摘要
介绍基于LabVIEW的虚拟示波器的设计,它是由数据采集卡采集外部信号,通过软件编程来实现仪器的显示及测量等功能。该虚拟示波器主要由数据采集、数字滤波、参数测量、频谱分析、功率谱分析和波形存储及读取模块组成,具有传统仪器所没有的许多优点,如能保存波形及测量结果、成本低廉,可以根据需要进行功能拓展等。实验证明,该虚拟示波器运行可靠、性能良好和结果正确。
This paper introduced the design of virtual digital oscilloscope which is based on LabVIEW.It adopts the data acquisition card to get external data,and realizes the display and measurement and other functions through software programming.The virtual oscillograph consists of data acquisition,digital filtering,parameter measurement,frequency spectrum,power spectrum analysis and wave storage modules.It has many advantages,such as saving wave form and measuring result,costing lower and extending function when n...
