This example sets Phase Reference Cal properties, then performs a Phase Reference calibration.
It is NOT necessary to create an SMC measurement before performing a remote Phase Reference Cal. It is necessary when performed from the user interface.
This VBScript (*.vbs) program can be run as a macro in the VNA. To do this, copy the following code into a text editor file such as Notepad and save it on the VNA hard drive as PMAR.vbs. Learn how to setup and run the macro.
