1 PPS Analysis Results
The 1PPS Analysis category provides results describing the offset analyzed signal as
compared to the reference signal.
Table 13 describes the results.
A TIE graph is also available that shows the current time interval error.
ToD Results
The ToD Results category provides ToD results associated with the reference signal
and the analyzed signal as shown in
Table 14 .
Table 14 ToD Results.
Oscillator Mode The current mode of the oscillator (Warm Up,
Coarse Tune, Fine Tune, or Holdover).
