Selects the components of the trigger signal applied to the
trigger circuitry.
Overtime Trigger: In Pulse Width trigger, you may sometimes be puzzled with the long time for
trigger, as you do not need a complete pulse width to trigger the oscilloscope, but want the trigger
occurs just upon the overtime point. This is called Overtime Trigger.

Holdoff: To use Trigger Holdoff, push the HORI button and set the Holdoff Time option. The
Trigger Holdoff function can be used to generate a stable display of complex waveforms (such as
pulse trains). Holdoff is the time between when the oscilloscope detects one trigger and when it is
ready to detect another. During the holdoff time, the oscilloscope will not trigger. For a pulse train,
the holdoff time can be adjusted to let the oscilloscope trigger only on the first pulse in the train.
