In Normal or Average acquisition modes, at longer horizontal time/div
settings, the oscilloscope’s analog- to- digital converter samples at a rate
that yields more samples than can be stored in a limited amount of
oscilloscope memory. Consequently, samples are thrown away (decimated),
and you can miss narrow excursions on a signal.
