The crystal oscillator is a high stability and high precision resonant devices, used widely in various electronic measurement, radio communications, aviation, aerospace and other fields. In this paper, the crystal structure of the peripheral circuit parameters and matching perspective to discuss how to improve the accuracy of the crystal method. Our work gives out a peripheral circuit which can improve the accuracy of the crystal range of parameter through Multisim circuit simulation software. The experiments use the GSP-810 spectrum analyzer for the actual testing and verify the actual crystal oscillator circuit spectrum and the results more visually.
