基于LabVIEW的虚拟示波器的设计

本文以LABVIEW为开发平台,构建一个与计算机硬件资源紧密结合的虚拟仪器系统。由虚拟信号源激励的虚拟示波器,可以满足一般测量的要求,并且波形显示效果都很好。在研究中发现LabVIEW程序可以很方便地控制声卡,因此考虑到可以以声卡为信号源,进行另外一款虚拟示波器的开发,于是设计实现出了一款利用声卡进行数据采集的虚拟示波器,整体效果良好。

Design of Virtual Oscilloscope Based on LABVIEW

In this paper , to build a virtual instrument system connection closely with the computer hardware by LABVIEW. Virtual instrument to the traditional instruments of specialized features and software of the control panel so that the computer constitutes a combination of function the same as with traditional hardware equipment, while at the same time take full advantage of the new computer hardware and software resources of the virtual instrument system, which perfect solution to the shortcomings of traditional instruments, so the use of NI laboratory LabVIEW virtual instrument development platform for the development of a virtual oscilloscope.
