15.5.2 Edge Trigger
Edge trigger distinguishes the trigger points by seeking the specified edge (rising, falling, alternating)
and trigger level. The trigger source and slope can be set in the trigger dialog box.
Touch the Source area to select trigger source, and touch the Slope area to select rising, falling,
or alternating.
Rising -- Only trigger on the rising edge
Falling -- Only trigger on the falling edge
Alternating -- Trigger on both rising edge and falling edge
Holdoff, coupling, and noise reject can be set in edge trigger, see the sections "Holdoff", "Trigger
Coupling" and "Noise Reject" for details.
Note: Press the Auto Setup button, and the oscilloscope will set the trigger type to Edge.
15.5.3 Slope Trigger
The slope trigger looks for a rising or falling transition from one level to another level in the specified
time range. For example, positive slope time is defined as the time difference between the two
crossing points of trigger level lines A and B with the positive edge as shown in the figure below.
Touch the Source area to select trigger source, and touch the Slope area to select rising or
falling.
