Portable 10 MHz OCXO or Rubidium based GNSS Disciplined Frequency Reference Holdover Stability < 0.5 ppb

NR300

The frequency reference that allows you to start out in a GNSS environment then bring the reference into a GNSSS denied environment and hold < 0.5 ppb for 4 hours. Once you return to a GNSS available environment the instrument will report the amount of drift that occurred in the denied environment. GNSS-locked 10 MHz OCXO based frequency reference locked to a 26 channel multi-satellite system receiver,  Unit produces 3- 10 MHz Sine, 1PPS, NMEA and a synthesized secondary channel that can range from 14 kHz to 10 MHz.   Auto-calibration maintains output stability in an intermittent GPS environment. Battery provides for in excess of four hours of use.  Event inputs record to 100 ns resolution. Rubidium PPS holdover < 5 usec/day
