Figure 3–3: 1780R Vector Graticule
The graticule includes four burst amplitude marks: 75% with setup,
75% with no setup, 100% with setup, and 100% with no setup.
On the NTSC graticule, each chrominance vector terminates in a
system of graticule targets in the form of two boxes (a small box
inside a large box). The dimensions of the large boxes represent
±10_ centered on the exact chrominance phase, and ±20% of
chrominance amplitude centered around 100% of standard
amplitude. The dimensions of the smaller boxes represent ±2.5_ and
±2.5 IRE.
The PAL Vector graticule is shown in Figure 3–4. On the PAL
graticule, each chrominance vector related to the +V burst terminates
in targets that are in the shape of two boxes (a small box inside a
large box). The dimensions of the large box represent ±10_ centered
on the exact chrominance phase and ±20% of chrominance
