摘　　要：指出高速脉冲取样的关键问题是多路样品信号读取,介绍一种多路扫描电路,包括通路门、多路模拟开关、逻辑控制电路和输出增益电路四部分,给出具体电路设计和硬件组成。计算机仿真的逻辑时序表明,扫描电路工作正常,通过增益放大后的输出可提供给数字示波器或虚拟仪器平台Labview真实再现被测高速脉冲波形。It is pointed out that the key problem of high-speed pulse sampling is multi-sample readout. In this paper a multi-scanning circuit is introduced, including pass gate, multiplexer, logic control circuit and output amplifier. Circuit design and the components of circuit are given. Logic sequence of computer simulation shows that the scanning circuit is in normal working order, the amplified output can be sent to digital oscillograph or Virtual Instrument Studio LABVIEW for the redisplay of measured pulse waveforms.
