基于VC++的虚拟示波器的设计与实现

he virtual instrument introduced in this article is a multi-purpose virtual digital oscilloscope based on VC++ and the DAQ card. As a result of the superb object-oriented programming characteristic of the VC++, this virtual oscilloscope can display its formidable function, such as data acquisition, data analysis as well as the display of the waveform and so on. There are several function modules such as data acquisition, waveform analysis, data measurement on this virtual oscilloscope control panel. Compared with the traditional oscilloscope, this system has the characteristic of simple structure, low development cost and convenient realization. Combining the outstanding interactive performance between each module, it can meet different users\
