INTRODUCTION
The PC based virtual instrumentation is a dynamic and attractive to the classic instrumentation.Its main advantages are:flexibility and adaptability (it can be easily expanded and reconfigured for different applications),low cost,wide development of extension PC boards with measurements features,attractive representation of measurement results,in different forms,on the PC’s monitor.There are several typical areas for PC based instrumentation such as:data acquisition and analysis,signal monitoring,automatic testing,quality assurance,education,etc.
Important achievements for educational purposes are reported in the literature.Many companies produce virtual instrumentation and many projects are developed in various universities to provide higher level and lower cost solutions for laboratory component of courses on instrumentation and measurement.A virtual instrumentation system is made of two components:a software part,usually based on Matlab or LabVIEW,and a hardware platform which is implemented by a PC extension board.The integrated measurement tool presented in relies on Matlab as a software component running on a DSP based system as hardware platform.Reference describes another approach,namely the inclusion of hardware and software measurements features into processor architecture.The approach and results are described using a Xilinx device with a MicroBlazeTM 32 bit architecture.The concept of RTNI (Real Time Non-Intrusive) instrumentation was applied to embedded systems.In another virtual instrumentation system is presented.The programs were written using National Instruments data acquisition hardware interface.
The present paper describes an educational PC based (virtual) instrumentation application for system identification.The virtual system is made of an external board,connected to the PC via the USB interface,a software tool,Agilent VEE (Visual Engineering Environment) and the software application.Agilent VEE is a visual tool used especially in measurement instruments and data processing and analysis applications.It offers help for configuring the instrumentation,developing user interfaces and simplifies the creation of needed applications.Agilent VEE offers support ActiveXControls increasing the applications functionalities.The presented virtual system can work as a voltmeter,ammeter,signal generator,digital oscilloscope and power supply.It was foresight with Internet and LAN capabilities.

介绍
被建立虚拟的使用仪器的个人计算机是一动态的和吸引人的对第一流的使用仪器. 它的主要利益是: 柔性和适应性 (它能为不同的申请被容易地扩大而且再配置) ,低成本 , 和测量特征,测量结果的吸引人表现的延长个人计算机董事会的广泛的发展, 以不同的表格, 在个人计算机的监视器上. 为被建立使用仪器 , 像是 : 的个人计算机有一些典型的区域 数据获得和分析,信号监听,自动机械测试,质量保证,教育, 等等.
对于教育的目的重要成就在文学被报告. 许多公司生产虚拟的使用仪器,而且许多计画在各种不同的大学被发展在使用仪器和测量上为课程的实验室成份提供比较高的水平和比较低的费用解决. 一个虚拟的使用仪器系统是用二个成份做成的: 一个软件部份, 通常基于 Matlab 或 LabVIEW, 和被个人计算机延长董事会实现的一个硬件月台. 被呈现的整合的测量工具在仰赖 Matlab 当做软件成份跑在一个数传信号处理器上被建立系统当做硬件月台.叁考描述另外的方式,即硬件的包含和软件测量进入处理器建筑学之内扮演重要角色. 方式和结果被描述和 MicroBlazeTM 32 一点点建筑学一起使用一个 Xilinx 装置. RTNI(真正的时间非打扰的) 使用仪器的观念被申请埋入系统. 在另外的一个虚拟的使用仪器系统被呈现. 计画被写使用国立器具数据获得硬件接口.
现在的纸描述被建立 (虚拟的) 使用仪器系统确认的申请的一个教育的个人计算机.虚拟的系统是用在经由万用串列总线接口,一个软件工具, Agilent V字形 (视觉的工程环境) 和软件申请被连接到个人计算机的外部董事会做成的.Agilent V字形是尤其被用于测量器具和数据处理和分析申请的一个视觉的工具. 它为配置使用仪器提供帮忙, 发展使用者接口而且单一化需要申请的创造. Agilent V字形提议支援增加申请功能性的 ActiveXControls . 被呈现的虚拟系统能运作如一个转变方向,安培计,信号产生器, 数传示波器和力量补给. 它用英特网和区域网络能力是远见.
