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. 

 

 

 Figure 4-12. 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. 

L

EVEL

 

Level

 defines the source voltage at which the trigger circuit generates an 

event (a change in the input signal that satisfies the trigger conditions).
