摘要
可应用于大型物理实验及大规模科学工程中的时序系统已研制成功,其功能主板内嵌于一台工业控制机中,系统可输出多路时序脉冲,其周期、延时及脉宽均可步进调节。经一年多在线运行证实了该系统工作稳定可靠,定时脉冲前沿时间抖动小于5ns。详述了定时系统的软、硬件配置及运行实测结果。
A timing system with the main board embedded inside of industrial computer can be employed in large-scale physics experiment or/and scientific project. The period?timing delay and pulse width of every output pulse from the timing system can be changed step by step . The time jitter of pulse forward-edge is less than 5ns . This timing system has operated on line more than one year. The architecture of hard-wire and soft-wire of this system are described.
