Acquisition Modes
There are two acquisition modes: Normal, Average.
Normal: In this acquisition mode, the oscilloscope samples the signal in evenly spaced intervals to construct the
waveform.
Average: In this acquisition mode, the oscilloscope acquires several waveforms, averages them, and displays the
resulting waveform. You can use this mode to reduce random noise.

Interpolation
At the time base 50ns/div or faster, user can click “Acquire->Interpolation” to select 3 different interpolation modes
to get waveforms of different smoothness.
The Step Interpolation:
The Linear Interpolation:
