Say I set the scope to average 256 traces. During the accumulation of these traces, say a square wave, the waveform gets sharper and sharper and the horizontal sections get down to only 1 pixel wide. Then when the 256 count is reached the horizontal sections of the trace are dithered between adjacent pixels! While this may be mathematically correct is just makes the waveform look fuzzy - the very thing you are trying to avoid by using averaging mode. Looks great while the average count is going up, but not as good once the average count is reached. Very annoying! Is this your experience on your scope?
