Abstract : A high stability quartz crystal oscillator is made from a quartz crystal plate by first cutting the quartz crystal plate at the angles that results in a resonator having a turnover temperature below the lowest operating temperature of the equipment in which the oscillator is to be used. A resonator is made from the quartz plate; the resonator then connected into a high stability oscillator circuit, and the oscillator-circuit/resonator combination placed into a temperature controlled environment where the temperature is maintained at a temperature between the lowest operating temperature of the equipment in which the oscillator is to be used to about -250 C.
