Temperature
—The current board temperature will be displayed here.
Reference Status panel
REFERENCE
: Indicates the name type of each reference. These are determined by
the inputs set up for the VelaSync
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
Input Reference Priorities" on page 112
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 cur-
rently valid.
Performance panel
Disciplining State
—Indicates whether or not the internal oscillator is currently
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 ref-
erence has excessive 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 begin-
ning 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 VelaSync’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 dir-
ectly through the INTERFACES > REFERENCES or INTERFACES >
OUTPUTS drop-down menu.
