针对光电倍增管(Photomultiplier Tube,PMT)批量测试实际需求和单光电子谱精确测试光源的要求,通过对光电倍增管性能测试系统进行分析,设计制造了一种多通道输出可调的脉冲信号发生器的控制板,可用于光电倍增管单光电子谱的性能测试。该脉冲信号发生器在上升时间、下降时间等参数性能方面优于目前测试系统采用的商用信号源RIGOO-DG5352 350 MHz。用此脉冲信号发生器对光电倍增管进行单光电子测试,其输出信号能满足单光子测试的基本要求,利用其多路信号输出的特点,通过性能扩展即可用于光电倍增管的批量测试。
In order to meet the actual demand of batch test of Photomultiplier Tube (PMT) and the requirement of single photon spectrum for accurate test of light source, a multi-channel output pulse signal generator with adjustable output is designed and manufactured by analyzing the performance test system of photomultiplier tube Of the control panel can be used for photomultiplier tube single photoelectron spectroscopy performance test. The pulse signal generator is superior to the RIGOO-DG5352 350 MHz commercial signal source currently used in test systems for parameter performance such as rise time and fall time. With this pulse signal generator, the photomultiplier tube is tested by single-photon. Its output signal can meet the basic requirements of single-photon test. With its multi-signal output characteristics, it can be used for the batch test of photomultiplier tube through the performance expansion.
