Rubidium Sources

Rubidium frequency references are more stable than mechanical systems, with holdover stability 50 times better than OCXOs. Basic products include NR2110-R and NR2310-R, but atomic reference phase noise may not be acceptable. To solve this, a low noise OCXO is incorporated and disciplined to Rubidium, creating a low noise, high stability reference (NR2110-R/O, NR2310-R/O).

For even better long-term stability, GNSS disciplined 10 MHz references are available (NR2110-R/O/G, NR2310-R/O/G, NR8403-RO).
