Abstract

This paper was expounded based on the design course of the invented spectrum analyzer of LabVIEW. This Virtual Instrument(VI) is making time domain analysis and the frequency domain measurement can be progress at the same time, and gets the parameters such as frequency, frequency echoing of signal etc. after carrying on simple filtration to the complicated signal and adds the window dealing with and analyzing,it has many functions including data display and portray diagram,saves and sees about data being measured. This VI presents an user_friendly human_machine interface.
