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 optional 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: RS232,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
-
Optional 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.
