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。 Synchronous signal generator (referred to as the synchronizer) is designed specifically for sports science research and production. It is mainly used in gymnastics, track and field, ball games and other projects in the study of the test. The design principle of the synchronizer is to make all kinds of instruments used in the research work synchronously. Synchronizer has six signal output (divided into A, B two groups) and a signal input, up to 6 instruments can work simultaneously. One of its main features is the timing (marking) of synchronizing signals when multiple test instruments are in normal (stable) operation. And you can choose the marking time.
