| 摘 要： | 论述了基于ＩＢＭ－ＰＣ机的超高速数据采集系统，提出了采用“闪烁”Ａ／Ｄ转换器超高速采样和分时分片多体存储技术的设计方案；简述了该系统的主要结构，由于合理地选用、分布超高速芯片（ＥＣＬ电路）和普通高速芯片，故只用少量的超高速芯片，即可满足系统的指标要求，又扩大了存储容量，提高了性能／价格比。可满足输入电压±（１０ｍＶ～２０Ｖ）双通道的示波系统模拟信号测量要求。

| Abstract: | This paper is concerned with an ultra-high-speed dual-channel data acquisition systemwith an input voltage of +(10 mV-20 V)and a sampling rate of 100 Msa/s. The design ofthe key unit circuits in the system has been successfully tackled.The flickering ADC ultra-high-speed sampling technique as well as the time-shared and memory-partitioned techniqueis used in the overall lavout. |
