Research on compensation method with additional phase for quartz crystal test network

IEC recommended π network zero phase method is the standard one for testing parameters of quartz crystal resonator. Main difficulty in realizing such method is the compensation for additional phase shift of π network. π network can be inspired by multiplexed output standard signal adjusted by phase difference. After testing the additional phase shift of π network, and then adjusting the phase difference of signal source, actively compensating the additional phase shift of network, the test precision can be significantly improved and requirements for π network manufacturing technology and operating environment will be lowered.
