摘要
当今仪器发展的方向是在通用计算机平台上用软件实现传统测试仪器的功能,即虚拟仪器,文章引进这个概念并通过可行性研究给出了基于图形化编程语言LabVIEW而编写的虚拟仪器技术对频谱仪操作进行软件自动控制。运用LabVIEW的调用库函数功能将外部程序与LabVIEW相连接;运用事件结构技术,提高对仪器的控制速度;另外数据存储、频域分析技术,实现对原始数据文本文件和频谱图像的处理保存。
Today＇s development direction of instrument design is a kind of software that realizes the function of the classical test and measure instrurnent on the universal computer platform.It＇s virtual instrurnent,fatching in the conception of which to introduce the des- -ign of cortrol system for spectrum analyzer with graphical progrming language LabVIEW based on Virtual Instru- ment technology through feasibility study.The collection with external program and LabVIE＇W is realized by introducing Call Library Function technol- -ogy in LabVIEW.Using Event Structure technology is greatly improved the controll speed.Daling with and storing the raw data and the spectrum interface in files is obtained with LabVIEW＇s File I/O and analyses in the frequency dornains technology.
