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.
Low cost dual channel 10 MHz Rubidium frequency reference. Low noise OCXO is locked to the Rubidium source. Channels are continuously monitored and accessible via RS232
