8.2.1.1. Video Pattern Generator

The video pattern generator generates a colorbar or pathological pattern. The colorbar is preferable for image generation while the pathological pattern can stress the PLL and cable equalizer of the attached video equipment. You can configure the video pattern generator to generate various video formats.

Table 26.  Configuring the Video Pattern Generator to Generate Different Video FormatsTable below lists the examples of how to configure the video pattern generator signals to generate a video format that you desire.
Example Video Format Interface Signal
