| 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. |

| Keywords: | atomic hydrogen maser phase locked loop frequency stability multiplier |
