摘　　要：阐述了一种基于GPIB技术的计数器电路测试系统的实现。该系统以直观的方式测试出由74LS90组成的五进制计数器输出端的波形、相关参数以及在单脉冲触发下输出端状态转换表。为高校开设电子类实验提供了一种新的方法。This paper presents the realization of test system based on GPIB technology, and displays intuitively the graphics of wave- forms and state transition map of counter that are made up of 74KS90. Therefore this paper provides a new method for electronics experi- ments in university, because this mode predigested the course of experiments, and emphasizes on the understanding and analysis of the result of experiments.
