虚拟示波器的设计与实现

Design and implementation of the virtual oscilloscope

通过虚拟仪器软件LabVIEW,在PC机上架构虚拟示波器,借助数据采集卡实现电路信号的采集传输,并充分利用虚拟仪器软件对信号的分析、处理、测试等功能,实现并得到了包括毫伏表、频率计功能在内的虚拟双踪示波器.

In this paper the authors build a virtual oscilloscope on PC by the virtual instrument software LabVIEW for signal analysing, processing, testing, etc. The data acquisition card is used to get circuit signals and data are read into the computer, therefore the functions of this virtual dualtrace oscilloscope such as the mV meter, Frequency meter are realized.
