Generally, a stable and accurate clock will show consistently stable offset (with variation in the order of a
few ppm). It means that it is not having to change its offset very much to stay in sync.
Show me
A histogram that shows a distributed range of offsets indicates an unstable clock - it is having to change its
offset significantly, and often, to stay in sync with the master clock. This can be due to overloaded network
links, or poorly-implemented EEE. A device in this state is highly likely to lose sync with the master clock.
Show me
A histogram that shows measurements in amber and/or red indicates a clock that might be currently
stable, but has little room for manoeuvre; its offset could easily move outside its pull range, at which point
it will lose sync completely. This can result when the master clock is derived from an inaccurate external
word clock.
Note: Dante Controller can be left running for a few days (or even weeks) to collect clock status
data, providing a long-term picture of the stability of your network clocking configuration.
