在介绍π网络法石英晶体元件电气参数测量原理的基础上，设计了测量系统，并对π网络输出电压以及π网络两端电压之间相位差进行分析与建模，提出迭代法和对分法相结合的快速测量算法。此结合算法测量速度快、测试精度高，适合1-200MHz频段石英晶体元件半成品加工控制和成品测量，且通过实验证明整个测量系统的测量精度和稳定性都达到国际先进水平。
A quartz crystal units＇measurement system based on π network measuring method is introduced. A model is built on the output voltage of π network and the phase delay between its input voltage and output voltage after adequate research on them. A algorithm combining iterative algorithm and bisection algorithm is put forward. Because of its fast speed and high precision, it is used for semi-manufactured product＇s manufacturing control and finished product＇s measurement of quartz crystal units ranging from 1MHz to 200MHz.It was proved that measurement precision and stability of the whole measurement system has reached an international leading level.
