Multichannel amplitude analyzers : standards for time - to - amplitude converters 多通道振幅分析器.时间-振幅转换器标准
Moreover because the detector output pulse signal base is very broad , its scope has a long tail , it can not adapt to request of the multichannel pulse amplitude analyzer 另外由于探测器输出脉冲信号底部较宽,脱尾严重,不能满足多道脉冲幅度分析器的要求。
The thesis introduces the hardware and software design skills of a new type multi - channel pulse amplitude analyzer ( mca ) based on fpga chip and enhanced parallel port ( epp ) interface 本文从硬件和软件两方面详细地介绍了以fpga芯片为控制核心的基于epp接口的新型多道脉冲幅度分析仪的研制过程。
The pulse neutron generator " s delaying time are measured by the time - amplitude converter and multichannel pulse amplitude analyzer . according to these times , the linear gate circuit " s opening time can be adjusted 用它和多道脉冲幅度分析器配合测量脉冲中子发生器发射中子的滞后时间,据此调整线性门电路的开门时间。
At present the identification signal of rolling bearing is based on analog monitoring system composed of analog instrument such as fft analyzer , amplitude analyzer and so on . the system has the shortcoming as follows : not enough friendly user interface , unitary function , under abundant analytical contents , poor generality , long developing period , high cost and so forth 目前对滚动轴承信号识别主要采用模拟监测系统,系统均由模拟量仪器组成,如fft分析仪、幅值分析仪电平记录仪等,系统存在操作界面不够友好,功能单一,分析内容欠丰富、通用性差、开发周期长、成本高等缺点。
