Spirent TestCenter: How much accuracy can we expect for IEEE1588v2 clients when STC is master clock, which is in Sync with GPS receiver?

Environment/Versions
  • Spirent TestCenter
  • IEEE1588v2
  • GPS
Answer

  • GPS clock synchronizes the chassis internal clock.
  • When STC emulates a 1588 Master clock it gets its clock from the Chassis clock.
    • Note: It gets only the seconds value of the chassis clock and uses that as a basis to add in the hardware timestamp on the card.
    • Thus if the chassis gets it’s time of day time from GPS, then in some regards we are using it as a basis for our 1588v2 emulated time of day.
