Trigger modes
: There are three kinds of trigger modes available for this oscilloscope, they are, Auto
(acquires signal continuously), Normal (acquires signal when trigger conditions are met) and Single
(manually triggers the signal).
*
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 original waveform without new waveforms
captured.
*
Single 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.
*
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.
7.5. Selecting the acquisition mode
The Acquiring Mode menu is described in the list shown as below.

Description
Sample
The waveform data is sampled at an equal time interval. The sample
mode accurately reconstructs the waveform, but cannot respond to
rapid changes and sudden peaks.
Peak Detect
The maximum and minimum data in the sampling interval are picked
up. The peak detect mode captures rapid changes and sudden
peaks, but the waveform becomes noisy.
Average
Multiple samples are averaged together. The average mode reduces
the noise level, but the waveform must be repetitive.
Averages
4, 16, 64 or 128 Select the average number.
7.6. Display Setting
The Display Setting menu is described in the following table.

Description
Type
Vectors
Dots
The vector drawing mode shows the waveform as a smooth line,
connecting each data point.
The dot drawing mode shows the waveform as a collection of
independent data points.
Persist
OFF
1s
2s
5s
Infinite
The persistence setting sets how long the old waveforms remain
in the display, useful for observing the waveform variations.
