Design of Virtual Spectrum Analyzer Based on LabVIEW

Hongwei Wang

Abstract

Based on the principle of virtual instrument,a virtual spectrum analyzer was constructed via the software platform of LabVIEW.The instrument can implement the analysis of time-domain and frequency-domain process the complex signal via adding windows and filtration,getting the parameter,such as frequency,frequency response with the display of digital,the plot of figure,the save and examine of data etc,which makes high cost lower,long development circle shorter,and manual record replaced.
