I have set up a PNA-X with several Channels. One of the Channels shall be used as CW-source. If I omit the CW Channel from "Cal All" power level is not calibrated and if I include the Channel then 2-port calibration is applied i.e. source port will "toggle". Is there a way to set up the CW Channel or "Cal All" for calibrated power and still have a CW signal?
Yes, there is. include your CW channel in Cal All and after the calibration is done, in the CW channel, you can change the correction method from a 2-port to a 1-port. under the Cal menu, find the Correction Methods... option and you will see this dialog:
In this case, I've excluded all the ports except for port 1, because I wanted the CW source out of port 1. you can choose whichever source port you want to use as the CW source. It will be calibrated since it was included in the Cal All. If you have an older version of the firmware or if you are on an A model PNA-X (BTW, this is why you should always include the model number and the firmware version of your VNA when you post a question), then you can do the same thing with a SCPI command (CALC:CORR:TYPE).
Luckily we have a B-model and using FW A.13.60.06. It seems like this solution works, Thank You!
