8.7.2 Pulse Width Trigger
Pulse width triggering sets the oscilloscope to trigger on the positive or negative
pulse of a specified width. In this mode, the oscilloscope will trigger when the pulse
width of the input signal satisfies the specified pulse width condition.
In this oscilloscope, positive pulse width is defined as the time difference between the
two crossing points of the trigger level and positive pulse; negative pulse width is
defined as the time difference between the two crossing points of the trigger level
and negative pulse, as shown in the figure below.
