    USERS GUIDE NR2310D-ROG REVISION DATE 031121 Safety This product has been designed and manufactured to recognized safety standards and rules. The product is a sophisticated electronic instrument that should be installed and operated by highly trained professionals. Installation of this equipment should comply with all local electrical codes.
  • Page 5: Mounting

    For applications where there is significant shock and vibration, Novus offers equipment with interior mechanical design features to minimize the effects of vibration and shock on the equipment performance.
  • Page 6: Summary

    DATE 031121 Summary The NR2310D-ROG is a high performance 10 channel, 10 MHz, GNSS Locked Rubidium frequency reference. The core time base is a Rubidium source that is disciplined with the timing information from the GNSS. The Rubidium source is followed by a low noise OCXO locked to the Rubidium.
  • Page 7: The Gnss-Locked Reference

    OCXO, a Rubidium or some other device - is controlled. Environmental factors such as temperature, shock and vibration all impact the overall system. Over the years, Novus has invested heavily in the design of locked references and can offer four levels of GNSS locking performance. Each level of performance is discussed to allow the system designer to determine the level of performance required versus system cost constraints.
  • Page 8: The Time Base

    031121 The Time Base The heart of the system is the reference. Novus offers OCXO and Rubidium based references. Because of the relatively poor phase noise performance of Rubidium, many of our customers select a Rubidium with a cleanup OCXO to achieve high stability and low phase noise.
  • Page 9: The Gnss Receiver

    There are likely hundreds of GNSS receivers available with a range of functionality. Novus uses a few that are selected to meet the needs of our reference and PPS (pulse per second) sources. PPS stability and accuracy varies with each radio and cost rises with performance.
  • Page 10 USERS GUIDE NR2310D-ROG REVISION DATE 031121 Depending upon the locking algorithm, the radio PPS variation can contribute directly to phase noise and uncertainty. Novus uses two types GNSS receivers depending upon the stability options installed in the unit. Page #: www.novuspower.com...

  • Page 16 USERS GUIDE NR2310D-ROG REVISION DATE 031121 Advanced GNSS-Locked Reference (HS2) Our most advanced designs address long time constants digitally. High performance picosecond measurement techniques provide greater timing resolution. Advanced algorithms coupled with precise analog designs that are thermally controlled, and vibration isolated allow Allan Deviation performance approaching E-14.
  • Page 17 USERS GUIDE NR2310D-ROG REVISION DATE 031121 Our algorithms process the radio information to achieve a more stable reference. The curve below is a plot of timing jitter after processing: The standard deviation improved from 17 ns to approximately 400 picoseconds. The most advanced loop reports calculated Allan Deviation on real time basis locally on a display and/or a selected comm port.
  • Page 18 Thermally Isolated Reference (HS3) Thermally and Vibration Isolated Reference (HS4) To further enhance performance Novus offers thermal and vibration isolation. The thermally isolated unit adds a thermal plate held at a fixed temperature and an additional case around the reference to provide insulation. The vibration option adds vibration isolators to attenuate shock and vibration coming from the environment.
