Triggering

Normal
When the instrument is in nonstore mode and normal trigger mode, it
behaves in a manner similar to that of an analog oscilloscope. If a new
trigger does not occur, the instrument holds the waveform until the end
of the update period. Then the display is blanked until the next trigger
occurs.
In store mode, the instrument stores the waveform on the display until
a new trigger occurs.
AutoĆBaseline
When in autoĆbaseline mode, the instrument acquires and displays
whatever data it can capture, regardless of whether a trigger event
occurs. This mode allows you to display information even when a
signal is too small to trigger on.
If the instrument is using the scrolling timeĆbase mode for slow timeĆ
base settings, it remains untriggered because scrolling accepts no
triggers.
AutoĆLevel
In autoĆlevel mode, the instrument sets the trigger level itself. It deterĆ
mines the high and low peak values of the signal, and sets the trigger
level to the midpoint between them. If you adjust the trigger level
setting directly while in this mode and triggering is lost, the trigger level
quickly returns to the midpoint.
If no signal is applied to the trigger source, the autoĆlevel feature
causes the instrument to behave in the same manner as it does under
autoĆbaseline mode:it forces a trigger event and displays the resulting
data.
NOTE
If the instrument is using the autoĆlevel trigger mode and
you change the trigger level or the trigger is lost, the
instrument can sometimes fail to reacquire the new trigger
level. If this occurs, press the
AUTOLVL:PUSH
knob.
The instrument attempts to set the trigger level automatically when
under three conditions:
