Pattern Selection
There are three methods of selecting patterns – sequential group and pattern selection, direct selection by
group and pattern # (number), and user-defined pattern lists.
Sequential Group & Pattern Selection
Group
Press the top of the Group rocker button to move forward to the
next pattern Group. Press the bottom of the Group rocker button
to move backward to the previous pattern group.
Pattern
Press the top of the Pattern rocker button to move to the next
pattern in the current pattern group. Press the bottom of the
Pattern rocker button to move to the previous pattern in the
current pattern group.
Direct Group & Pattern Selection
Color75, Color100, Special, PLUGE, Gray Scale, Gray Field
-
Directly select one of the 6 major pattern groups.
ALT Gray Scale
– Press this button combination to select or
alternate between 0%-10% Low-GS (Gray Scale) patterns and
100%-109% High-GS patterns. Press the Gray Scale button only
to return to the default 0%-100% Gray Scale patterns. The Gray
Scale LED will blink slowly when the Low-GS or High-GS mode
is enabled.
Note: The background of the High-GS windows is 100% luma to
examine a display’s ability to differentiate levels near 100%.
Note: 100%-109% patterns are not available for digital RGB-PC
signals because the maximum signal amplitude is 100% (digital
255) for RGB PC signals.
Pat #
Press the Pat # button followed by a number button (0-10) to
directly select a pattern in the current pattern group. The active
Group LED will flash while waiting for the number button to be
pressed. Press any other button to cancel the Pat # entry
process.
This function is primarily useful to quickly select a specific
grayscale window value in the Gray Scale group. Pattern #1
selects the 10 IRE window, pattern #2 selects the 20 IRE
window, … pattern #10 selects the 100 IRE window. When the
1%-10% Grayscale pattern group is enabled, pattern #1 selects
the 1 IRE window, pattern #2 selects the 2 IRE window, etc. The
Pat # table on the next page shows the pattern #’s for all groups.
