Aiming at the problem of traceability of time stamp server,the calibration system is designed and imple-mented,and the time deviation is measured.At the same time,the PCIe bus technology is used for time synchroni-zation and output.The results show that the average time deviation of the system is 4.66 µs,and the experimental standard deviation is 0.48 μs,which meets the calibration requirements.
