【摘要】:介紹了一種具有快速硬件自觸發(fā)功能的數(shù)據(jù)采集前端的設計,針對大面積多探測點的高能宇宙線實驗的特殊情況,提出了獨立自觸發(fā)、數(shù)字化和數(shù)字濾波的實現(xiàn)方案。通過靈活的板級控制和兼容的PCB管腳設計,提供比較靈活的采樣速率和采樣精度的調(diào)整,以滿足不同的需求。通過不同濾波器參數(shù)設置,實現(xiàn)對不同干擾信號的排除,完成信號的有效探測。
[Abstract]:This paper introduces the design of a data acquisition front-end with fast hardware auto-trigger function. According to the special situation of high-energy cosmic ray experiment with large area and multiple detection points, the realization scheme of independent self-trigger, digitization and digital filtering is proposed. Through flexible board level control and compatible PCB pin design, flexible sampling rate and precision adjustment are provided to meet different requirements. By setting different filter parameters, the different interference signals can be eliminated and the signal can be detected effectively.
