A glitch trigger occurs when a pulse that crosses a vertical threshold you specify and with a polarity you specify also has a width that is either greater than or less than a duration you specify. The oscilloscope can trigger on pulses of positive, negative, or either polarity.

Use the glitch trigger to detect transient pulses within pulse trains.

You can configure the glitch parameters in NI‑SCOPE using the Analog Glitch Ref Trigger instance of the Configure Trigger (poly) VI.

The following figure illustrates glitch triggering.
