一、简介随着大量采用无源网络(阶梯电阻器、滤波器、数字集成电路总线末端负载等),就产生了如何有效地予以测试的问题。使用机械处理器,能在200～500毫秒内对网络的全部外接点进行连接,而对网络的测试速度则受到对网络每对点子的电子搜索和进行测量所需的时间的限制。继电搜索通常能在5～10毫秒内完成,而一般的自动电桥,则能够在250～1000毫秒内完成测量。这一测量速度对于测试单独部件,通常是够快的。但是,当被测网络
I. INTRODUCTION With the mass adoption of passive networks (ladder resistors, filters, digital bus loading at the end of the bus, etc.), there has been a problem of how to efficiently test it. With a mechanical processor, all external points of the network can be connected within 200-500 milliseconds while the speed of testing the network is limited by the time required to electronically search and measure each point of the network. Relay search can usually be completed in 5 to 10 milliseconds, while the general automatic bridge, it can be completed within 250 ~ 1000 milliseconds. This measurement speed is usually fast enough for testing individual components. However, when the network under test
