 Overview

Coding that exemplifies how to graph the Power Out vs Power In with a constant increment.

 

Description

This code consist on incrementing constantly the RF input power and analyze how it affects the RF output power. For this example, we are using a VST 5644R connected as a loopback test.

 

Requirements
1. LabVIEW 2012 or compatible
2. NI RFSG Driver
3. NI RFSA Driver
4. Signal Generator card
5. Signal Analyzer card

 

Steps to Implement or Execute Code
1. Add the Signal Generator and the Signal Analyzer in the respective field.
2. Set the Starting Power Level, the Ending Power Level, and the amount of increment you would like to do.
3. Run the VI.
