NTP —Current STRATUM status of this SecureSync unit.
Temperature —The current board temperature will be displayed here, plus—depending
on product configuration—oscillator, and CPU temperatures, as well. For more inform
ation, see "Temperature Management" on page 281.
REFERENCE : Indicates the name type of each reference. These are determined 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 page 157 for more information.
STATUS : Indicates which available input reference is acting as the Time reference 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.
PHASE : The measured time interval error ("TIE") between the internally disciplined 1PPS
and the selected external 1PPS reference.
Disciplining State —Indicates whether or not the internal oscillator is currently being dis
ciplined (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 excess
ive jitter, phase error will be higher)
10 MHz 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).
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.
