A runt trigger needs two thresholds to define the two levels that a signal must

pass through to be considered a valid (nonrunt) signal.

The arrow at the far right of the screen marks the threshold level(s) for that

signal.

Turning the Trigger Level knob changes the threshold level and momentarily

displays a long horizontal line (or two lines for a runt trigger) across the

waveform to show the trigger level(s) in relation to the overall waveform.
