Abstract :
Recent interest in a quartz-crystal cut, which is compensated for stress effects and thermal gradient effects on its frequency characteristics, has required further experimental confirmation of its suitability for high-precision frequency standards. Presented in this note are experimental data on the performance of 51 units fabricated in the vicinity of (yxwl) 21.93°/33.93° along with mode spectra plots and temperature-performance data for a typical quartz resonator.
