高精度可编程双脉冲产生器

A programmable precision dual pulse generator

介绍了一种用于高精度 TDC测试的双脉冲产生器 ,该产生器可提供 TDC所需的 start和 stop脉冲 ,两个脉冲之间的时间间隔有 1 4位精度 ,时间晃动小于 1 3 ps,可通过跳线选择不同的动态范围 (2 0 0、50 0、1 0 0 0、2 0 0 0 ns)。

A high precision pulse generator for TDC test was developed. It was found that the generator has 14 bit accuracy of time interval between start and stop output pulses with less than 13 ps jitter. 4 full ranges (200 ,500,1000 and 2000 ns) can be selected using ajumper.
