摘　　要：为了解决传统频谱分析仪功能和使用的局限性,提出了一种基于LabVIEW的虚拟频谱分析仪设计方案,方案采用模块化编程思想,包括信号模块、滤波器模块、时域分析模块和频域分析模块。通过测试分析,该频谱分析仪能够实现信号时域和频域分析的功能,具有界面设计简单,便于操作等优点,能够被用于实验教学中。In order to solve the limitations of functions and the use of traditional spectrum analyzer, a spectrum analyzer based on LabVIEW is designed in this paper. The spectrum analyzer design uses the modular programming ideas, including the signal module, filter module, time domain analysis and frequency domain analysis module. Through the test and analysis, the virtual spectrum analyzer designed in this paper can accomplish the analysis function of signal in time domain and frequency domain, which has the advantages of simple design and convenient operation. It can be used for experiment teaching.
