摘要
本文设计和实现一种基于LabVIEW的虚拟示波器设计,主要利用基于USB接口的MSP-010501数据采集卡,通过LabVIEW软件的编程完成系统软件与数据采集卡之间的通信。软件总体包括通道选择、触发控制、时基幅值控制、波形显示、电压测量、相位测量、功率测量等模块,最终实现开发一个能够对多种控制参数进行设置、实时采集、处理、显示的虚拟示波器。
The design and implementation of a virtual oscilloscope based on LabVIEW is introduced in this paper.By using the data acquisition card MSP-010501 based on USB interface and the programming through LabVIEW software,the correspondence between the system software and the data acquisition card is implemented.For the implementation of the virtual oscilloscope which is capable of the setting-up,real-time acquisition,processing and displaying of several controlling parameters,the software is designed to be composed of the modules of channel choice and triggering control,time sweep velocity and amplitudes control,waveform display,voltage measurement,phase measurement and power measurement.
