The waveform graticule scales change according to the video format being displayed,

as listed in Table 3-2.

Because of the large number of possible front panel control setting combinations, it is

impractical to show every possible screen display. However, the following examples

represent a cross section of what graticules and arrangements of displays can

reasonably be expected.

Figure 3-3 illustrates a full-screen waveform graticule with no signal displayed.

INPUT A has been selected, and the REF is internal. The signal standard is NTSC.

The STATUS is not ON AIR, and the SOURCE ID has been set to read INPUT A.

The SC/H phase is measured to be 0°. The vertical gain is x1, the horizontal time scale

is 5.0 μs per major division, and the FLAT (FL) filter has been selected. The -40 and

+100 IRE scale lines are indicated.
