仪器无关测试系统IVI配置文件的管理

Management of IVI Configuration File in Instrument Indepen dent Test System

介绍了可互换虚拟仪器 (IVI)系统结构和运行机制。为了实现硬件无关性测试系统设计 ,IVI引入了分类驱动程序 ,可以对一类仪器进行操作。分类驱动程序与仪器的通讯由IVI引擎、具体仪器驱动程序、系统配置文件辅助完成。详细分析了IVI系统配置文件的信息组成。

This paper introduces IVI Architecture and run ning mechanism of IVI dr iver. IVI system introduces class driver to communicate with one kind of instrum ents for attaining the design of hardware-independent test system. Class driver communicate with instruments through the IVI engine and IVI configuration file a nd specific-instrument drivers. Then, the article analyses in detail the informa tion in the IVI system configuration file, method of using multiple configuratio n and the way to create run-time configuration information.
