Setup Phase Control

This VBScript program configures and displays Phase Sweep measurements.

The SCPI commands in this example are sent over a COM interface using the SCPIStringParser object. You do NOT need a GPIB connection to run this example.

This VBScript (*.vbs) program can be run as a macro in the PNA. To do this, copy the following code into a text editor file such as Notepad and save it on the PNA hard drive as RxLev.vbs.  Learn how to setup and run the macro.
