High-precision and high-resolution time intervals are needed to improve high-precision measurement in time-frequency measurement system. The paper introduces the measurement technique and design of 1 ns time interval measurement, and analyzes the realization of analog interpolation and high-resolution precision time interval measurement. Research and analysis show that the analog interpolation method can not only meet the high-precision and high-resolution time difference measurement, but also improve the 1 ns time interval measurement.
