GNSS GPS Disciplined Oscillator 50 MHz Reference-NR7400-50


GNSS Locked OCXO Based 50/100 MHz Frequency Reference

GNSS Disciplined 50/100MHz  Frequency Reference also Offers External Locking to PPS or 10 MHz


GNSS GPS Disciplined OCXO based, 50 or 100 MHz frequency reference. The unit features auto-calibration so 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. High performance 26 channel GNSS receiver that supports GPS, GLONASS, SBAS, QZSS. By being able to receive data from multiple satellite constellations, lower lock time is achieved. Unit is also capable of locking to an external 10 MHz reference. Low phase design results in a reference ideally suited to high frequency applications -i.e. satellite up links- where the higher operating frequency affords a 14 dB reduction in phase noise versus a 10 MHz reference. The unit may also be locked to an external 10 MHz reference or PPS source. It may also be stabilized to an internal Rubidium reference.

  • OCXO holdover.
