摘　　要：文章针对当前石英晶振谐振频率测试系统存在诸如:测试频率范围低、次生谐振频率无法逾越的问题,根据不同的测试要求和应用场合,分别设计了π网络最大传输法和零相位测试法两种测试方法。详细阐述了两种测试方法的设计方案与具体实现,并分别给出了谐振频率标称值为10MHz和95MHz下两种测试方法得出的具体实验数据。The article introduces the design scheme of a quartz oscillator frequency measurement system, which is based on the method of π network. It successfully solves the problems of traditional quartz oscillator frequency measurement system, just like the measure range is too scanty, the precision is too low, and so on. The article describes the two measurement methods： most transfers technique and zero phase technique in a π network detailedly. The two groups of experiment data have been given out （the standard frequency is 10MHz and 95MHz）.
