IEC-IB(又称GP-IB或IEEE-488总线)是国际标准的通用接口总线系统,它在仪器仪表领域广泛应用,促进了第二代自动测试技术的迅速发展。近年来,已有越来越多的微计算机上配备了IEC-IB接口,使之能通过该标准接口系统控制多达十四台可程控仪器,灵活地组建各种自动测试系统,以实现可编程的连续测试、自动记录及数据处理。同时,由于接口系统采用了三线挂勾异步确认的通信方式,从而可在不同速度、不同系列的各种设备之间实现可靠的数据传输,这使IEC-IB接口不但可作为第二代自动测试系统的基础,而且有希
IEC-IB (also known as GP-IB or IEEE-488 bus) is an international standard universal interface bus system, which is widely used in the field of instrumentation, to promote the rapid development of the second generation of automatic test technology. In recent years, more and more microcomputers have been equipped with an IEC-IB interface that enables them to control up to fourteen programmable devices through the standard interface system and flexibly assemble various automatic test systems to achieve Programmed continuous testing, automatic recording and data processing. At the same time, as the interface system uses a three-wire hook asynchronously confirmed communication, so that in different speeds, different series of various devices to achieve reliable data transmission, which makes the IEC-IB interface can not only be used as a second-generation automatic test The basis of the system, but also hope
