GPS500 GPS Zeitcode Generator

Der GPS500 ist ein präziser IRIG-B oder SMPTE Zeitcode Generator. Als sehr genaue Zeitquelle bezieht er seine Zeitinformationen aus den Atomuhren des GPS Satellitensystems. Das Gerät extrahiert die Zeitinformationen aus dem Satelllitensignal und generiert einen Zeitcode, der mit einer Genauigkeit von besser als 10 Microsekunden auf UTC (Universal Coordinated Time).


  • Generates SMPTE, EBU or IRIG-B Time Codes
  • Synchronized to atomic clocks in GPS satellites
  • -11.5 to +12 hour time zone offsets in 30-minute increments
  • Automatic Daylight Saving Time 
  • NMEA/Kinemetrics/Truetime serial protocol output
  • Wide DC power supply input range: 12 to 48 VDC
  • Switch selectable Time Zone and DST
  • Switch selectable format and baud rate



Time Reference

  • When synchronized, the Time Code accuracy is:
    • SMPTE output accuracy of ± 20 microseconds
    • IRIG-B0 (DCLS/PWM) output accuracy of ± 90 microseconds
    • IRIG-B1 (AM) output accuracy of ± 1.4 milliseconds
    • PPS output accuracy of ± 60 nanoseconds
  • Should the GPS500 lose GPS signal it will revert to an internal TCXO oscillator and maintain an accuracy of ± 1 minute per year. The PPS output is synchronized to the internal TCXO oscillator.
