DGA-6000 ULTRA-HD VIDEO GENERATOR / ANALYZER USER MANUAL
15
The HDMI standard specifies 1-254 (8-bit) and 4-1019 (10-bit) as the valid ranges for digital video
signals. For testing purposes those limits can be over-ridden using the HDMI Range item in the
Generator Misc sub-menu. Select “Full” to extend the YCbCr and RGB-Video input and output limits
to 0-255 (8-bit) and 0-1023 (10-bit). Selecting “Full” range will not change the standard video black or
reference white levels.
Field, Window, Window Border, Checkerboard, and Color User values can also be entered as
10-bit values using the USB interface. See Appendix A, the USB Interface Manual, for
additional 10-bit command formats.
Window
Size
– Select the window size for the Gray Scale, Color 75, and Color 100 group patterns from
5.0% to 20.0% in 2.5% increments. A legacy 10.8% window size is also included. The PLUGE group
window patterns are not affected.
GS
PLUGE
– Turn the PLUGE stripes in the Gray Scale group window patterns on or off. The PLUGE
group stripes are not affected.
ChkrBd
Size
– Select Checkerboard sizes from 2x2 to 9x9 for all Checkerboard patterns. A 4x4 ANSI
Standard Checkerboard is the default.
Output 1
Channels
– Enable/disable any combination of RGB or YCbCr output signal channels. This allows you to
create red, green, blue, yellow, cyan, or magenta RGB geometry, linearity, and ramp patterns, or produce
Y (luma) only signals for the color bar patterns. The former can be especially useful for adjusting
convergence in displays with separate RGB convergence controls. Not available for YCbCr 4:2:0 signals
Color Enc
– Select standard YCbCr HD/SD ITU Rec. 709/Rec. 601 color-matrix encoding, or reverse the
encoding (HD/SD Rec. 601/Rec. 709). This is useful to quickly verify correct display color decoding while
viewing color bars.
HD V Rate
– Select 59.94 or 60.00 Hz field/frame rate for HD/UHD signals.
HDMI/DVI
– Select HDMI or DVI output. Some older video monitors and computer monitors will not
display HDMI protocol signals. (Note: The DGA-6000 Analyzer function is not compatible with the older
DVI signals.)
Deep Color
– Select 8-bit RGB/YCbCr 4:4:4 digital signals, or RGB/YCbCr 4:4:4 Deep Color 10-bit or 12-
bit signal output. Only available when HDMI signal output is also selected. Not available for UHD signals.
422 Filter
– Select YCbCr 4:2:2 signal filtering On or Off. When Off is selected the Cb/Cr signals are
decimated from 4:4:4 to 4:2:2 signals without filtering. Only available when YCbCr 4:2:2 signal output is
active.
422 Bits
– Select 8-bit or 10 bit YCbCr digital video output signals. Only available when YCbCr 4:2:2
signal output is active.
Gray2Color
– Converts all non-color (gray) patterns in the Special, PLUGE, Gray Scale, and Gray Field
pattern groups to a selected color – Off (gray), Green, Blue, Red, Cyan, Yellow, or Magenta. When
Gray2Color conversion is enabled the Channels menu item is disabled, and the 422 Filter menu item is
disabled for the YCbCr 4:2:2 output mode. The Gray2Color feature is also available for 3D patterns and
the Motion Option patterns. Gray2Color is not available for YCbCr 4:2:0 signals.
