The Sample acquisition mode is the default acquisition
mode. In this mode, the oscilloscope samples the signal in
evenly spaced intervals to construct the waveform.
You use the Peak Detect acquisition mode to detect
glitches and high-speed noise in fast moving signals at slow
time base settings. It is possible to miss fast glitches and
noise when the time between displayed samples is very
long.
You use the Average acquisition mode to reduce random
noise in a displayed signal. You can select the number of
waveforms to be averaged by selecting the Averages
option.
