摘　　要：以单片机89S8252为核心，开发了一种可以远程控制的多路数字延迟脉冲发生器。其主要输出参数为：重复频率1～1000Hz可调，时间延迟0～60ms可调，精度分为1“s和0．1μs两种，发生器输出脉冲可以直接驱动多路可控硅，工作方式分为远程控制和外部触发两种。该发生器已用于高功率微波驱动源的控制中，抗干扰能力强，工作可靠。A remotely controlled pulse generator was developed with SCM 89S8252 as CPU. It has an adjustable repetitive rate of 1-1 000 Hz, an adjustable time delay of 0-60 ms, a step value of μs or 0.1 /2s. Its output pulses can directly drive SCR. It can be controlled either by a remote computer or an external trigger mode. Experimental results indicated that the generator worked well against the electromagnetic interference caused by the pulse power system.
