Research to technology of the frequency source under the state of noise vibration

The article discusses the theory and testing method about the time-domain characterization and the frequency-domain characterization, and purport of measuring frequency stability under the state of vibration .It also describes this established system and the operating principle of the measurement system in detail. Phase noise change curves and data aaa given at last, the economic and society benefits are analysed. The test results indicate that the system has a very low noise floor, small volume, simple operation, and its technical performance arrived lead level at home. It may not only measure characterization of frequency soyrce under the dynamic environment,but also be used for the lab and factory as universal measurement tool.
