摘　　要：在ICF软X光能谱仪诊断实验中,为了将能谱仪各通道输出的纳秒尺度测量信号在时间上精确关联,需要测试系统提供定时精度好于200ps多路一致的时标信号。为此研制了无源纯电阻8路功分器来提供时标信号,通过对其性能进行的测试,表明该功分器基本满足现有物理实验要求。同时对功分器的进一步改进进行了分析,提出了解决方案。An improved eight power splitter is designed and fabricated newly, which is crucial in the timescale system of soft X-ray energy dispersive spectrometer. The spectrometer is used in ICF laser facility to measure the evolution of soft X-ray spectrum, whose duration is only several nanoseconds. The synchronization and high bandwidth of signals produced by power splitter are tested, which shows the power splitter could meet the strict requirements of the experiments. The discussion of further improvement of power splitter are also presented.
