Frequency retrace of quartz oscillators
Abstract
Frequency retrace measurements are reported on oven controlled quartz oscillators utilizing AT and SC cut plated and BVA resonators. Prior to full aging, the retrace error is added to the aging effect. With well-aged resonators, after one or several on-off cycles, the frequency settles at a new level characteristic for intermittent operation. Severe frequency shifts have sometimes been found after the first restart following prolonged continuous operation. SC cut resonators appear to show distinctly smaller retrace errors than AT cut.
