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 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.
