IviScopeWidthTrigger Extension Group Overview
In addition to the base capabilities, the IviScopeWidthTrigger extension group defines extensions for oscilloscopes capable of triggering on user-specified pulse widths.
Width triggering occurs when the oscilloscope detects a positive or negative pulse with a width within, or optionally outside, thresholds you specify. The figure below shows positive and negative pulses that fall within the thresholds you can specify.
Width Triggers Within the Thresholds
The figure below shows positive and negative pulses that are not within thresholds specified by you.
