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, with an
accuracy of 1 ms.
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:
●
CHANnel<m>:HISTory:TSABsolute? on page 351
●
CHANnel<m>:HISTory:TSDate? on page 351
●
CHANnel<m>:HISTory:TSRelative? on page 352
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.
b) Set the index of the first and the last segment that you want to see.
See "Start Acquisition / Stop Acquisition" on page 100.
c) In the history player window, tap the Play button.
4. To play back the segments repeatedly.
a) Enable the "Repeat" button.
b) Tap the "Play" button.
5. To access a particular segment, you can:
● Drag the slider in the history player window until the required index number.
● Use the "Step Forward" and "Step Back" buttons to show the next segment.
