Note:
Trigger Holdoff can stabilize complex waveform, such as the pulse range. Holdoff time is the
oscilloscope’s waiting period before starting a new trigger. During Holdoff, oscilloscope will not
trigger until Holdoff ends.

Term interpretation
Trigger modes
: There are three kinds of trigger modes available for this oscilloscope, they are
auto, normal and single shot.

Automatic trigger mode: The oscilloscope can acquire the waveform without any triggering
condition detected in this mode, in which it will be triggered compulsively when waiting for a
specified period of time without any triggering condition ignited When an invalid trigger is
enforced,the oscilloscope can not keep the waveform in phase.

Normal trigger mode: In this mode, the oscilloscope cannot acquire the waveform till it is
triggered. When there is not any trigger, the oscilloscope will display the origin waveform without
new waveforms captured.

Single shot mode: In this mode, the oscilloscope will detect a trigger and capture a waveform at
each time when the customer presses the RUN/STOP key.

Holdoff: Set time slot before another trigger event.
