What Is a Glitch Trigger?

Glitch triggering is only available in the LabVIEW or C API. A glitch is a signal that has the same state at two different sample clock edges but transitioned in between. This is only possible to detect if your sample clock rate is less than 1 GHz. If your digital sample rate is 1 GHz, then a glitch trigger condition will never be met.

Since the signal maintains state during the sample period, a glitch is not visible in the data.

The following figure shows both positive and negative glitches.
