Create a PMAR Device and Measurement

The following program creates a new External Device: a Power Meter as Receiver, makes several power meter settings, and then creates a PMAR measurement.

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 PMAR.vbs. Learn how to setup and run the macro.
