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.
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.
