4 Port Calibration with a 2 Port automatic calibration kit possible?

Question

I have a automatic calibration with 2 port but I want to do a 4 port calibration at my ZVA. Is that possible?

Yes, this is possible:

Connect your autocal unit to the ZVA

Enter the calibration menue of the autocal units and click on "Modify calibration settings"

--> another window opens (see attached screenshot)

At "Calibrate Ports" set the tick marks for port 3 and 4, then they are included into the calibration

Set the Port Assignments as shown in the attached screenshots

Then it is possible to close the window with "OK"

Now start the calibration ("Start"), after the measurements have been done, change the connections as necessary and click again on "Start"
