Abstract :
Based on LabVIEW8.6 platform, this thesis developed a multi-function virtual oscilloscope system that includes the single channel oscilloscope which can realize the signal waveform display, time measurement, filtering and spectrum analysis of simulation signal, double channel oscilloscope which can realize the synthesis of Lissajous fingure by two signals and soundcard oscilloscope which using sound card as the data acquisition card, can realize the actual signal processing and complete the simulation signal measurement in±50V. This virtual oscilloscope completed basic signal analysis and processing, and can be used in the experiment teaching. In addition, using sound card as data acquisition card, it can complete the actual signal analysis, processing and storage. It has some advantages such as cheap price, convenient use and broad application prospect.
