Abstract

We present data which shows correlations between phase fluctuations in a low g-sensitive 10 MHz oven-controlled quartz oscillator (OCXO) and acceleration/vibration sensors. We describe the equipment setup and measurement procedure. Data is in the form of scatter plots, which we find to be highly informative compared to usual L(f) plots when the oscillator is subjected to vibration.
