  • Page 4: Summary

    Users manual NR2110-OG Revision #: Date: 3/17/17 1.0 Summary The NR2110 is a Single Channel precision GNSS/GPS locked 10MHz frequency reference. The amplifier is a low phase noise design to preserve the integrity of the reference signal. All outputs are transient and fault protected.
  • Page 5 Users manual NR2110-OG Revision #: Date: 3/17/17 The NR2110-OG delivers a low phase noise curve, which can be seen in the sample production test below. NR2110-OG Phase Noise Measurement Page #: 5 of 46 www.novuspower.com...
  • Page 6 Users manual NR2110-OG Revision #: Date: 3/17/17 The unit features extensive reporting via the rear panel RS232 port. Equipment status, output voltage on each channel and redundancy status. By being able to monitor the output voltage, the user can detect cabling issues that cause an impedance change and replace cabling before it completely fails.
  • Page 7 Users manual NR2110-OG Revision #: Date: 3/17/17 Nominal power is global AC power but a DC power option can be ordered that acts as the back-up power supply. Nominally 24 vdc, this port is used for power when AC power fails. Switching between power sources is automatic and there is no transient power outage at the equipment level.

  • Page 8: Controls And Indicators – Front Panel

    Users manual NR2110-OG Revision #: Date: 3/17/17 2.0 Controls and Indicators – Front Panel This section describes the functionality of the front panel controls and indicators. Two buttons above the status LEDs provide navigation through the menus. In general, the NEXT button advances through the menus to the next screen, while the SELECT button chooses between the available values on a menu.

  • Page 9: Gnss Status

    Date: 3/17/17 2.1 GNSS Status On power up, the NR2110-OG will display the Time and Date as well as the current status of the GNSS receiver. If the unit is dual time based, both receivers will have status displayed. GNSS: The GNSS status indication allows the user to observe the Lock status of the receivers, and the number of GNSS satellites in view.

  • Page 10: Channel Status

    Users manual NR2110-OG Revision #: Date: 3/17/17 2.3 Channel Status The Channel Status can be determined by reading the actual RMS value on the output of each stage. This is compared to a threshold limit that is set by the user as a percentage variation from a saved value.

  • Page 11: Status Leds

    Users manual NR2110-OG Revision #: Date: 3/17/17 2.4 Status LEDs There are three status LEDs which provide a quick indication of valid unit operation. Alert LED: The Alert LED will illuminate flashing red to indicate A GNSS failure or a power supply failure. The Alert LED will not flash RED if any valid input signal is present.

  • Page 12: Power Supply Status

    Users manual NR2110-OG Revision #: Date: 3/17/17 2.5 Power Supply Status The Power Supply Status screen provides DC voltage values of the two available power supply sources. The 90-250V AC input is internally connected to an internal 24V AC-DC convertor which powers the internal supplies with 24V.
  • Page 13 Users manual NR2110-OG Revision #: Date: 3/17/17 If the optional external DC Power supply is requested, redundant power supplies will operate on either the AC input or DC input, and function independently. All functionality and reporting for an individual power supply and amplifier is independent of its redundant copy.

  • Page 14: Alert Threshold

    Users manual NR2110-OG Revision #: Date: 3/17/17 2.6 Alert Threshold The Alert Threshold screen allows the user to adjust the tolerance from the Reference Voltage which, if exceeded in either direction, the output channel will report a fault status. The default threshold value is set at ±25% percent from the current state of the amplifier, and is user programmable in 5% increments, from ±10% to ±60%.
  • Page 15 Users manual NR2110-OG Revision #: Date: 3/17/17 The Alert Threshold can be optimized so that a channel short or an impedance change will cause an Alert. Page #: 15 of 46 www.novuspower.com...
  • Page 16 Users manual NR2110-OG Revision #: Date: 3/17/17 Example: The output of channel 1 is connected to a high impedance input and reports 1.25Vrms at the output. Alert threshold is set to +/-20%. The current state is saved in the Save Configuration screen.

  • Page 17: Latch Channel Value

    Users manual NR2110-OG Revision #: Date: 3/17/17 2.7 Latch Channel Value The Latch Channel Values Screen allows the user to save the current channel output value for use as the Reference Value for Alert settings. A channel Alert is triggered when the channel output voltage exceeds or falls below a percentage of the Reference Value.

  • Page 18: Fault Status

    Users manual NR2110-OG Revision #: Date: 3/17/17 2.9 Fault Status The Fault Status screen allows a quick overview of any Channel faults from the front panel. Press SELECT to advance to the System Fault Screen. The System Fault Screen indicates any failures in the primary system or the redundant backup system.

  • Page 25: Phase Noise

    Users manual NR2110-OG Revision #: Date: 3/17/17 4.1 Phase Noise Low phase noise contribution is achieved through careful PCB design, component selection and minimization of power supply noise. Below is a typical phase noise performance for a 10 MHz reference application:...

  • Page 26: Outputs

    Users manual NR2110-OG Revision #: Date: 3/17/17 4.2 Outputs Each output is fault and electrostatic discharge protected. Each output is independent and any output can be faulted for an indefinite period of time with no permanent damage. Each output is connected to a monitor circuit that detects a local fault on the output.

  • Page 27: Built In Test

    Users manual NR2110-OG Revision #: Date: 3/17/17 The base unit is configured for nine 10 MHz sine wave outputs and one PPS output. The outputs can be configured as 10 sine outputs. Low Impedance 100mA Drive 4.3 Built in Test There are number of power supplies in the design to meet special needs and noise reduction.

  • Page 28: Crystal

    Date: 3/17/17 5.0 Crystal Novus crystal based frequency reference products are based upon either TCXO or OCXO technology. Temperature compensated crystal oscillators will normally use a 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 fix temperature to minimize temperature drift.
  • Page 29 Users manual NR2110-OG Revision #: Date: 3/17/17 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 30 Users manual NR2110-OG Revision #: Date: 3/17/17 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 31 Users manual NR2110-OG Revision #: Date: 3/17/17 Typical Phase Noise Performance-Rubidium with OCXO When the stability of an atomic or crystal source is not sufficient a GNSS disciplined source is an option. A GNSS receiver is installed and timing information from the GNSS is used to discipline the timing device.
