Rubidium Frequency Standards

Rubidium Frequency Standards

Rubidium frequency standards are a low-drift alternative to an OCXO or TCXO with stability of < 1 ppb/year. As high-precision oscillators, Rubidium frequency standards are especially useful for measurement, testing, and many telecommunication applications. To further enhance a Rubidium based frequency reference, Novus offers Rubidium frequency references with an embedded low phase noise OCXO to meet system frequency reference phase noise requirements. A Rubidium reference is alternative source if a GPS disciplined oscillator is not an option.

Affording excellent stability, Rubidium frequency standards are a next best choice when operating in a GPS denied environment. That being said, adding a GPS-locking system will improve the 1ppb/year drift by approximately three orders of magnitude. For typical telecommunication infrastructure, GPS, or other types of applications, Rubidium standards offer excellent holdover performance.

16 Channel,Low Noise Rubidium, GNSS-Locked 10 MHz Frequency Reference - NR2316D-ROG

16 Channel GPS GNSS Disciplined Rubidium 10 MHz Frequency Reference


High Stability 16 Channel GNSS Locked 10 MHz Frequency Reference

A solid, 16 channel platform. Rubidium source provides outstanding stability. Embedded 26 channel GNSS receiver locks and stays locked in weak signal environments. Transient and fault protected channels designed for the a high level electromagnetic environment to provide years of reliable service.  AC and DC power options available for critical installation.


•16 channel 10 MHz reference with built-in GNSS receiver. 

•16 channel GNSS GPS locked OCXO 10 MHz frequency reference.

•Low phase noise OCXO –  140dBc/Hz at 100 Hz.

•Rubidium source stability < +-5E-11/month

•Locked accuracy <3E-11.

•16 channels very often eliminate the need for a distribution amplifier.

•Harmonics are well below -30dB.

•Chassis is 1 RU (~1.7 inches) and saves valuable rack space.

•All inputs and outputs are transient protected.

•Built-in test.

•Unit features auto-calibration to compensate for long-term drift.

•High performance 26 channel GPS receiver that supports GPS, GLONASS, SBAS, QZSS. By being able to receive data from multiple satellite constellations, lower lock time is achieved. Maintaining lock in poor signal environments is enhanced.

1PPS available

Optional Networking and SNMP available (for a 10 channel platform see NR2310D-O/G )
