摘　　要：介绍了基于GPIB总线技术和16台泰克TDS694或684数字示波器组成的64通道高速波形采集及分析系统,研制了多路精密同步触发系统,同步精度好于200ps,开发了可视化的WINDOWS仪器控制和数据处理程序。系统可对波形特征信息自动判读,并对系统误差进行修正,整个系统的时间间隔测量的标准不确定度为0.5ns。This paper introduces a new system for 64 channels high-speed waveform acquiring and analysis based on GPIB bus technique. A Multi-channel trigger subsystem provides 200ps synchronization precision. A visual instruments control and process program under windows for the system was developed, and automated waveform characteristic processing was realized. After correcting system error, the standard uncertainty of time interval measurement of whole system is 0. 5ns.
