  • Page 4 REVISION DATE 7/17/20 The NR2310-O/G is a GNSS-locked OCXO 10 MHz frequency reference with PPS and RS232. 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. These coefficients are updated after eight hours of continuous GPS locked state.
  • Page 5 The phase noise of the output is now largely dominated by the voltage-controlled oscillator. The oscillator is typically a crystal oscillator and the quality of that device can vary significantly. The NR2310-O/G uses an oven-controlled oscillator to provide an unlocked stability of under ±50 ppb/year.
  • Page 6 DATE 7/17/20 Crystal - The Time Base Novus crystal-based frequency reference products are based upon either TCXO or OCXO technology. Temperature compensated crystal oscillators will normally use an AT cut crystal and electronically compensate the device with temperature. An OCXO device uses a SC (stress compensated) crystal and the part is held at a fixed temperature to minimize temperature drift.
  • Page 7 USERS MANUAL NR2310-O/G REVISION DATE 7/17/20 Over a broad temperature range, an AT performs very well and much easier to compensate electronically. It is also a simpler crystal to manufacture than a SC cut device. For applications where a stability of a few ppm is acceptable, a TCXO can be a cost-effective alternative.
  • Page 8 USERS MANUAL NR2310-O/G REVISION DATE 7/17/20 Typical OCXO Another alternative for a frequency reference is an atomic reference. These devices use a change in atomic state of an isotope of Cesium or Rubidium for stability. Instead of a stability of ±50 ppb/year for a typical OCXO- stability of ±1 ppb/year is very common.
  • Page 9 USERS MANUAL NR2310-O/G REVISION DATE 7/17/20 TYPICAL PHASE NOISE PERFORMANCE – RUBIDIUM WITH OCXO When the stability of an atomic or crystal source is not sufficient, a GNSS disciplined reference is an option. A GNSS receiver is installed and timing information from the GNSS is used to discipline the timing device.
  • Page 10 USERS MANUAL NR2310-O/G REVISION DATE 7/17/20 GNSS Receiver The receiver and companion elements generate the GNSS sine wave, PPS and NMEA serial link. The serial link conforms to NMEA 0183 protocol. The 26 channel, high-sensitivity, high-accuracy multi-GNSS receiver supports TRAIM, GPS, GLONASS, QZSS, SBAS, Active Anti-Jamming and Advanced Multipath Mitigation Functions.

If a supply fails to meet test limits, an alert is generated. Channel Faults: If a channel fault is detected, an indication is given for the individual channel, but an alert is not generated.
  • Page 16 USERS MANUAL NR2310-O/G REVISION DATE 7/17/20 The demands on the power supplies are two-fold - maximum efficiency and minimum noise. Maximum efficiency reduces power dissipation in the unit. Temperature impacts reliability and stability. To achieve maximum efficiency, the primary converter is a switching converter with an efficiency of approximately 90%.
