TL;DR
This paper investigates correlations between external measurement parameters and noise in quartz crystal resonators using an advanced phase noise measurement system.
Contribution
It introduces a systematic approach to analyze how drive level, temperature, and tuning capacitor affect resonator noise.
Findings
Resonator noise varies with drive level, temperature, and tuning capacitor.
Measurement system effectively captures noise correlations.
Results aid in understanding and reducing resonator noise.
Abstract
The first step, before investigating physical origins of noise in resonators, is to investigate correlations between external measurement parameters and the resonator noise. Tests and measurements are mainly performed on an advanced phase noise measurement system, recently set up. The resonator noise is examined as a function of the sensitivity to the drive level, the temperature operating point and the tuning capacitor.
