Abstract :
A dual-resonator compensation method for reducing acceleration sensitivity of precision quartz oscillators have been developed. Readily available 10-MHz SC-cut resonators are counteraligned to cancel the individual Γ vectors. Phase noise under vibration is reduced to the level expected for the measured residual sensitivity. Performance characteristics of the newly developed FTS Model 1120 are described
