Atomic References

Rubidium references, unlike a mechanical resonant system, offer a stability that is over fifty times that of an OCXO. Our standard stability is less than 1 ppb/year with options that allow even better performance. We have two basic platforms for our atomic products - the NR2110 single channel and the NR2310 ten channel 10 MHz reference. These platforms incorporate low noise amplifiers that are fault and transient protected, low noise power supplies and built-in test.

Our basic Rubidium references offer excellent stability at a moderate price. Atomic reference phase noise levels may not be acceptable for many applications. To provide a stable low noise source, a low noise OCXO is incorporated that is disciplined to the Rubidium reference.

Ultra Low Noise Atomic Source

Ultra Low Noise

The phase noise for a standard Rubidium source is not acceptable for some applications. Our low noise Rubidium frequency reference incorporates a low noise OCXO that is locked to the Rubidium source. This combination gives you the best of two technologies - the stability of Rubidium and the low noise of an OCXO

Multi Channel Atomic Source

Multi Channel

Ten channel Rubidium frequency reference with a stability of <2 ppb/year. A cost effective source that frequently eliminates the need for a distribution amplifier. Single RU design without the need for a fan.  Unit features monitoring on all ten channels that are fault and transient protected. Built-in test drives a relay contact that can be connected to an alarm panel.

Single Channel Atomic Source

Single Channel

Basic rackmount Rubidium reference -

0.5 E-10 /month aging.  A cost effective timing solution when GPS is not available.

GPS GNESS Locked Reference

GPS/GNSS Locked

To achieve even greater long-term stability, the Rubidium reference is locked to the GPS/GNSS.  This combination gives you the best of three technologies - the stability of Rubidium, the low noise of an OCXO and the long-term stability of GPS/GNSS.
