Normal Acquisition Mode
In Normal mode at slower time/div settings, extra samples are decimated (in other
words, some are thrown away). This mode yields the best display for most
waveforms.
Peak Detect Acquisition Mode
In Peak Detect mode at slower time/div settings, minimum and maximum samples
are kept in order to capture infrequent and narrow events (at the expense of
exaggerating any noise). This mode displays all pulses that are at least 100 ps
wide.

Glitch or Narrow Pulse Capture
A glitch is a rapid change in the waveform that is usually narrow as compared to
the waveform. Peak Detect acquisition mode can be used to more easily view
glitches or narrow pulses. In Peak Detect mode, narrow glitches and sharp edges
are displayed more brightly than when in Normal acquisition mode, making them
easier to see.
To characterize the glitch, use the markers or the automatic measurement
capabilities of the oscilloscope.
