多功能录呼机信号仪俗称“寻呼机发码器”,是对寻呼机进行维修、调试、改频的必需设备。有关这类仪器工作原理的文章却很少见诸于刊物,为此,笔者借贵刊给大家介绍一种多功能寻呼机信号仪的工作原理和使用方法。该仪器的型号为ML-18V3型。这种仪器又分为A型和B型两种,其主要区别是所采用的核芯器件(单片机)的型号不同,A型所采用的单片机型号为PS1008;B型为PIC16C54。二者相应的软件也有区别,但功能近似,使用方法基本相同。下面以ML-18V3的A型为例具体介绍如下:
Multifunctional pager signal instrument commonly known as “pager transmitter” is the necessary equipment for pager repair, commissioning, frequency conversion. Articles on the working principle of such instruments are rarely seen in journals, for which I author your magazine to introduce a multifunctional pager semaphore working principle and method of use. The model of this instrument is ML-18V3. This instrument is divided into two types of A and B, the main difference is that the core device used (SCM) models are different, A-type microcontroller models used for the PS1008; B-type PIC16C54. The corresponding software is also different, but the function is similar, the use of the same method. The following type A ML-18V3 as an example as follows:
