To capture glitches or narrow pulses with peak detect and infinite 
persistence

A glitch is a rapid change in the waveform that is usually 
narrow as compared to the waveform. Peak detect 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 acquire mode, making them 
easier to see.

To characterize the glitch, use the cursors or the automatic 
measurement capabilities of the oscilloscope.
