Status / Information Windows
The SyncServer S600/S650 has separate timing and frequency clock controls. The
time and frequency clocks are usually in the same clock state. If they are different,
then the “Current Reference” row will include text after the icon which displays the
frequency clock state. The “Time of Day Status” always shows the time clock state.
While locking to a new reference, the two states may be different for a brief time.
If there are no valid timing references, but there is a valid frequency reference, then
there should be text shown since the frequency and time clock states are different.
The system time locks, but does not frequency lock to an NTP reference.
Therefore, the frequency status will display free-run while the system is locked to an
NTP reference and there are no frequency references connected.
Frequency
References
This row shows all enabled
frequency-only references.
The use of a frequency reference is
thought of as a method for
holding-over time when there either
was never an active time source or it
was lost.
If a holdover source is ready
to be used it will be
green.
If it is not ready it will be
red.
Leap Pending This row indicates if a Leap second is
pending.
If there is no warning of a
Leap second pending it will
be
green.
If there is a warning of a Leap
second pending it will be
red.
