Rubidium 10 MHz Frequency 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 2 ppb/year with options that allow even better performance. We have two basic platforms for our atomic products - the NR2110 single channel and the NR2310 ten channel 10 MHz reference.. These platforms incorporate low noise amplifiers that are fault and transient protected, low noise power supplies and built-in test.
Our basic products are the NR2110-R and NR2310-R Rubidium frequency references which 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. This results in a low noise, high stability reference (NR2110-R/O, NR2310-R/O). For applications demanding even better long-term stability, we offer GNSS disciplined 10 MHz references that offer the long-term stability of GNSS disciplining, low noise of a high performance OCXO and short-term stability of Rubidium (NR2110-R/O/G, NR2310-R/O/G).
