【摘要】 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。更多还原

【Abstract】 In wide single high- speed pulse signal data acquirement system,a trigger signal with realiable stability and with little tingle delay time was required. In order to miniaturize facility application,this paper introduced 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 combination of the analog and digital circuits which had convenient interfaces and reduced the size of the PCB by using CPLD. The synchronizer was successfully applied to the fast pulse radiation detection.更多还原
