摘  要:为满足电力电子变流技术实验课电压、电流波形观察的需要,利用示波卡和输入电路与Windows2000操作软件相结合,在普通计算机上实现了虚拟式双踪示波器。经实验课波形测试,证明该虚拟式示波器具有操作容易、功能全面、波形清晰、上、下线无共地的问题,所测波形既可储存,也可传输。因此虚拟式示波器的使用使波形观察的效果提高,实验报告的波形图更加规范和全面。In order to meet the requirement of both voltage and current waveforms being observed in the power electronics experimental course, the virtual oscillograph is put into effect, utilizing an oscillograph card, input circuit and Windows 2000 operation software, on a cormnon PC. The waveforms obtained by experimental test indicate that the virtual oscillograph have many advantages, such as its convenience in operation, function comprehension, waveform clear-out. Moreover, both the upper and lower lines have been upgraded their former defect of joint-earth. The waveform tested can not only be stored but also transferred. Therefore, the ability of the waveform observed is improved, as well as the waveform pictures of an experiment report is standard and comprehensive. All mentioned above attributes to the utility of this virtual oscillograph.
