摘要
针对时频测量系统对时统信号的同步需求,设计一种高精度时频信号同步系统,该系统基于软时统技术,简化系统硬件,有效降低系统成本。同时采用无通信共视技术和时频生成技术,实现高精度时频同步信号输出,使系统同步指标从50 ns提升到6 ns。
Aiming at the synchronization requirement of time-frequency measurement system to time synchronization signal,a synchronization system of high-precision time-frequency signal is designed.The system is based on soft time synchronization technology,simplifies the system hardware and effectively reduces the system cost.At the same time,communication free common view technology and time-frequency generation technology are used to achieve high-precision time-frequency synchronization signal output,which improves the system synchronization index from 50 ns to 6 ns.
