Specifications

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.
