Explanation
The following three pulse width triggers are available.
B > Time: A trigger is activated when condition B goes false after holding true for the
preset pulse width.
B < Time: A trigger is activated when condition B goes false after holding true for less
than the preset pulse width.
B Time Out: A trigger is activated when condition B has held true for the preset pulse
width.
The point where the trigger is activated differs between B > Time and B Time Out as
shown in the figure below.
When B > Time, CH1 = H, and Time = 4 µs
