td2700 multifunctional clock calibrator

用于脉冲计时、频率计数测试以及 gps 绝对时钟接收

特别适合于装置秒脉冲等时钟信号的检定与校准以及仪器授时

内时基年准确度高达 10 ppb

overview

td2700 is an instrument that can be used for pulse timing, frequency counting  and gps absolute clock reception. it is especially suitable for the verification and calibration of clock signals and instrument time giving. the annual accuracy of the internal time base is as high as 10 ppb. two methods can be adopted when the apparatus is used to verify the meter verification apparatus: 1. to output second pulse with accuracy up to 20 ppb. 2. to measure the frequency directly.
