On the Trigger dialog, select Smart trigger type, then Dropout to display the controls.

2. Choose the Slope (edge) to watch for transitions.

3. Choose the Logic Family that marks the transition threshold. To enter a custom

threshold, choose Logic Family User Defined and enter the voltage Level.

NOTE: The Logic Family will default to any Logic Setup associated with that line in a

previous digital group setup.
