Basic Measurements

Vector Graticule

The VECTOR display permits measurements of hue in terms of the relative phase of the chrominance signal with respect to the color burst. Relative amplitude of chrominance to burst is expressed in terms of the displacement from center (radial dimension of amplitude).

The vector graticule is combined with the waveform grati- cule.

The NTSC and PAL vector graticules contain burst and vector targets; the dual-standard graticules contain burst and vector targets for both NTSC and PAL standards. The vector targets can be used with either 75% or 100% amplitude color bar signals. The selection is made through the

TOR menu, described on page 3-18.

NTSC

The chrominance vectors terminate in a system of graticule targets consisting of two boxes (a small box inside a large box). A sample target is shown in Figure 4-4. The dimensions of the large boxes represent ±10° centered on the exact chrominance phase, and ±20% of chrominance amplitude centered around standard amplitude. The dimensions of the smaller boxes represent ±2.5° and ±2.5 IRE.
