Abstract : It is the intention of this paper to demonstrate the temperature compensation limits of precision quartz crystal resonators mounted in the traditional HC-27/U glass enclosure. A computer-controlled hysteresis measurement station was set up to measure the thermal hysteresis (thermal retrace) of the resonator, which restricts attainable compensation accuracy. The station was used to take measurements of various crystals from 3 German manufacturers. When compared with the AT-cut specimens, the SC-cut crystals displayed no real advantages.
