时频测量高性能内插模块实现

Realization of high performance interpolation module for time-frequency measurement

精密时间间隔测量技术在许多重要领域都占据着十分重要的地位,本文实现了一种基于时间幅度转换法的高分辨力、高单次测量精密度、高采样率时间内插模块并应用于高精度时间间隔测量,其时间分辨力达到20ps以内,单次测量精密度优于8ps,采样率达到了8MHz。

High-Precision time measurement is a very important technique of many key domain. A high resolution, high single-shot precision and high sampling rate interpolation module which based on Time to Amplitude Conversion has been developed in this paper. The time resolution of the interpolation module has reached less than 20ps, the single-shot precision is better than 8ps and the sampling rate has reached 8MHz.
