Virtual instrument is the product of the development of electronic technology and computer technology; it will gradually replace the traditional electronic instruments. As a new instrument, virtual instrument is the product of the development of electronic technology and computer technology, and it is widely used in the application of virtual instrument. The development of analog electronic circuit virtual instrument is an attempt to promote and apply the virtual instrument to the experiment teaching process. This paper introduces the concept of virtual instrument and its system structure, and presents the research status at home and abroad. This paper expounds the working principle of virtual instrument system, and discusses the performance index of data acquisition card and virtual instrument waveform acquisition, waveform output and its key techno...
