设计了一个8通道的脉冲波形分析器。此系统以双现场可编程门阵列(Field Programmable Gate Array,FPGA)为核心,板载大容量同步双端口随机存取存储器(Random-Access Memory,RAM),并行8通道96 MHz高速采样模数转换器(Analog-to-Digital Converter,ADC),能够同时对8路脉冲波形进行采样分析,得到脉冲时间间隔谱、脉冲幅度谱和脉冲宽度谱。该设备ADC以10.4 ns的采样间隔采集脉冲数据,通过通用串行总线(Universal Serial Bus,USB)2.0与电脑实现数据上传,并借助上位机进行数据的实时显示。该设备已成功运用于硬X射线调制望远镜(Hard X-ray Modulation Telescope,HXMT)卫星高能主探测器的电性测试,并能够广泛适用于核辐射研究领域。
Designed an 8-channel pulse waveform analyzer. The system uses a field programmable gate array (FPGA) as its core. The system has an on-board high-capacity synchronous dual-port random access memory (RAM) and an 8-channel 96 MHz high- An analog-to-digital converter (ADC) can sample and analyze 8 pulse waveforms at the same time to obtain the pulse time interval spectrum, the pulse amplitude spectrum and the pulse width spectrum. The ADC collects pulse data at 10.4 ns sampling intervals, uploads data to a PC via Universal Serial Bus (USB) 2.0, and displays data in real time using a host computer. The device has been successfully applied to the electrical test of the HXMT satellite high-energy main detector and can be widely applied in the field of nuclear radiation research.
