体育科研中多台测试仪器的同步方法──同步信号发生器的设计、制作及使用方法

Synchronous Method of Multiple Instruments in Sport Scientific Researches

同步信号发生器（简称同步器）是为体育科研专门设计和制作的。它主要用于体操、田径、球类及其它项目的测试研究中。同步器的设计原则是使课题研究用的各类仪器同步工作。同步器有6路信号输出端（分为A、B两组）和一个信号输入端，最多可使6台仪器同步工作。它的主要特点之一就是在多台测试仪器都处在正常（稳定）的工作状态中打出同步信号的时标（标记）。并且可以任意选择打标的时间。

A signal synchronizer was designed and made specifically for sport scientific researches. Synchroniz ing various instruments involving in a research,the device can be used in data measurementt of gymnastics, track and fieid,ball games and other events .with six signal output ends (Group A and B) and one signal input end,it can synchronize six instruments. One feature of this synchronizer was to be able to type the timescale of synchronous signals and choose the time of typing when all the insruments were in normal state.
