6 Channel 10 MHz Reference in PC104 Form Factor-NR4600-O/G

PC104 Six Channel 10 MHz GNSS Locked Frequency Reference with PPS and NMEA


Six independent 13 dBm sine outputs that are fault and transient protected and individually monitored. Channel status available over RS232 port. NMEA -0183 port at full RS232 levels or 3.3 Vdc logic. PPS at 3.3 Vdc  Only a single voltage power source required. The unit also features auto-calibration that compensates for long-term crystal drift to provide years of precise performance. There is also a GPS lock status signal, PPS and serial port to provide access to NMEA  and equipment status.

  • 26 channel high-sensitivity, high-accuracy multi-GNSS receiver. Supports TRAIM, GPS, GLONASS, QZSS, SBAS, Active Anti-Jamming and Advanced Multi-path Mitigation functions.
  • PC104 compliant mechanical design.
  • Operates from -60 to +60 Vdc power in three ranges.
  • Auto-calibration minimizes long-term drift.

    Kits are available that include antenna, cables and power supply. Several features can be customized at the factory – frequencies other than 10 MHz either from a unique crystal or with a built-in synthesizer that is GNSS-locked. Time stamping capability to 100ns resolution. To meet unique requirements, we have shipped product with output features requiring a custom amplitude, square wave output, high voltage and high current drive.
