测试系统的自动化、智能化和通用化,使人们提出了这样一个问题:能否用一台计算机通过标准接口同时控制一组具有专门功能的通用测试设备呢?这就是美国惠普公司于六十年代末期所提出的积木化通用自动测试系统的概念,而所需要的标准接口就是IEC-625公布的GPIB(General Purpose Interface Bus)标准接口系统。单片机广泛应用于自动测试系统,目前国内较为通用的单片机是MCS-51系列单片机,因此,扩展51系列单片机的GPIB接口对于上述的
The automation, intelligence and generalization of test systems raise the question of whether it is possible to control a common set of test equipment with specialized functions through a standard interface using a single computer. This is how the Hewlett-Packard Company in the 1960s In the late stage, the concept of a universal automatic testing system for building blocks was proposed. The standard interface required is the GPIB (General Purpose Interface Bus) standard interface system published by IEC-625. Microcontroller is widely used in automatic test system, the current more common microcontroller is the MCS-51 series of single-chip, so to extend the GPIB interface 51 series MCU For the above
