Coupling refers to the type of signal coupling at the input of the
trigger circuit. Choices of trigger coupling vary by oscilloscope
model.
With DC coupling, all of the signal's frequency components are
coupled to the trigger circuit for high-frequency bursts.
4. Touch inside the trigger Slope control and choose the direction of
the trigger voltage transition used for generating a particular trigger
event.
The selection is then shown to the right of the dialog as follows for a
Positive Slope selection on an Edge Trigger.
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.
4. 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 that 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
