Three Channel , 10 MHz Self-Calibrating Frequency Reference

The NR3623 CAL 10MHz frequency reference which features Auto-Cal, continously monitors the correction coefficients being applied to the OCXO to compensate for aging and temperature stability. The coefficients are stored in non-volatile memory and in the event of GPS loss are used to maintain the accuracy of the crystal.  Frequency loss offset +-10 ppb..  A good choice for general lab use, Simulcast and test systems.

  • Triple output can eliminate the need for a distribution amplifier

  • Channel monitors alert to a severe impedance mis-match

  • All outputs fault and transient protected

  • Holdover stability of 5 ppb/day - 50ppb/year

  • Locked accuracy <4E-11

  • operates from +60 to -60 VDC in three ranges

  • PPS Accuracy 20 ns rms

  • Channels can be allocated to PPS or 10 MHz

  • Indicators provide GPS lock and unit self test status.

  • Available in a kit form which includes reference, antenna, 50' cable and power adapter

  • High performance 26 channel GPS receiver that supports GPS, GLONASS, SBAS, QZSS
