Acceleration Sensitivity Characteristics of Quartz Crystal Oscillators

The resonant frequency of every quartz crystal is affected by acceleration forces. The nature of the effect depends on the type of force that is being applied. Changes in the static gravitational force being experienced such as tilting or rotation will cause a step offset in frequency. Time dependent acceleration or vibration will frequency modulate the output. A shock pulse will cause a sharp temporary perturbation in the output frequency.
