一种全面响应时间的频率稳定度测量
Method of a comprehensive response time of frequency stability
摘要
Abstract
To reveal the change of the frequency stability of a different frequency source with the response time in essence,a method of measuring the comprehensive response time of frequency stability is proposed. In the digital environment,the digital edge effect is used to inhibit the quantization error,combined with the digital double mixing time difference method to measure the phase difference between the signals,by which the comprehensive frequency stability index is obtained.In experiments,the frequency source realizes the frequency stability of a more comprehensive change rule over time. Experiment proves that the method under the condition of self-calibration, transient frequency stability can be 10 —5/100 ns, that short-term frequency stability can be 1012/s,and that frequency stability for a long time can be 1016a day.关键词
