Timestamp
The timestamp shows the time of the currently displayed history segment. Thus, the
time relation between acquisitions is always available. More precisely, the timestamp is
the time of the trigger event.
The timestamp can be absolute or relative:
●
Absolute: Date and daytime of the trigger event of the displayed segment.
Depending on the horizontal position, the waveform can be captured up to 100,000
seconds after the trigger event, and thus after the displayed timestamp. The instru-
ment considers this delay automatically, all measurements are related to the trigger
event.
●
Relative: time difference of the current segment to the newest segment (index = 0).
Remote command:

To display history segments
You can access the history segments in several ways:
●
Play back all captured history segments.
●
Play back a specified range of subsequent segments.
●
Show one particular segment.
Proceed as follows:
1. If the acquisition is running, stop the acquisition.
The history player is shown.
2. To play back the segments once, tap the Play button.
By default, all captured waveforms are shown.
3. To display a range of segments out of the history:
a) Open the "History" menu.
