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).

Remote command: 

CHANnel<m>:HISTory:TMODe

, 

on page 509

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".

Play

Starts and stops the playback of the history segments.

Remote command: 

...:HISTory:PLAYer:STATe

Prev.

Steps back to the next older segment.

Next

Steps forward to the next newer segment.

Repeat

If selected, the playback of the selected history segments repeats automatically.

Remote command: 

...:HISTory:REPLay

Speed

Sets the speed of the history playback: automatic, slow, middle, or fast.

Remote command: 

...:HISTory:PLAYer:SPEed
