Digital Gamut
RGB Gamut Upper/Lower
The RGB Upper and Lower alarm occurs when any component of the transcoded RGB
signal falls outside the upper or lower limits for a period in excess of the duration
setting. The Sensitivity can be increased to provide immunity to fast transcoding
spikes.

The Luma Upper and Lower alarms scan the composite encoded signal derived from
the selected digital input. The alarms occur when the luminance video falls outside the
adjustable limits for a period in excess of the duration setting. The Sensitivity can be
increased to provide immunity to fast noise spikes.
Peak Gamut Upper/Lower
The Peak Upper and Lower alarms scan the composite encoded signal derived from the
selected digital input. The alarm occurs when the peak video falls outside the
adjustable limits for a period in excess of the duration setting. The Sensitivity can be
increased to provide immunity to fast noise spikes.
