基于LabVIEW的多功能虚拟示波器设计

Design of multifunctional oscilloscope based on LabVIEW

随着测控技术的发展,虚拟仪器成为当今发展的热点。示波器的设计就是其中的1个主要应用领域。示波器作为一种常用的电子测量仪器,在科研中有着十分重要的作用。主要利用LabVIEW软件平台,采用模块化思想设计了1个多功能虚拟示波器。该虚拟示波器除了具有普通示波器的功能外,还增加了参数测量、储存和打印等功能,通过实验表明该示波器显示波形运行可靠、性能良好,能适用于普通实验室正常的使用需求。

With the development of measurement and control technology, the virtual instrument becomes a hot spot of today＇s development. The design of oscilloscope is one of the main application areas. As a common electronic measurement instruments,oscilloscope is being a very important role in scientific research. In this paper a multi-function virtual oscilloscope is been designed based on LabVIEW. The virtual oscilloscope has the function of parameter measuring,storage and print, besides with the ordinary function. The experiment shows that the oscilloscope runs reliably with good performance, which can be used for ordinary laboratory with normal requirements.
