You can use this function to display events (glitches or other asynchronous waveforms) of 50 ns (nanoseconds) or wider, or you can display HF modulated waveforms.

Suppressing High Frequency Noise

Switching Glitch Detect to Off will suppress the high frequency noise on a waveform. Averaging will suppress the noise even more.
