Create a Spectrum Analyzer Measurement

This example program creates a Spectrum Analyzer measurement setup.

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

See the Spectrum Analyzer commands.
