Navigate to MANAGEMENT > OTHER: Disciplining .
The Oscillator Management screen will display. It consists of two panels:
Oscillator Type : Type of oscillator installed in the unit.
Disciplining State : State of oscillator control and disciplining; indicates whether or not the
internal oscillator is currently being disciplined (steered to an input reference). The states
are: "Warm up", "Calibration", "Tracking Setup", "Lock State", "Freerun", and "Fault".
1PPS Phase Error : A tracking measurement [scaled time, in ns, or ms] of the internal
1PPSs' phase error with respect to the selected input reference. Long holdover periods
or an input reference with excessive jitter will cause the phase error to be high. The oscil
lator disciplining control will gradually reduce the phase error over time. Alternatively,
restarting the tracking manually (see "Restart Tracking" under "Configuring the Oscil
lator" on page 196), or automatically via a pre-set Phase Error Limit, will quickly reduce
the phase error.
: An internal estimated calculation (in Hertz) of the internal oscil
10 MHz Frequency Error
lator'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).
