RIGOL Chapter 5 To Trigger the Oscilloscope
5-18 DS8000-R User Guide
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.
Figure 5-7 Duration Trigger
Trigger Type:
Click Type to select "Duration". Then, the current trigger setting information is
displayed at the upper-right corner of the screen, as shown in the figure below.
Source Selection:
Click Source to open the signal source list and select CH1-CH4. For details, refer to
descriptions in "Trigger Source". The current trigger source is displayed at the
upper-right corner of the screen.
Note: Only when we select the channel (that has been input with signals) as the
trigger source, can we obtain a stable trigger.
