DGA-6000 ULTRA-HD VIDEO GENERATOR / ANALYZER USER MANUAL
4
All DGA-6000 2D test patterns are available in all 33 3D video formats. All 3D formats are available in 10-bit
native (and 8-bit native) YCbCr 4:2:2, and Deep Color (10-bit native) and 8-bit native YCbCr 4:4:4, RGB-
Video, and RGB-PC output modes. A special interactive 3D Crosstalk Measurement Test Pattern is also
included.
Separate High-Precision 10-Bit (30-Bit RGB/YCbCr) & 8-Bit (24-Bit RGB/YCbCr) Signal Values
To provide maximum accuracy, Luma and Chroma values for ITU Rec. 601 (SD), ITU Rec. 709 (HD), and
ITU Rec. 2020 are computed using 64-bit double-precision floating-point math and then rounded to 8-bit and
10-bit values. Separate 10-bit and 8-bit component video values are stored for all 115 standard patterns to
eliminate accuracy errors that could occur when rounding, truncating, or dithering 10-bit output values to
create 8-bit output values. All non-color patterns, including 3D and the optional Motion Patterns, can also be
output as YCbCr green, blue, red, cyan, yellow, or magenta patterns by selecting Gray to Color Conversion
(not available for YCbCr 4:2:0 formats), or by selecting R, G, B channel combinations.
RGB-Video, RGB-PC, and YCbCr 4:4:4 10-bit component video values are output by selecting the 30-bit or
36-bit Deep Color output modes. Users can also select 10-bit or 8-bit YCbCr 4:2:2 (20-bit/16-bit) output.

Pattern Generation
For maximum timing accuracy and minimum jitter all video patterns, digital sync, and timing signals are
generated using a low-noise, high-stability, precision crystal oscillator. No format converters or frame buffers
are used to ensure maximum signal timing accuracy.
A custom-programmed pattern and timing generation FPGA directly drives an HDMI digital video output
transmitter with 30-bit and 24-bit RGB/YCbCr video values depending on output signal type. There’s no
digital signal truncation or dithering in the digital video path that would reduce bit-level accuracy.
Easy-to-Use Infrared Remote Control
The 41-key, DGA-6 IR remote control provides maximum ease-of-use for standalone Generator operation,
and is the primary user controller for Analyzer functions. Dedicated keys are provided to directly select
Output modes, Format modes, and Pattern Groups. There are also dedicated keys to move forward or
backward through Groups or Patterns. Pattern switching is virtually instantaneous because patterns are
generated in a custom-programmed FPGA, and not loaded into a frame buffer from memory. A user-defined
Pattern List provides another easy way to switch between favorite patterns. Single key pushes will store or
delete up to 10 patterns in the Pattern List, and move forward or backward through the Pattern List.
The IR remote control also provides keys to enter 10-bit, 8-bit, or % user-defined Luma and Color values,
navigate On-Screen-Display (OSD) menus, and operate cursors and all Analyzer features.
OSD Menus
OSD (On-Screen-Display) menus provide access to advanced Generator and Analyzer features including
the ability to select HDR output, select Rec 2020 color-encoding, specify user-defined Luma and Color
values, select window and checkerboard sizes, set output bit-depth, blank individual R/G/B/Y/Cb/Cr output
channels, set power-up default modes, configure the USB interface, select Analyzer functions, and much
more.
USB Control Interface
The USB Control Interface provides full operation of all DGA-6000 functions, including direct selection of
every pattern. Detailed documentation for the USB Interface is included in Appendix A of this manual.
