Chapter 4 Sample System Setting

Normal

In this mode, the oscilloscope samples the signal at equal time interval to rebuild the
waveform. For most of the waveforms, the best display effect can be obtained using
this mode.

Average

In this mode, the oscilloscope averages the waveforms from multiple samples to
reduce the random noise of the input signal and improve the vertical resolution.
When "Average" mode is selected, press Averages and turn the multi-function knob
to increase or reduce the number of averages. The numbers of averages
available include 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096 and 8192. The
default is 2. More averages can lower the noise and increase the vertical resolution;
but, it will slow the response of the displayed waveform to the waveform changes.

The waveform after 256 averages:
