摘　　要：　在分析与对比三种测量石英晶体元件负载谐振频率方法的基础上,设计适用于测量法的π网络与整个测量系统,采用自动网络分析仪测量晶体的阻抗,采用测量法测出负载谐振频率.实验表明,在1MHz～200MHz频率范围内,系统对负载谐振频率重复测量一致性能达到±1×10-6以内,在30MHz～200MHz频段,测量误差达到±2×10-6以内.Based on analysis and comparing three methods for measuring load resonant frequency of quartz crystal units, a π network and its proper measurement system is designed. Automatic network analysis method is used to measure the impedance of quartz crystal units, and ＂measured＂ method is used to measure load resonant frequency. It was proved that the measurement repeatability of the whole measurement system is less than ±1×10^-6 in frequency domain ranging from 1 MHz to 200 MHz, and the measurement error is less than ±2×10^-6 in frequency domain ranging from 30 MHz to 200 MHz.
