摘　　要：石英晶体谐振器电参数是石英晶体的主要技术指标,其测量方法有多种,基于π网络法石英晶体谐振器电参数测量原理,根据π网络分布参数对测量精度的影响,在测量电路中进行了硬件补偿;在理论分析的基础上设计和制作了π网络法石英晶体谐振器电参数测量电路,介绍了主要单元电路的设计,实现了石英晶体谐振器电参数测量并将测量系统应用于石英晶体频率微调设备中。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.
