of 64 acquisitions.

average, see below)
You can use the average functions to suppress random or
uncorrelated noise in the waveform without loss of
bandwidth. Waveform samples with and without smoothing
are shown in Figure 9.
Smart average
In the normal average mode occasional deviations in a
waveform just distort the averaged wave shape, and do
not show up on screen clearly. When a signal really
changes, for instance when you probe around, it takes
quite some time before the new wave shape is stable.
With smart averaging you can quickly probe around, and
incidental waveform changes like a line flyback in video
show up on screen instantly.
