摘　　要：在脉冲辐射测量中,为了获取精确的辐射脉冲面积谱需要完整的脉冲信号信息,针对普通数字化多道无法实现直接对辐射探测器输出的脉冲信号进行完整采集,介绍了一种快速准确有效的辐射脉冲信号面积谱获取方法。通过结合高采样高带宽率数字示波器和仪器远程控制、数据采集处理上位机软件,可实现对高计数率、高宽带的脉冲信号实现自动采集,并利用软件批处理的方式实现数据的重建和面积信息获取,最后完成脉冲信号面积谱的自动统计生成,可大大提高辐射脉冲测量工作的效率。In order to acquire the acreage energy spectrum in activity radiation detection ,the full information of the pulse signal was needed .This paper introduced an available and fast measurement method based on digital oscillograph , because the common MCA system could not straightly disposes the pulse signal from the detector . It achieved the full signals waveforms automatic acquirement with high -sampling and high-bandwidth digital oscilloscope by instrument -control software .At last it statistically traced out the acreage energy spectrum with the information of each pulse signal which was gained by the batch program .It could highly improve the work ef-ficiency of the radiation detection .
