虚拟仪器是现代测量技术和计算机技术相结合的产物，标志着自动测试与电子测试仪器领域技术发展的一个崭新方向． 随着信息技术和计算机技术的高速发展，数字信号处理作为一门新兴的学科，其重要性日益在各个领域的应用中体现出来。本文介绍了利用LabVIEW 图形编程语言进行虚拟仪器开发的方法，设计了一种基于PC机声卡的虚拟示波器，说明了虚拟仪器在现代测试领域中的重要地位以及其广阔的发展前景． 从某种意义上说，“软件就是仪器”。(Virtual instrument is the produce that merges the computer technology and measurement technique．It stands for a brand new development directory in the field of auto-measurement and electronic measurement。 With the rapid development of information technology and the computer technology, the digital signal processing takes an emerging discipline, its importance displays day by day in each domain application. This article introduces how to develop virtual instruments using graph programming language-LabVIEW ,designs a virtual signal displayer based on PC and explains the important part and wide development prospects of virtual instrument in modern measurement technique field． In a sense, “The software is an instrument”.)

采用虚拟仪器LabWindows/CVI软件平台开发了基于PCI-6221多功能数据采集卡的实时频谱分析仪。(Virtual instrument LabWindows/CVI software platform based on real-time spectrum PCI-6221 multifunction data acquisition card analyzer.)

简单地报表生成程序，包含了文字 表格 曲线图，是很好的学习资料(Simple report generation program includes a text table curve, is a very good learning materials)

适合多界面开发，可实现多窗口运行,丰富界面显示。(Suitable for multi-interface development, can achieve multi-window operation, rich interface display.)

运用Labview进行虚拟示波器串口设计的源码(The use of Labview virtual oscilloscope serial design source)

虚拟振动测试仪，基于labview环境下开发的，用于对设备的振动分析(The Virtual Vibration Tester)

利用VISA去控制GPIB串口通信，最终实现与频谱仪，电源，示波器等相互之间通信(VISA to control GPIB serial communication, and ultimately with the spectrum analyzer, power supplies, oscilloscopes, and other mutual communication between)

利用labview操作者框架写的模拟串口通信，非常不错。(The analog serial communication written by the labview operator framework is very good.)

说明：  一本很不错的英文LabVIEW书籍，详细阐述了labview的设计思想和范例。(a very nice book talking about how to design a good LabVIEW program.)
