一、概述 1972年美国HP公司生产一台网络分析仪3570A,提出了一套标准接口与总线系统,定名为HP-IB。采用这种标准,任何厂家生产的任何型号的仪器,都可以用一条无源的标准总线电缆连接起来,并通过一个与计算机相配的接口(控制者接口)与计算机相连接,从而可以方便地构成所需的测试系统。若计算机内已装有此标准接口,则可省去控制者接口而直接用标准总线电缆连接。 HP-IB总线经过改进后,经美国电气与电子工程师学会(IEEE)及国际电工委员会(ICE)组织,制定 First, an overview In 1972 the United States HP company produces a network analyzer 3570A, put forward a set of standard interface and bus system, named HP-IB. Using this standard, any type of instrument manufactured by any manufacturer can be connected by a passive standard bus cable and connected to a computer through a computer-compatible interface (controller interface), which can easily be constructed Required test system. If the computer has been equipped with this standard interface, you can save the controller interface and directly with a standard bus cable connection. The HP-IB bus was developed and developed by the Institute of Electrical and Electronics Engineers (IEEE) and the International Electrotechnical Commission (ICE)
