摘　　要：介绍以DSP2407芯片为核心,采用专用峰值幅度采样保持电路,根据输入信号上升沿及峰值信息进行分析的多道核脉冲幅度分析器系统的原理和硬件结构。在合金分析及同位素密度成像系统中,采用本脉冲幅度分析器进行高速数据采集,取得了满意的效果。也可适用于其他核脉冲信号峰值幅度分析的场合。This paper introduces the principle and hardware structure of multi-channels of nuclear pulse range system which regards DSP2407 as the core chip and adopts the special-purpose peak value sampling and retaining circuit and analyzes according to rising of input signal along peak value inforrnation. In the alloy analysis and the formation system of image of isotope density. It has adopted the pulse range analyzer to gather the high-speed datas and obtained the satisfactory effects. It can also be suitable for other ranges of peak value of nuclear pulse signals and analysis.
