Trigger Settings
Horizontal and Vertical adjustments are typically made for all trigger types
using either the Delay or Level knobs on the front panel of the instrument
or their respective controls on the Timebase setup dialog.

Horizontal: Turn the D ELAY knob in the HORIZONTAL control group
to adjust the trigger's horizontal position. Or, touch inside the Delay
control and provide a value on the Timebase dialog using your
preferred input control method. Additional information on using the
touch screen controls can be found in the Dialog Area (on page 33).
The trigger location is shown by a marker under the grid.
Post-trigger delay is indicated by a left-pointing arrow at the lower-
left of the grid.
The time value is given in the title line of the Timebase label at the
lower-right of the grid.

Vertical: Turn the L
EVEL
knob in the TRIGGER control group to adjust
the trigger's vertical threshold.
Turn this knob to adjust the level of the trigger source or the
highlighted trace. Level defines the source voltage at which the
trigger will generate an event: a change in the input signal that
satisfies the trigger conditions.
Alternatively, in the Trigger dialog, you can touch inside the Level
control and provide a value using your preferred input control
method. Additional information on using the touch screen controls
can be found in the Dialog Area (on page 33). Quickly set a level of
zero volts by touching the Zero Level button.
An arrow on the right side of the grid shows the threshold position.
This arrow is only visible if the trigger source is displayed.
