Design and implementation of multifunctional virtual oscilloscope based on LabVIEW

Jiang Li-ying

Abstract

Aiming at the problem that the traditional oscilloscope only can display or measure signal,a multifunctional virtual oscilloscope was designed by using graphic programming language of LabVIEW and the modular design though.It has basic function similar to common oscilloscope,and the same time,it has some merits such as signal measurement,signal operation,filtering processing and frequency spectrum analysis.The test of the virtual oscilloscope showed the system operation was reliable and the performance was good,which could meet the requirement of laboratory and scientific research.
