Averaging Mode
The Averaging mode lets you average multiple acquisitions together to
reduce noise and increase vertical resolution (at all sweep speeds).
Averaging requires a stable trigger.
The number of averages can be set from 2 to 65536 in powers- of- 2
increments.
A higher number of averages reduces noise more and increases vertical
resolution.
The higher the number of averages, the slower the displayed waveform
responds to waveform changes. You must compromise between how quickly
the waveform responds to changes and how much you want to reduce the
displayed noise on the signal.
