总结了ASTRO-H （Hitomi）软x射线光谱仪脉冲形状处理器（PSP）的初始在轨性能结果。介绍了事件格式、遥测类型和脉冲处理参数，并列出了在轨参数设置。PSP在发射2天后开机，并在轨道上降低了事件阈值。PSP在轨道上工作良好，在航天器解体之前，既没有存储器错误，也没有SpaceWire通信错误。研究了时间分配、电相声和事件筛选标准。经验证，在100%中央处理单元负载下的事件处理速率为~ 200 c / s / array，符合PSP的要求。
We summarize results of the initial in-orbit performance of the pulse shape processor (PSP) of the soft x-ray spectrometer instrument onboard ASTRO-H (Hitomi). Event formats, kind of telemetry, and the pulse-processing parameters are described, and the parameter settings in orbit are listed. The PSP was powered-on 2 days after launch, and the event threshold was lowered in orbit. The PSP worked fine in orbit, and there was neither memory error nor SpaceWire communication error until the break-up of spacecraft. Time assignment, electrical crosstalk, and the event screening criteria are studied. It is confirmed that the event processing rate at 100% central processing unit load is ∼200 c / s / array, compliant with the requirement on the PSP.
