RIGOL Chapter 5 To Trigger the Oscilloscope

Trigger Holdoff
Trigger holdoff can be used to stably trigger the complex waveforms. Holdoff time is
the amount of time that the oscilloscope waits before re-arming the trigger module.
The oscilloscope will not trigger even if the trigger condition is met during the holdoff
time and will only re-arm the trigger module after the holdoff time expires. For
example, to stably trigger the repeat pulse series as shown in the figure below, the
holdoff time should be set to a value greater than T1 and lower than T2.
Figure 5-2 Schematic Diagram of Trigger Holdoff
Press MENU (in the trigger control area (TRIGGER) at the front panel)  Setting
 Holdoff; then, turn or the inner knob of the navigation knob to modify the
holdoff time at a relatively smaller step or turn the outer knob of the navigation knob
to adjust the holdoff time (the default is 100 ns) at a relatively larger step until the
trigger becomes stable. The adjustable range is from 100 ns to 10 s.
Note: For MSO2000A/DS2000A, the trigger types that support trigger holdoff
include edge trigger, pulse trigger, runt trigger, windows trigger, slope trigger, pattern
trigger, delay trigger and duration trigger.
