3.3.2.3 Edge
The edge trigger is the simpliest and most common trigger type. It is well-known from
analog oscilloscopes; and you can use it for analog and digital signals. The trigger event
occurs when the signal from the trigger source passes the specified treshold voltage -
the trigger level - in the specified direction (slope).
The edge trigger is also selected with the AUTOSET function.
