无源网络的测试中出现了一些在单元件测试中所不存在的问题,以及自动电桥也提供不了测试所需要的速度。本文所讨论的一种快速的微计算机控制的导纳电桥是为克服上述问题和限制而设计的。前言随着无源网络(梯电阻、RC滤波器、数字集成电路汇流端等)的大量使用,提出了更行之有效的测试要求。当用机械手装置时,可在200到500毫秒内对网络上所有的外接点进行连接,网络测试的速度受到了对网络中的每对接点实现电子扫描与进行测量的时间的限制。
There were some problems that did not exist in the testing of passive components in the testing of passive networks, and the automation of bridges did not provide the speed needed for testing. A fast, microcomputer-controlled admittance bridge, as discussed in this article, was designed to overcome the above problems and limitations. Preface With the extensive use of passive networks (ladder resistors, RC filters, digital IC sinks, etc.), more effective testing requirements have been put forward. When using a robotic device, all external contacts on the network can be connected in 200 to 500 milliseconds. The speed of network testing is limited by the time required to electronically scan and measure each pair of contacts in the network.
