摘　　要：时间测量手段有很多种,基于脉冲间隔的时间数字转换(TDC)技术是其中重要的一种。高精度的TDC在诸如粒子飞越时间测量、雷达测距、激光测距、无线电测向等领域有着广泛的应用。文章介绍一种基于VXI总线寄存器基的8通道高精度大动态范围的TDC模块的设计实现。经刻度测量,模块精度达到500ps,测量动态范围大于32μs。实现了大动态范围条件下的多通道高精度TDC。There are many ways to measure time.Although,Time to Digital Converter(TDC)of pulse duration is an important method.High resolution TDC is widely used in nuclear experimentation,radar and laser range detection etc.It is introduced the design and implementation of an eight channel wide range and high resolution VXI register based TDC module.The resolution of the TDC is 500 ps and the dynamic range is longer than 32 μs.Multi channel large dynamic range high resolution TDC is implemented.
