Temperature—The current board temperature will be displayed here.
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
figuring Input Reference Priorities" on page 112
STATUS: Indicates which available input reference is acting as the
erence and which available input reference is acting as the
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.
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
beginning and end of a frequency measurement window (the length of this win-
dow 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.
