Upper chroma alarm limit Displayed as Upper = xxx yy.
For RGB xxx is the RGB Gamut upper threshold setting
and yy is shown as mV.
For Composite, xxx is the Peak upper threshold setting.
In Composite, yy is determined by the format (IRE for
NTSC and Units or mV for PAL).
6
Lower chroma alarm limit Displayed as Lower = xxx yy.
For RGB xxx is the s the RGB Gamut lower threshold
setting, and yy as units.
For Composite, xxx is the Peak lower threshold setting.
In Composite, yy is determined by the format (IRE for

in Table 3-20, is two concentric circles with other identifiers. When setting the upper
and lower limits, the upper and lower gamut rings represent the values set from the
threshold values of the appropriate format. Set the 525 or 625 (check format) threshold
in the VIDEO ALARMS DIGITAL\DIGITAL GAMUT\PEAK GAMUT
(UPPER/LOWER) menu to move the gamut rings or LUMA GAMUT
(UPPER/LOWER)\THRESHOLD 525/625 menu to move the luma bar limits. The
