摘要

基于 LabVIEW 的虚拟示波器可以实现波形的双通道输出、显示各种基本波形以及李萨如图形，观察频率、相位等参数对波形的影响，测量未知信号的频率和相位差，将波形图和实验数据以图片形式进行保存。这种虚拟双踪示波器操作简单、功能多样，将其应用于医学物理实验，可以使实验操作简单化、直观化，提高实验效率。

Abstract:

The virtual oscilloscope based on LabVIEW can realize the dual channel output of waveform，display various basic waveforms and Lissajous figure，observe the influence of frequency，phase and other parameters on waveform，and measure the frequency and phase difference of unknown signals．The waveform and experimental data are saved in the form of picture．This virtual oscilloscope is simple in operation and has various functions．The experiment operation is simplified and visualized and the experiment efficiency can be improved．

Key words: LabVIEW virtual oscilloscope
