Evaluation of the Performance Characteristics of BVA Resonators under Static and Dynamic Conditions

摘要

This report presents results on evaluation and development of precision oscillators utilizing a novel quartz frequency control element, the BVA resonator. Performance characteristics of the BVA were evaluated utilizing an ensemble of oscillators all having SC-cut BVA resonators. Important results include the demonstration of low g-sensitivity, reduced sensitivity to thermal stress, and very good frequency stability. The systematic dependence of aging rate on crystal drive level was investigated. A high precision BVA oscillator was delivered to the procuring agency. Throughout the program, technical coordination efforts have involved AFSC, DRET (France) and OSA (SW). (Author)
