Acquisition Mode
The acquisition mode is used to control how to generate waveform points from
sample points.
Press Acquire  Acquisition in the function menu at the front panel and use
to select the desired acquisition mode (the default is normal), then press down the
knob to select this mode. You can also press Acquisition continuously to switch the
acquisition mode.
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. More
averages can lower the noise and may increase the vertical resolution but it will slow
the overall response of the displayed waveform to input changes.
The available range of the number of averages is from 2 to 8192 and the default is 2.
When “Average” mode is selected, press Averages and use to set the desired
number of averages as the power function of 2.
