单次快脉冲锁存同步机研制

摘要

In wide single high-speed pulse signal data acquirement system , a trigger signal with realiable sta-bility and with little tingle delay time was required .In order to miniaturize facility application , this paper intro-duced a multi output synchronizer which offer the fast reliably signal which could be latched with a longer time . Additionally , the width and the delay time of the signal could be accurately adjusted .It designed by the combi-nation of the analog and digital circuits which had convenient interfaces and reduced the size of the PCB by u -sing CPLD.The synchronizer was successfully applied to the fast pulse radiation detection .%在大动态单次快脉冲高速数据采集系统中，需要稳定、可靠、延迟抖动小的触发信号。本着小型化的目的，本项目研制了一套单次锁存多路同步机，为前端数字化提供延迟可调、脉宽可调、锁存时间长的触发信号。该仪器采用模拟电路和数字电路相结合，基于复杂可编程逻辑器件（ CPLD）大大减小了电路板的设计尺寸，接口方便，在辐射快脉冲信号探测中得到较好应用。
