摘要/Abstract

摘要： 主动型原子频率标准如氢脉泽具有目前最优秀的频率稳定度,然而氢脉泽源产生的信号不能直接应用.本文主要介绍将氢脉泽源性能传递到一个标准晶体振荡器的一种相位锁定技术.

关键词: 频率稳定度, 倍频器, 氢脉泽, 相位锁定

Abstract: Active atomic frequency standards, such as hydrogen maser, are characterized by a very good frequency stability. However, they deliver a signal at a power level and at a frequency that are not practical to the users. This paper descries the techniques used to phase lock to the hydrogen maser a standard crystal oscillator at a cardinal frequency.

Key words: atomic hydrogen maser, multiplier, frequency stability, phase locked loop
