A vectorscope is more accurate than a waveform monitor. Figure 23 shows an
example of a vectorscope display when the horizontal phase is adjusted to align it
with the burst (genlock) vector. Adjust the horizontal phase until the difference

between the two vectors is 0º. This example shows black burst only (with no color).
The burst vector is pointing to the left from the center.

Figure 24 shows an example of a view of a vectorscope during adjustment of the
color subcarrier phase. The subcarrier phase should be aligned to 0º (indicated in
the figure by the triangle).
