| 摘 要： | 介绍了一种基于FPGA的8通道高速定时计数器的NIM插件的设计原理与实现.电子学测试表明该插件能够响应最小脉宽为2ns的脉冲输入,最高计数率达到170MHz,定时精度为100ns.插件可以在联机和脱机两种模式下工作:联机工作模式下,PC机通过USB接口控制插件工作,实时地在主机上采集和显示各通道计数状态,并支持多个相同设备的热插拔;脱机模式下,可通过本地面板控制插件工作及显示各通道计数值.

| Abstract: | The design and implementation of an 8-channel high-speed counter and timer module based on FPGA technology and with USB interfacing are discussed.The module has been tested,the test results present that its minimum input pulse-width is 2 ns,the maximum counting rate is 170 MHz and the timing precision is 100 ns.The module can work in online mode or offline mode.In online mode,the current counting results of every counting channel can be displayed in real time on PC;the PNP of multi modules is supported.In offline mode,its front panel can control the module to achieve measurement results. |
