Abstract:

At present,the phase noise of the crystal oscillator under vibration is required in electronic systems.The testing result can be abnormal according to the regular phase noise testing method for am anti-vibration crystal oscillator.The phase noise and testing method of the anti-vibration crystal oscillator under vibration was analyzed in this paper.In contrast to testing we find out some problems,that there can be the different testing result in the different test system.The test result can be according in the different test system,through system setting and experimental verification.

Key words: crystal oscillator;　phase noise;　anti vibration;vibration
