The Calibration Method of Time Code Equipment

Abstract

Time code is widely used in television broadcasting systems, power, and aerospace. Time synchronization accuracy is an important indicator of each time code equipment, and the measurement and calibration of time code equipment is mainly the measurement and calibration of the time synchronization accuracy and time information of each time code. Based on the portable time code measuring instrument, the working principle and basic characteristics of the portable time code measuring instrument are analyzed, the measurement method and measurement principles of 1PPS, B(DC) code, B(AC) code and other time codes are introduced, and the calibration method of 1PPS, B(DC) code and B(AC) code are discussed.
