Design of the electrical parameters measurement circuit of quartz crystal

There are many kinds of methods of measuring electrical parameters as the main technical index of a quartz crystal.A kind of measurement principle of quartz crystal parameters in the π network is introduced.Impacts on the measurement accuracy of distributing parameters of the π network are analyzed theoretically and the hardware compensations are made.The measurement circuit of the π network is designed and produced based on the theoretical analyses.The design of main circuit units is introduced.It can measure electrical parameters of a quartz crystal and be used in the quartz crystal plating system.
