摘要:

在对基于DDS技术的公共振荡器设计、高速数据传输设计以及基于数字测频技术改进等技术难点分析的基础上，论述了基于双混频时差法的时域频率稳定度测量方法。该方法可同时测量短期和长期频率稳定度，测量精度高，并可进行无间隙测量。

Abstract:

This paper analyses the technical difficulties in the design of the public oscil lator base d on DDS（Direct Digital Synthesizer） technology, the design of high data trans mission and the improvement of the digital frequency measurement technology. On this base,it discusses the time domain frequency stability measurement based o n dualmixer offset measurement method. This method can perform sho rtterm and longterm frequency stability measurement simultaneously and posse ss the high measurement accuracy and can undertake noclearance measurement.

Key words: digital frequency measurement technology frequency stability dual mixer offs et measurement method DDS no clearance measurement
