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.

Three Channel Low Phase Noise Rubidium GNSS GPS Disciplined 10MHz Frequency Reference-NR8403-ROG

Three Channel GNSS GPS Disciplined Rubidium 10 MHz Frequency Reference
Modular 10 MHz Rubidium Frequency Reference with Three Channels

NR8403-ROG

The NR8403 in a versatile modular package bring stability to almost any location. Wide power operating range with GNSS GPS locking to further enhance long-term stability. The low noise option adds an ultra-low phase noise OCXO that can be also vibration isolated to reduce mechanical induced phase noise. Phase noise < 155 dBc/Hz at 10kHz.  Popular in scientific, calibration labs and satellite up-links.
