用于ZEEMAN频率测量的数字合成器

Digital freguency synthesizer used with ZEEMAN frequency measurement

ZEEMAN频率是氢脉泽时间频率标准的一个重要工作参数,为此上海天文台研制了一种专用的数字频率合成器,用来测量ZEEMAN频率。描述了该数字频率合成器的工作原理、设计方法和应用结果,该数字合成器,就配备在上海天文台新研制成功的氢脉泽标准而言,以其性能与价格而论,证明是成功的。

The ZEEMAN frequeney is one of important working parameters of hydrogen maser frequency standards, so a special digital time and frequency synthesizer, which is used to measure ZEEMAN frequencies, was developed. This paper will describe the operation principle, the design method and the application results of this unit.
