a. When used with color bar signals, the vectorscope produces a pattern of
lines and dots which indicate the vectors corresponding to the various colors. The
pattern appears as bright dots linked by relatively faint lines. As illustrated in
Figure 3-35, boxes may be drawn on the oscilloscope face to indicate phase and
amplitude tolerances.
