RIGOL Chapter 5 To Trigger the Oscilloscope

Duration Trigger
In duration trigger, the instrument 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 H (high), L (low), or X (don't care). When the
duration (â–³T) of this pattern meets the preset time, the oscilloscope initiates a
trigger, as shown in the figure below.

trigger source, can we obtain a stable trigger.
