DGA-6000 ULTRA-HD VIDEO GENERATOR / ANALYZER USER MANUAL

Introduction: Versatile, Accurate, Easy-to-Use

The AccuPel DGA-6000 Ultra-HD Video Generator / Analyzer is a professional test equipment device

exclusively for commercial or industrial calibration, testing, and design of HDMI® video displays, sources

and processors. It is not designed or intended for testing computer graphics formats or computer monitors,

or to be embedded in consumer video systems.

Two Independent Test Equipment Devices in a Single Product

The DGA-6000 is a 4K Ultra-HD Video Generator and a 4K Ultra-HD Video Analyzer, and both functions are

HDR and Rec. 2020 compatible. The Generator and Analyzer can be used independently to test video

sources and video displays, or together to test or calibrate video processors. The Video Generator can be

operated from the DGA-6000 front panel, the AccuPel DGA-6 IR Remote Control (included), or the USB

interface that is shared with the Video Analyzer. The Video Analyzer human interface utilizes InfoPanes

(Information Panes) that overlay the Analyzer’s incoming video, which is then displayed on the Analyzer’s

monitor. Analyzer functions are primarily controlled from the DGA-6 Remote Control.

DGA-6000 Ultra and Pro Engineering Option

The DGA-6000 Ultra provides UHD/HD/SD video pattern generation and per-pixel video content analysis

(RGB/YCbCr pixel values with a unique Magnified Pixel Viewport). The Pro Engineering option adds 70

UHD/HD/SD Motion Patterns to the generator that can be used to evaluate displays and video processors,

and additional advanced video analyzer features including live Min/Max/APL metering, Timing

measurements, InfoFrame protocol analysis, and more.

26 Versatile 2D Digital Video Formats with 5 Output Signal Types

The DGA-6000 Ultra generates and analyzes 26 2D digital video formats compliant with CTA-861-F

including 480i/p, 576i/p, 720p50/59.94/60, 1080i50/59.94/60, 1080p23.98/24/25, 1080p29.97/30,

1080p50/59.94/60, 2160p23.98/24/25, 2160p29.97/30, and 2160p50/59.94/60.

All formats except 2160p50/59.94/60 are available as YCbCr 4:4:4, YCbCr 4:2:2, RGB-Video, and RGB-PC

output signals. The 2160p50/59.94/60 formats are available for YCbCr 4:2:0 output.

33 Additional 3D Digital Video Generator Formats

The DGA-6000 generates 33 additional 3D signal formats. Each 3D signal format is a combination of an

industry-standard 3D structure (Frame Packing, Side-by-Side (Half), or Top-and-Bottom) and a specific

video format (e.g. 1080p24). All 3D formats that industry-conforming 3D display devices are required to

accept are included, plus additional 3D formats used for Blu-ray Disc playback and for cable and satellite

broadcast distribution.

DGA-6000 ULTRA-HD VIDEO GENERATOR / ANALYZER USER MANUAL

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.

Maximum Accuracy Direct-Drive Digital (D3)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.
