• Width Trigger <For the setup procedure, see section 6.11>
A trigger is activated by determining whether the time width over which the specified
condition is met or not met is shorter or longer than the determination time width set in
advance. The condition is set on the AND logic of the status (High, Low, or Don’t
Care) of each channel or the AND logic of the window condition (IN, OUT, or Don’t
Care) of each channel.

Determination Type Results
Pulse <T Trigger is activated at point B.
Pulse > T Trigger is activated at points A and C.
T1 < PLS < T2 When set to Time1 = 350 and Time2 = 450 ns, the trigger activates at
point C.
Time Out When set to Time1 = 450, the trigger activates at point D.
