基于PCAS的Tektronix示波器与EPICS通信研究

摘要

现代大型实验物理和加速器装置中,高端示波器被越来越广泛地应用于信号采集和测量方面.EPICS是应用于大型实验物理和加速器控制系统的组态软件工具集,PCAS是EPICS用来端接EPICS异构系统的一种手段,已在多个加速器和EPICS工具上得到应用.论文介绍了利用PCAS把Tektronix示波器接入EPICS的方法.基于该方法,实现了通过EPICS对BEPCⅡ电子枪触发信号抖动值的实时监测.%High performance oscilloscopes are more and more applied to modern large experiment physics and accelerator facility for signal acquisition and measurement. EPICS is a tool set applied to experiment physics and accelerator facility control system, PCAS is a means to port non - EPICS system to EPICS and has been applied to many accelerator facilities and EPICS tools. A method of porting Tektronix oscilloscope to EPICS using PCAS is introduced in the paper, and a real - time monitoring system for jitter measurement of BEPCII electron gun trigger signal has been realized based on this method.
