Overview

This example uses NI-RFSA driver to acquire Power Spectrum and perform Peak Search Measurements. This program is a shipping example VI included with the Spectral Measurements 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 the 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.

Spectral Measurements Toolkit Example Programs
The National Instruments Spectral Measurements Toolkit provides a set of flexible spectral measurements in LabVIEW and LabWindows/CVI, including power spectrum, peak power and frequency, in-band power, adjacent-channel power, and occupied bandwidth, as well as 3D spectrogram capabilities. In addition, the Spectral Measurements Toolkit contains VIs and functions for performing modulation-domain operations such as passband (IF) to baseband (I-Q) conversion, I-Q to IF conversion, and generation/analysis of analog modulated signals. The combination of these optimized algorithms and the GHz processing of your PC delivers unmatched measurement throughput.

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