An OCXO is an extremely reliable frequency timing device. It is a standard crystal oscillator whose internal temperature is controlled and maintained consistently by a small internal thermostatically regulated mini-oven.
The high level of frequency stability provided by oven-controlled oscillators is essential for many electronic communication systems, field testing devices, and other similar laboratory equipment.
Applications requiring thermal stability of at least ±1 x 10-8 frequently use OCXOs. Nonetheless, if more precise frequency stability is needed, ranging from ±1 x 10-10 to ±5 x 10-1, a double oven-controlled crystal oscillator can be employed.
No matter how many different temperature control methods are used, quartz crystals are still susceptible to thermal expansion which is the prime cause of frequency drifts.
Therefore, cutting edge OCXO is configured and fabricated by Raditek using the two most popular cut types: AT cut for +80°C turning point and AT cut for 80°C turning point to rein-in the oscillator from drifting.
Our OCXO which are available in various packages and styles offers substantially superior frequency pulse stability and consistent performance than a conventional oscillator.
Additionally, Raditek engineers recommend doing routine maintenance on the heating element and quartz crystal and recalibrating the device as necessary to ensure that it always runs at maximum efficiency.
