To display history segments
1. Activate the history.
2. Stop the acquisition.
3. Set the "Time Format" to be shown in the table: absolute or relative time.
4. Set the "Speed".
5. To play all segments once, tap "Run".
6. To play all segments repeatedly:
a) Enable the "Repeat" button.
b) Tap "Run".
7. To access a particular segment, you can:
● Tap the segment in the segment table.
● Drag the slider until the required segment number is shown.
● Tap "Number" and enter the segment number. The newest segment has always
the number "0". Older segments have a negative number.
● Use "Prev." and "Next" to show the adjacent segment.
8. If the history segments contain the data of several channels and you want to ana-
lyze only one or several channels, disable all channels that you do not need.
Functions in the segment table and history player
Time Format
Sets the format of the timestamp. The timestamp shows the time of the currently dis-
played history segment. Thus, the time relation between acquisitions is always availa-
ble. 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).

Chapter 15.6.5.3, "Timestamps"
Save
Saves the segment table to a CSV file on a connected USB flash drive. The file con-
tains all timestamps: relative time, time to previous, and absolute time. To save the
waveform segments, use [Save Load] key > "Waveforms".
