User Manual

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.
7.5 Acquiring Mode Setting
The Acquiring Mode menu is described in the list shown as below.

Peak Detect Used to detect the jamming glitch and reduce the possible blurring.
Average
Used to reduce the random and unrelated noises. Several average
factors are available for being selected.
