NR3700-OG | Dual-Channel Low Cost 10 MHz & 1 PPS Reference GPS/GNSS-Locked Auto Cal

10MHz Frequency Reference, OCXO, GPS/GNSS Locked Single Channel, Auto-Cal

NR3700-O/G

The NR3700-O/G is a GPS locked OCXO 10 MHz frequency reference with PPS and RS232. The unit features Auto-Calibration such that the most recent coefficients to compensate the OCXO for drift due to aging and/or temperature are stored and applied to the OCXO during GPS loss of lock conditions. These coefficients are updated after 8 hours of continuous GPS locked state. This effectively eliminates long-term OCXO changes.

Options: TCXO and Ultra Low Phase Noise OCXO

Product Features:

• GPS-locked 10 MHz OCXO frequency reference delivers ultra-stable, high-precision timing, ideal for telecom, broadcasting, and scientific applications

• Auto-Calibration technology stores and applies compensation coefficients for OCXO drift due to aging and temperature, maintaining accuracy even during GPS loss

• PPS and RS232 outputs provide flexible integration; PPS offers 30 ns rms accuracy, and RS232 port allows access to NMEA-0183 GPS data at adjustable baud rates

• Ultra-low phase noise and jitter achieved via advanced phase-locked loop design and optional ultra-low phase noise OCXO, ensuring clean, reliable frequency output

• Robust holdover performance: Calibration data is updated after 8 hours of GPS lock, eliminating long-term drift and ensuring stable operation during GPS outages

• Wide power input range from –60 V to +60 V DC (three selectable ranges) or optional AC adapter, supporting diverse deployment environments

• Short-circuit and transient-protected outputs: 10 MHz sinewave at 4.5 dBm and LVCMOS PPS, with built-in test and front-panel indicators for GPS lock and system health monitoring.
