PPS Disciplined 10 MHz Reference NR6720-PPS

10 MHz Low Noise OCXO, PPS Locked Frequency Reference

NR6720-PPS

The NR6720-PPS locks a low noise OCXO to an external PPS signal,  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/GNSS loss of lock conditions. The unit operates from a nominal 12 Vdc power source or available AC power adapter. Unit can be configured to operate from -60 to +60 Vdc in three ranges.

  • Holdover stability of 5 ppb/day,  50ppb/year.
  • PPS stability option- P-P jitter < 700 ps.
  • Locked accuracy <4E-11.
  • Available -60 to +60 Vdc in 3 ranges.
  • Indicators and signals provide GPS/GNSS lock and unit self-test status.

Kits are available that include antenna, cables and power supply. Several features can be customized at the factory – frequencies other than 10 MHz either from a unique crystal or with a built-in synthesizer that is GNSS-locked. Time stamping capability to 100ns resolution. To meet unique requirements, we have shipped product with output features requiring a custom amplitude, square wave output, high voltage and high current drive.
