8-Advanced Function of Oscilloscope
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 until 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.
8.5 Setting the Acquiring Mode
The ACQU MODE menu is described in the list shown as below.
Sample
The waveform data is sampled at an equal time interval. The
sample mode accurately reconstr
ucts the waveform, but cannot
respond to rapid changes and sudden peaks.
Peak Detect
T
he maximum and minimum data in the sampling interval are
picked up. T
he peak detect mode captures rapid changes and
sudden peaks, but the waveform becomes noisy.
Average
Multiple samples are averaged together. T
reduces the noise level, but the waveform must be repetitive.
Averages
4, 16, 64
or 128
Select the average number.
8.6 Display Setting
The DISP SET menu is described in the following table.
Type
Vectors
Dots
T
he vector drawing mode shows the waveform as a smooth line,
connecting each data point.
T
he dot drawing mode shows the waveform as a collection of
independent data points.
Persist
OFF
1sec
2sec
5sec
Infinite
The persistence setting sets how long the old waveforms remain
in the display, useful for observing the waveform variations.

The data transmitted in communication are bitmaps.
