石英晶体元件参数的测量 第9部分：石英晶体元件寄生谐振的测量
Application Summary AI generated
This standard specifies methods for measuring spurious (unwanted) resonances in piezoelectric quartz crystal units. It is applied in the electronics industry for quality control and performance testing of crystal oscillators and filters used in communication devices, timing circuits, and frequency control systems. The standard ensures that parasitic resonances are identified and quantified to prevent signal interference and maintain device stability.
