【摘要】 针对目前基于计数器的传统时间频率采集系统采样间隔不精确，时频测量数据性能分析功能单一且无法实现参数指标实时分析、显示的问题，本文介绍了一种基于动态反馈控制算法生成精准时间戳的时间间隔测量方法，并将采样间隔的动态补偿与时间戳累积误差校准进行有效结合。同时，为实时分析显示计数器测量结果与数据图像，设计开发了一款改良型时间频率测量分析系统，并给出实时性能指标分析。更多还原

【Abstract】 In response to the problems of inaccurate sampling intervals, single performance analysis functions for time-frequency measurement data, and inability to achieve real-time analysis and display of parameter indicators in traditional counter based time-frequency acquisition systems, this paper introduces a time interval measurement method based on dynamic feedback control algorithm to generate accurate timestamps, and effectively combines dynamic compensation of sampling intervals with accumulated timestamp error calibration.At the same time, an improved time-frequency measurement and analysis system was designed and developed for real-time analysis and display of counter measurement results and data images, and real-time performance indicator analysis was provided.更多还原
