Figure 3-9 is similar to Figure 3-8, except that the waveform graticule has been
zoomed to the region around 100 IRE, and the vector display has been zoomed to its
lower right quadrant.

Figure 3-10 is similar to Figure 3-8 and Figure 3-9, except that the waveform
graticule is unzoomed, and the vector area has been zoomed to its center.

Figure 3-11 shows a full-screen waveform graticule set for a 525/60 serial digital
input, but with no video signal shown. The gain is x1, and the horizontal scale is
15.0 μs per major division. The selected input is C, and the selected REF is internal.
The ON AIR status has been set to indicate that the signal is on the air, and the
SOURCE ID has been set for INPUT C, although any two lines of six characters could
have been displayed. There are no GAMUT errors, EDH is present in the serial digital
stream, and there are no DATA errors. The waveform graticule is calibrated in volts,
with dotted lines corresponding to salient points in a component test waveform.
