4
Line select information
Shown as Line and the number with the Odd or Even field
(when applicable)
5
Reference
Displays the reference as INT, EXT (toggled by pressing
the REF button)
6
Lower luma alarm limit
(Composite only)
Displayed as Lower = xxx yy;
xxx
is the Luma lower
threshold setting and
yy
is determined by the format (IRE
for NTSC and Units or mV for PAL)
7
Upper luma alarm limit
(Composite only)
Displayed as Upper = xxx yy;
xxx
is the Luma upper
threshold setting and
yy
is determined by the format (IRE
for NTSC and Units or mV for PAL)
8
Luma alarm limit
Displays Luma when Composite is selected; this field is
blank when Single Color or
RGB is selected
9
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
NTSC and Units for PAL)
10
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)
11
Chroma alarm limits
Displayed as RGB (for RGB or Single Color) and PEAK (for
Composite)

Composite or RGB Gamut graticule
Composite Gamut
The graticule for the composite gamut vector, as shown in
Figure 4-22
and described
in Table 4-6
, 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. To move the gamut rings, set the

THRESHOLD 525/59.94 or THRESHOLD 625/50 selection option. The
outer circle (the upper gamut alarm limit) represents the highest allowable amplitude in
standard composite units (that is, IRE for NTSC and units for PAL). The inner circle
(the lower gamut alarm limit) represents the lowest allowable amplitude. The rings turn
red when the alarm is enabled and the values exceed the threshold setting.
The other identifiers are radials that extend at the angle of the designated color. These
six lines follow the same displacement as the vector display. Note that since the PAL
display is derived solely from component information, there are not two phases for
PAL signals. The +V phase is used (making the vectors look similar to NTSC).
