IviScopeRuntTrigger Extension Group
In addition to the base capabilities, the IviScopeRuntTrigger extension group defines extensions for oscilloscopes with the capability to trigger on runt pulses.
A runt condition occurs when the oscilloscope detects a positive or negative going pulse that crosses one voltage threshold but fails to cross a second threshold before re-crossing the first. The figure below shows both positive and negative runt polarities.
Runt Triggers
With the IviScopeRuntTrigger extension group you can select whether a positive runt, negative runt, or either triggers the acquisition.
