The NR3620-HS-R provides a precise 10 MHz GNSS-disciplined frequency reference with Rubidium holdover stability. Its low phase-noise OCXO, Allan Deviation monitoring, IRIG-B timecode output, and full RS232/NMEA reporting make it ideal for laboratories, timing distribution, synchronization, and RF test environments. Designed for reliability, it ensures accuracy even during GNSS outages using auto calibration and Rubidium stability.

FAQ

1. What makes this oscillator high-stability?
   The combination of Rubidium holdover, low phase-noise OCXO, and continuous Allan Deviation monitoring ensures exceptional stability.
2. Does it support both AC and DC power?
   Yes. Standard input is 12 VDC, with an optional AC adapter and extended DC ranges available for flexible integration.
3. Can it output IRIG-B timecode?
   Yes, IRIG-B formats 000, 120, and 124 are supported in addition to the 10 MHz and PPS signals.
4. How is system status monitored?
   Via RS232 reporting, NMEA output, Allan Deviation logs, and visual lock indication from the front panel and relay contacts.
