Create a Differential I/Q Measurement

This example program creates a Differential I/Q measurement setup.

This VBScript program can be run as a macro in the VNA. To do this, copy the code into a text editor file such as Notepad and save on the VNA hard drive as DIQ.vbs. Learn how to setup and run the macro.

See the Differential I/Q commands.
