USING SCOPES AS
CREATIVE TOOLS

The next two important tools―after the video monitor itself―
in analyzing a video image are a waveform monitor and vector-
scope. There are three general categories of scopes available. The
rst type is completely hardware based, with the waveform and
vectorscope trace and graticule presented on a screen built into
the scope (see Figure 3-2). The second type uses dedicated hard-
ware to display the scopes on a separate computer display or as
an overlay on your video monitor (see Figure 3-1). This is often
referred to as a rasterizer or hybrid. The third type is soft-
ware based using a video card, with the resulting image of the
scope displayed in the software UI on your computer
