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 three basic platforms for our atomic products - the NR2110 single channel and the NR2310 ten channel and the NR2316 sixteen channel 10 MHz reference. These platforms incorporate low noise amplifiers that are fault and transient protected, low noise power supplies and built-in test. The NR2316 platform offers local and remote control via SNMP.

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.

For remote applications, our P-option adds an ethernet port, local display, controls and SNMP.

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.
