Overview

This example demonstrates Phase Noise calculation on a signal acquired using an NI RF Signal Analyzer. This program is a shipping example VI included with the Modulation Toolkit for NI LabVIEW.

This Virtual Instrument is designed to work with RF communications hardware from National Instruments. To find compatible hardware for this application, visit RF Homepage.

This software is written in LabVIEW, a graphical programming language designed for scientists and engineers. For more information about LabVIEW, visit ni.com/labview.

Modulation Toolkit Example Programs
The National Instruments NI Modulation Toolkit For LabVIEW extends the built-in analysis capability ofLabVIEW with functions and tools for signal generation, analysis, visualization, and processing of standard and custom modulation formats. With this toolkit, you can rapidly develop custom applications for research, design, characterization, validation, and test of communications systems and components that modulate or demodulate signals. Applications for the Modulation Toolkit are numerous; it includes the modulation formats - AM, FM, PM, ASK, FSK, MSK, GMSK, PSK, QPSK, PAM, QAM - that are the foundation of numerous emerging wireless technologies such as 802.11 a/b/g, ZigBee (802.15.4), WiMax (802.16a), RFID, satellite communications, and commercial broadcast among others.

More information on National Instruments signal processing can be found at the Signal Processing Resource Center.
