  • Page 3 Users manual NR7000 Revision #: Date: 102121 1.0 Summary The NR7000 is a GNSS-locked OCXO 10 MHz frequency reference with auto-calibration. It features a 10 MHz Sine output that is fault and transient protected. The unit is also available at 50 and 100 MHz The unit also provides a PPS and NMEA 0183 at full RS232 levels.

  • Page 5 Users manual NR7000 Revision #: Date: 102121 OCXO Warm-up Characteristics Power required is 5.0Vdc to 5.5Vdc. This must be a low noise source. Local filtering is recommended. There is internal filtering but noise on the input power, while attenuated, can compromise phase noise.
  • Page 6 Users manual NR7000 Revision #: Date: 102121 The NR7000 continually monitors temperature and aging so that, when the unit goes into holdover or loses GNSS lock, the output frequency reverts to the last known locked frequency value. The calibration feature continually monitors the correction coefficients developed through GNSS timing information.

  • Page 12 Users manual NR7000 Revision #: Date: 102121 5.0 Power The platform is designed to operate from +5Vdc to 5.5Vdc. The unit is also fused with a 5 Amp slow blow. Caution should be exercised when connecting power to the NR7000. The unit is reverse voltage protected with a TVS diode.
  • Page 13 Users manual NR7000 Revision #: Date: 102121 6.0 GNSS Function The receiver needs to be able to see at least four satellite vehicles (SVs) to obtain an accurate 3-D position fix. When travelling in a valley or built-up area, or under heavy tree cover, you will experience difficulty acquiring and maintaining a coherent satellite lock.
  • Page 14 Users manual NR7000 Revision #: Date: 102121 The receiver will now know that it lies somewhere on the circle of points produced where these two spheres intersect. When a third satellite is detected and a range determined, a third sphere intersects the area formed by the other two. This intersection occurs at just two points.
