Time Error / Wander
 Duration check box when selected (cleared by default) allows
selecting/entering the test duration: 15 minutes, 1/2/4/6/12/24/72
hours, or User Defined (1 second up to 30 days depending on the
selected Sampling Rate); with the G.8275.2 profile, the duration
should be more than 200 seconds in order to obtain TE values.
Note: Once the test completes (after the duration is reached or when manually
stopped), MTIE calculation may take some time depending on the test
duration and sampling rate used.
For Time Error measurements:
 cTE Averaging Period (s), available with either G.8275.1 profile or
1PPS interface, defines the averaging period used to calculate the
constant Time Error (cTE) value over a specific period of time: Elapsed
time (default), 100 s, 500 s, 1000 s, 10000 s.
 dTE
H
Observation Period (s), available with either G.8275.1 profile or
1PPS interface, defines the observation period used for qualifying the
Time Error after High-Pass filtering 0.1 Hz: 100 s, 500 s, 1000 s, 10000 s
(default).
