【Abstract】 To increase the measuring accuracy of the resonant frequency of quartz crystal , The principle of the method of π-network and the effect of the stray reactance to the measuring result have been researched and analyzed. On the basis of research a measuring experiment system is designed.The measuring accuracy of series resonant frequency of quartz crystal resonator is ±2ppm ranging from 1 MHz to 120 MHz. The measuring method is in accord with international standard. The performance of the system is better than that of impedance meter type instruments, which are widely used in China.更多还原
