摘要
微调机是石英晶体谐振器成品生产的主要设备,其频率测量系统的精度决定了微调机的微调精度。论述了将阻抗计测频方法用于晶体频率微调时晶体的理想模型和实际测量模型的差异,从理论上分析了这些差异对测量结果的影响,提出了相应的误差修正方案,结果表明测量系统具有很高的测量精度。所采用的误差修正方法对晶体电参数的测量具有普遍的意义。
The final-plating machine is one of the main equipment for producing the quartz crystal resonators,The accuracy of its frequency measurement system is to define the accuracy of the integral machine.The difference between the theoretical model of quartz crystal and the realistic equivalent was suggested.The effect of these differences on the results of measure- ment was analyzed theoretically,and the appropriate error-correcting plan was put forward, and results in the high accuracy of the measurement system.
