•
Select PIXEL to generate and receive pseudo-random noise at every pixel within
the whole frame.
•
Select ACTIVE PIXEL to generate and receive pseudo-random noise only at active
pixels within the frame.
8. Using the
Format
knob, select the
Parameters
field.
9. Using the
Image
knob, specify how you want the pseudo-random noise seed and
sequence length implemented, as follows:
•
Select AUTO to use the default seed value and sequence length. The default
settings ensure a stable, pseudo-random noise image. If you select this setting,
proceed to step 11.
•
Select MANUAL to define specific seed value and sequence length settings. If you
select this setting, proceed to step 10.
Note: If the HDMI/DVI signal source is external (Auto Based On field set to
MEASURED
), you cannot manually define these settings. The Parameters and Seed
Value(Hex) fields appear dimmed, and the Run Length(Hex) field is set when
measuring the external signal’s timing parameters (see “
10. If you set the
Parameters
field to MANUAL, define specific settings for pseudo-random
noise seed and sequence length by following these steps:
a.
Using the
Format
knob, select the
Seed Value(Hex)

d.
Specify the desired sequence length value in hexidecimal (if
Run-Length(Hex)
field is highlighted) or decimal (if
Run-Length(Dec)
field is highlighted) using the
cursor (displayed under a digit in the field) to select the appropriate value as
follows:
•
To move the cursor between digits, use the
R
and
G
keys.
•
