8.7.6 Duration Trigger
In duration trigger, the oscilloscope identifies a trigger condition by searching for the
duration of a specified pattern. This pattern is a logical "AND" combination of the
channels. Each channel can be set to 1 (high), 0 (low), or X (don't care). The
instrument triggers when the duration (∆T) of this pattern meets the preset time, as
shown in the figure below.
