Trigger conditions: Trigger and pre-trigger conditions:
Trigger=Single shot: 3000 events beginning from the start are recorded.
Trigger=Free run: At most the last 3000 events before the STOP soft key is
pressed are recorded.
Trigger condition defined: The time when recording ends depends on the
setting of the pre-trigger.
• Pre-trigger=0 %: 3000 events beginning from the fulfilled trigger
condition are recorded.
• Pre-trigger=25 % (or 50 %, or 75 %): 75 % (or 50 % or 25 %) of the
3000 events beginning from the fulfilled trigger condition are recorded.
• Pre-trigger=100 %: Recording is stopped. The last 3000 events before
the fulfilled trigger condition are recorded.
During recording, the selected signals are continuously displayed. You can
freeze the display of the signals with the DISPLAY STOP soft key. This does
not affect the recording of the signals.
The recorded data remain stored until you start recording again or activate
another graphic function.
A fulfilled trigger condition is indicated with a "T" in the status field at right
below the display area.
Hide/show gridlines:
Press the GRID soft key.
If the trigger condition is fulfilled before the corresponding number of
events have been stored when the pre-trigger is set to 25 %, 50 %, 75 %
or 100 %, then correspondingly fewer events are recorded.
