I'm programming a calibration. The cals done w/ the ECal module connected at port A to the PNA-X port 1 work fine. So now I'm trying to do a calibration w/ the ECal module connected at port A but now the PNA-X port 2. If I do a cal through the Cal Wizard, I can specify port 2 for the calibration and all is well. However, I'm unable to find the SCPI commands to tell the PNA-X to use port 2 (instead of port 1) for the ECal calibration. Please advise.
