cTE Averaging Period (s)
defines the averaging period used to
calculate the constant Time Error (cTE) value over a specific period of
time:
Elapse time
(default),
100 s
,
500 s
,
1000 s
,
10000 s
.

H
Observation Period (s) 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).

Cable Delay Compensation (ns)
, available for time error
measurements, allows manual compensation of external cable delay
asymmetry: -
1000 ns
to
1000 ns
(
0 ns
by default).
The cable delay asymmetry is caused by the difference between the
length of the cable feeding the reference signal and the one feeding
the signal under test. For example to compensate for a cable delay of
-39 ns, enter this measured value as the
Cable Delay Compensation
:
-39 - (-39) = 0 ns .

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 ).
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.
