For Internal triggering, the waveform trigger icon
identifies the level and moves as you make the level
adjustment. The actual trigger level is displayed in
the upper right corner of the display. For Dual
triggering, you must first select which trigger point
you want to adjust with the
1
Slope selection.
The waveform icon will move from one point to the
other in the display as the slope selection is
changed. The counter trigger levels are linked with
the waveform trigger levels in dual triggering and are
the only time they can be manually set. For external
triggering, a single trigger level is set with the (
[
and

) softkeys and is indicated in the special
trigger level indicator in the upper right corner of the
display. There are 21 different preset trigger levels
available for external triggering.
If “Full Auto” is selected, the trigger levels are set on
percentages of the input signal.
