摘　　要：介绍基于LabVIEW的虚拟频谱分析仪的设计过程。这个虚拟仪器 (VI)能够同时进行时域分析与频域分析 ,在对复杂信号进行简单的滤波和加窗处理、分析后 ,得到信号的频率、频率响应等参数 ,并能完成数据显示、绘制图形、存储和查看测量数据等功能。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.
