980 DP 1.4 Video Generator / Analyzer - User Guide
Some test patterns have multiple versions such as GraysAll. These multiple versions can be applied using the
Rendition button and associated dialog box as shown below. There is a default that is iteration 0. In the
example below iteration 2 is currently being rendered on the sink DUT.
5. Set the luminance level of the image with the Level button. The associated dialog box is shown further below.
You can increment the color component values or can decrement the color component values for all pixels of
any image through the front panel or the command line. This feature enables you to increment or decrement
the values in increments (or decrements) of 1 throughout a range of 0 to 255. The LEVP feature increments or
decrements all color component values (R,G,B) for each action by the use.
6. Set the pixel depth (PELD) if necessary through the Level button and associated dialog box shown above.
PELD establishes the number of data bits that represent each active pixel in video memory (frame buffer).
Parameter. The default setting and setting of 8 allows 256 colors on an image (test pattern) to be rendered.
This is suitable for the majority of test patterns. However, some test patterns contain more colors and either
require PELD 32 or look optimal only when PELD is set to 32. The test pattern will indicate when PELD 32
setting is required.
Default - uses the 980 video generator default
8 - 8 bits-per-pixel (256 colors)
24 - 24 bits-per-pixel (16,777,216 colors).
7. Set the pattern parameters if necessary through the Params button and associated dialog box shown below.
The following table describes each parameter.
