Acquisition Modes
There are two acquisition modes: Normal and 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, aver-
ages them, and displays the resulting waveform. You can use this mode to reduce
random noise.
ETS:In this acquisition mode, you can test high frequency cycle signal.
