Technique for Measuring the Acceleration Sensitivity of Quartz Resonators

Abstract

We present a simple method for measuring the acceleration sensitivity of quartz resonators. This method utilizes readily available electronic components and the voltage-frequency effect in doubly-rotated cuts, or a simple VCO for singly-rotated cuts, to determine botrh phase and magnitude information. The method is based on monitoring vibration-induced FM sidebands of an oscillator with a spectrum analyzer while applying acceleration compensation. An op amp circuit with reversible polarity is used to supply a compensation signal which is proportional to an accelerometer output. Since the goal is to observe a reduction or increase in FM sideband magnitude, the phase and magnitude requirements of the compensation circuit are less than that required for high level compensation.
