Contact Support iReference+ Smart GNSSource-1000 Manual


The GNSSource-1000 is a low-cost, high performance GPS/GNSS primary reference source. It integrates a smart, low-noise disciplining OCXO and a GPS/GNSS receiver.

It integrates a GPS/GNSS disciplinable GXClock-500 function, using SmarTiming+R technology with an auto-adaptive loop time constant from 100 to 10,000 seconds, depending on the GPS/GNSS signal quality, at cutting-edge 1ns resolution.

The Spectratime GNSSource-1000 is specifically designed for cross-industry applications, where high stability and timekeeping features are required.

Applications:

  • Synchronization
  • Timing
  • Reference/Test Source
  • Time/ Frequency Source

ADVANTAGES

  • SmarTiming+® Technology

    Using SmarTiming+® technology integrated inside the chassis, GNSSource™-1000 is able to provide you with ultra high 1ns resolution.

  • Calibration For Scientific Precision

    With its integrated smart auto calibration, the GNSSource™-1000 saves costly set up time as well as minimizes errors in timing information.
