Edge trigger works on the selected edge at the chosen level. The slope
(positive or negative) is specified on the Trigger label permanently shown
to the lower-right of the grid.
5. Level defines the source voltage at which the trigger circuit
generates an event (a change in the input signal that satisfies the
trigger conditions). The selected trigger level is associated with the
chosen trigger source.
Note: The trigger level is specified in volts and normally remains
unchanged when the vertical gain or offset is modified. The
Amplitude and Range of the trigger level have limits as detailed in
the datasheet specifications regularly maintained on
teledynelecroy.com.
Touch inside the Level data entry control and provide a voltage level
(in millivolts).
PLEASE NOTE THE FOLLOWING:

Once specified, Trigger Level and Coupling are the only parameters
remaining unchanged as you switch from trigger mode to trigger
mode for each trigger source.

Some additional controls and dialogs for triggers that differ are
provided in the following topics as examples.
