem is how to turn off the sweeping of unused ports that are in my calset but not part of my setup. I can turn off output, but the PNA still sweeps those ports sequentially. I do 3 and 4 port calibrations for my test scenarios. When I setup, say an S12 sweep and use a calset for S1, S2 and S4, the PNA sweeps all 3 ports resulting in S2 outputing RF only 33% of the time. My UUT is expecting a constant input.
