Reference Status panel
REFERENCE: Indicates the name type of each reference. These are determ-
ined by the inputs set up for the SecureSync
PRIORITY: Indicates the priority of each reference. This number will be
between 1 and 15. References in this panel appear in their order of priority.
See "Configuring Input Reference Priorities" on page205 for more inform-
ation.
STATUS: Indicates which available input reference is acting as the Time ref-
erence and which available input reference is acting as the 1PPS reference.
Green indicates that the reference is present and has been declared
valid.
Orange indicates the input reference is not currently present or is not
currently valid.
Performance panel
Disciplining State—Indicates whether or not the internal oscillator is cur-
rently being disciplined (steered to an input reference).
1PPS Phase Error—An internal measurement (in nanoseconds) of the
internal 1PPSs’ phase error with respect to the selected input reference (if
the input reference has excessive jitter, phase error will be higher)
10MHz Frequency Error—An internal estimated calculation (in Hertz) of
the internal oscillator’s frequency error, based on the phase accuracy error
at the beginning and end of a frequency measurement window (the length
of this window will vary depending upon the type of oscillator installed and
the oscillator adjustment algorithm).
Events panel
The Events panel in the bottom- left corner of the HOME screen is a log of
SecureSync’s recent activity. It updates in real time.
Note: If you know the individual reference or output whose status
you wish to see, you can access the Status window of that reference
or output directly through the INTERFACES > REFERENCES or
INTERFACES > OUTPUTS drop-down menu.
