Ai Ling Qu, Hong Mei Liu, Yan Lv, Ru Kun Han, Qiu Yan Liang

Abstract

The virtual instrument is the computer-based instrument. The close integration between computer and instrument is one important instrument development direction. The virtual digital storage oscilloscope introduced in the paper has some additional functions except the common oscilloscope functions, its additional functions are spectral analysis, parameter automatic measurement, complex conditions trigger and data storage. The virtual digital storage oscilloscope communicates with the PC software through USB port. The paper discusses the overall design ideas of virtual digital storage oscilloscope, and the composition and functions of the circuits.
