The Performance Screen
The performance screen gives a glimpse at how the clock is performing with regard to run time,
time quality and estimated holdover uncertainty. Run Time includes the number of power cycles,
previous run time (before the last power cycle), current run time and total run time. Time quality
is a 2
σ
estimate of accuracy. Estimated holdover uncertainty is an estimate of how the clock will
drift (based on the installed oscillator) over various time intervals if the clock were to lose lock
with the GNSS. Since these are dynamic values, you must read the clock to view new readings over
time. Those displayed are only good for the moment you last read the clock.
