Using Scopes as Creative Tools
Pages 44

The next two important tools-after the video monitor itselfin analyzing a video image are a waveform monitor and vectorscope. There are three general categories of scopes available. The first 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 hardware 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 software based using a video card, with the resulting image of the scope displayed in the software UI on your computer monitor (see Figure 3-3).
