一、概述英国Solartron公司生产的1172型超低频频响特性分析仪,采用了先进的程序控制。测量过程应用了数字计算机技术,为实现实时、多路、遥控创造了条件。使用大为方便,范围更加扩展。据悉,已进口多台,但是由于该仪器技术说明书,对控制程序电路部分说明简略,给我们学习和掌握该仪器,带来了一定的困难。本文根据个人的理解,简述控制逻辑电路和若干程序,主要以控制程序的产生为主,并以流程图形式,例举说明几个主要程序。至于该仪器其他电路的说明,请参阅该仪器说明书和电路图,也可参考“一种程序测试仪——1172型频响分析仪电路原理分析的补充说明”一文。二、控制逻辑电路原理简介这部份电路包括原说明书电路图第58图至第65图,还有第56图上的操作译码器和运算状态多路器。以下就58至65图简述其功用。
First, an overview of the British company Solartron 1172 ultra-low frequency frequency response analyzer, using advanced program control. The measurement process uses digital computer technology, creating the conditions for real-time, multi-channel, remote control. Great use of convenience, the scope is more extended. It is reported that more than one has been imported, but due to the technical specification of the instrument, a brief description of the circuit of the control program has given us some difficulties in learning and mastering the instrument. This article based on personal understanding, a brief description of the control logic circuit and a number of programs, mainly to control the production process-based, and the flow chart form, illustrates a few major programs. As for the other circuit description of the instrument, please refer to the instrument manual and circuit diagram, but also can refer to “a program tester - 1172-type frequency response analyzer circuit theory analysis supplementary note” article. Second, the control logic circuit principle Introduction This part of the circuit, including the circuit diagram of the original instructions 58 to 65, as well as 56 on the operation of the decoder and computing state multiplexer. The following is a brief description of its function from 58 to 65.
