一微电脑在外国已广泛应用于通信设备,从而起引国内各方面的重视,我们试制的微电脑单边带接收机控制器就是这方面的一个尝试。该机采用了INTEL 8085作为cpu,8255作为I/o口,由电平转换器与接收机频率合成器接口,并配有专用软件,直接由键盘控制接收机工作。它具有直接置频、定频、预置、修改、点扫、连扫、随时改变扫描速度及暂停等功能,使用方便灵活。本文简述该控制器部分的主要功能、实施方案及使用方法。
A microcomputer in foreign countries has been widely used in communications equipment, which cited all aspects of domestic attention, our trial of the microcomputer sideband receiver controller is an attempt in this regard. The machine uses the INTEL 8085 as cpu, 8255 as I / o port, by the level converter and receiver frequency synthesizer interface, and is equipped with special software, directly from the keyboard to control the receiver. It has a direct frequency, fixed frequency, preset, modify, point sweep, with sweep, change the scanning speed and pause at any time and other functions, easy to use and flexible. This article briefly describes the main part of the controller functions, implementation and use of methods.
