PAL
For the 1741A and 1751A graticule, each PAL chrominance
vector related to the +V burst terminates in targets consisting
of two boxes (a small box inside a large box). See
Figure 4-4. The large box represents
±10° centered on the
exact chrominance phase and
±20% of chrominance ampli-
tude centered around 100% standard amplitude. The dimen-
sions of the inner target show
±3° and ±5% of chrominance
amplitude; the vectors associated with the --V burst terminate
in the smaller targets.
Dual-Standard
The 1745 and 1755 graticule is a composite of the PAL and
NTSC graticules. There are two inner targets within the
larger target; the PAL target, and the NTSC target. The
NTSC target is inside the PAL target.
