摘　　要：针对传统示波器只能显示和测量信号的问题,利用LabVIEW的图形化编程语言,采用模块化设计思想,设计了一款多功能虚拟示波器.该示波器不仅具有普通示波器的基本功能,还具有信号测量、信号运算、滤波处理和频谱分析功能.对虚拟示波器的测试结果表明,该虚拟示波器运行可靠、性能良好,能满足正常的使用需求.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.
