A crystal oven is a temperature-controlled chamber used to maintain the quartz crystal in electronic crystal oscillators at a constant temperature, in order to prevent changes in the frequency due to variations in ambient temperature. An oscillator of this type is known as an Oven-Controlled Crystal Oscillator (OCXO, where "XO" is an old acronym for "crystal oscillator".) This type of oscillator achieves the highest frequency stability possible with a crystal. They are typically used to control the frequency of radio transmitters, cellular base stations, military communications equipment, and for precision frequency measurement.

Famous quotes containing the words crystal and/or oven:
“We have ... a thirst unquenchable, to allay which he has not shown us the crystal springs. This thirst belongs to the immortality of Man.... It is no mere appreciation of the Beauty before us—but a wild effort to reach the Beauty above.”
—Edgar Allan Poe (1809–1849)
“Occasionally, remind children tactfully that the oven is the only self-cleaning appliance.”
—Fred G. Gosman (20th century)
