these digressions are above or below the allowable limits. The inputs are shown as an
encoded display with gamut alarms. The displays show RGB and composite video
limits.
Vector excursion marks are shown in the gamut display. The excursion marks help to
visualize the minimum/maximum value of a 100% color bar signal. The position of the
excursion marks depend on the selected Video Format selection from the Video Setup
menu.
