同步键控器是为水声、超声的理论研究、设备研制、试验和测量研制的实验仪 器。它有经过延迟和不经过延迟的方脉冲输出，脉冲的重复周期和宽度有很宽的调 节范围和较好的稳定性；开关电路有很高的键控量，频率响应好；仪器有五种工作状 态，能满足多种试验和精密测量的要求。本机体积小、重量轻，可交、直流供电， 操作简单，可供从事水声、超声和电子工作的科研、工厂、学校的实验室使用。
Synchronous key controller is for underwater acoustic, ultrasonic theoretical research, equipment development, testing and measurement of experimental equipment. It has a delay and without delay square pulse output, the pulse repetition cycle and width has a wide range of adjustment and better stability; switching circuit has a high key control, good frequency response; There are five instruments Working conditions, to meet a variety of tests and precision measurement requirements. The machine is small, light weight, can be handed over, DC power supply, easy to operate, for underwater acoustic, ultrasonic and electronic work of scientific research, factories, schools, laboratory use.
