PAL Vertical Scale
The PAL graticule is shown in Figure 4-2. On the left side of
the PAL graticule is a voltage scale that extends from 0 to
1.2 V. The graticules are also marked for K--Factor toler-
ances and linear-distortion measurements. These measure-
ments will be described later in this section.
Component signals can be centered on the .35 V line.

Dual-Standard Vertical Scale
The dual-standard graticule, shown in Figure 4-3, combines
the two previous scales. The 525/60 scale (NTSC) is on the
left side, and the 625/50 scale (PAL) is on the right. The
divisions represent 10 IRE in amplitude (70 mV for PAL).
