Introduction
Separate High-Precision 10-Bit & 8-Bit Signal Values
To provide maximum accuracy, Luma and Chroma values for ITU Rec. 601 (SD)
and ITU Rec. 709 (HD) 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 113 basic pat-
terns to eliminate accuracy errors that occur when rounding, truncating, or dither-
ing 10-bit output values to create 8-bit output values.
RGB-Video, RGB-PC, and YCbCr 4:4:4 10-bit 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 individual low-noise, high-stability, precision
crystal oscillators for standard-definition, 59.94 Hz high-definition, and 50/60 Hz
high-definition video formats.
A proprietary AccuPel pattern and timing generation IC directly drives the HDMI
digital video output transmitter with 30-bit and 24-bit RGB/YCbCr video values
depending on output signal type. There is no digital signal truncation, dithering, or
color-matrix conversion in the 30-bit or 24-bit digital video path that would reduce
bit-level accuracy. No clock synthesizers, format converters, or frame buffers are
used to ensure maximum signal timing accuracy.
Easy-to-Use Infrared Remote Control
A 41-key IR remote control is standard to provide maximum standalone ease of
use. Dedicated keys are provided to directly select each Output mode, Format
mode, Pattern Group, and specific Luma values within Groups. There are also dedi-
cated keys to move forward or backward within Groups or Patterns. Pattern switch-
ing is virtually instantaneous because patterns are not loaded from ROM or flash
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 user-defined Luma and Color val-
ues, select special features, and to navigate the On-Screen-Display (OSD) menus.
Detailed documentation for the IR remote control can be downloaded from
http://www.accupel.com.
OSD Menus
OSD (On-Screen-Display) menus provide access to advanced features including the
ability to specify user defined Luma and Color values, change output bit-depth,
blank individual R/G/B/Y/Cb/Cr output channels, modify color-encoding, set power-
up default modes, configure the USB interface, and more options.
USB Control Interface
The USB Control Interface provides full operation of all DVG-5000 functions, includ-
ing direct selection of every pattern. Detailed documentation for the USB Interface
can be downloaded from http://www.accupel.com.

Each time power is applied to the DVG-5000 the PLUGE, Gray Scale, and Gray Field
LEDs will illuminate in sequence for about 4 seconds as the generator is initialized.
The inactive Format LEDs blink once when any IR remote control command is
received. A rapidly blinking LED indicates that an IR remote control numeric key is
expected next (e.g. after Pat# key for direct selection by % value). Any slowly
blinking LED indicates that a special feature mode is active (e.g. Slow Edges).

Pattern Information
Each time a pattern is changed the name of the pattern, which includes important
signal identification information, is displayed on-screen for a short duration. The
duration can be selected in the OSD Misc menu (approximately 0.25, 0.5, 1.0, 1.5,
or 2.0 seconds), and the duration can be saved as a power-up default value. Press
the Info button on the remote control to display the pattern information continu-
ously. Press the Info button again to resume the default display period.
CIE xyY values are shown on the Info line for windows and fields in the Color75 and
Color100 pattern groups. The CIE x,y and Y (luminance relative to an equal ampli-
tude gray color) values are defined by the Color Gamut of applicable HD or SD
standards, and can be used as target values to adjust a Color Management System
(CMS). It can be advantageous to calibrate a display to have selectable Color Gam-
uts for the same signal format, therefore the target Color Gamut for HD, SD 60 Hz,
and SD 50 Hz signals can be changed in the Misc menu. The Color Gamut selection
changes only the CIE xyY target values for the display, and does not affect the gen-
erator’s output signals.
OSD Menu System
The OSD Menu is produced in all digital output signal formats. The OSD Menu pro-
vides additional features such as:
•user-defined luma values and colors
•selectable RGB and YCbCr individual channel blanking (set to the black
level)
•advanced signal parameters (YCbCr color-encoding, 59.94/60 Hz frame
rates HDMI 10-bit and 12-bit Deep Color YCbCr 4:2:2 bit-depth and filter-
ing, Digital Sync Polarity)
•AVI InfoFrame parameters
•USB port control
•user-defined generator power-up default modes.
OSD Menu Navigation
Press the Menu button to display the OSD window, which is organized into three
columns. The left column of the OSD window currently lists seven menus—User
Level, Output, Sync, Misc, USB Port, Defaults, and AVI InfoFrame. Use the cursor
keys to highlight (green text) the desired menu, and then move into the middle col-
umn and highlight a menu item. The current status of each highlighted menu item
is shown in the right column. To change a setting move into the right column and
highlight one of the alternative settings that will be listed in that column. In most
cases it is not necessary to press the Enter key unless “Enter” appears in the right
column. In that case highlight “Enter” and press the remote control Enter key to
proceed.
12
On Screen Display (OSD)
Press the Menu button to turn the OSD menu on or
off. The highlighted (green text) cursor position in the
OSD menu is maintained when the menu is turned on
or off, so it is easy to turn the menu off when making
measurements or adjusting a calibration setting, and
then turn it back on again to make additional changes
to the same menu item.
Menu items that are not applicable to the current sig-
nal output type are dimmed and not accessible in the
menu. For instance, the YCbCr 4:2:2 Filter selection
menu item is not accessible unless the YCbCr 4:2:2
output mode is active.

0%-100% Gray Scale patterns. The Gray Scale LED will blink
slowly when the Low-GS or High-GS mode is enabled.
Mute This button produces a 0% black field. Press any button on the
remote control (including Mute) to restore the previous pattern.
Func Mute Press this button combination to alternate between HDMI and
DVI output modes if the OSD menu is not visible on some dis-
plays in the HDMI (default) output mode. This is normally only
the case on older video displays and computer monitors with
DVI only inputs that may be incompatible with HDMI protocols.
*100%-109% patterns are not available for RGB-PC signals because the maxi-
mum signal amplitude is 100% (digital 255 or 1023) for RGB PC signals.

Digital RGB/YCbCr Video Output
The HDMI connector provides RGB-Video, RGB-PC, YCbCr 4:4:4, or YCbCr 4:2:2
digital video signals. A passive HDMI to DVI output adapter or cable can be used to
connect to DVI inputs.
USB Input/Output Port
USB input/output. Use a Type A to Type A USB cable to connect the DVG-5000 to a
computer. Requires a DVG-5000 USB driver that can be downloaded from
http://www.accupel.com. (See the DVG-5000 USB Interface manual for details.)
+6V DC Regulated Input
Use the supplied DVG-5000 6V DC regulated power module only. Use of any other
power module invalidates the DVG-5000 warranty.

Color 75 Group
•75% Tri-split Color Bars – Check or adjust Color Saturation and Hue
controls by matching color bars while individually viewing each primary
color. (Use display controls to enable single primary colors, or view
through color filters.) Similar to SMPTE Color Bars, but offset and split for
easier use.
•75% Color Bars - Standard Color Bars at 75% levels.
•75% Color Windows – Primary, complementary, and gray windows pro-
vide accurate CIE color measurements by using the same screen area.
•75% Color Fields – Primary, complementary, and gray fields to measure
color field uniformity and chroma noise.
Color 100 Group
•100% Tri-split Color Bars – Check or adjust Color Saturation & Hue at
100% levels.
•100% Color Bars - Standard Color Bars at 100% levels.
•100% Color Windows - Primary, complementary, and gray windows pro-
vide accurate CIE color measurements by using the same screen area.
•100% Color Fields - Primary, complementary, and gray fields to measure
color field uniformity and chroma noise.
•User Color - Replaces 75% and 100% gray colors in both Color 75 and
Color 100 group patterns to provide easy comparison with other standard
colors.
Special Group
•Low APL Overscan - Measure/adjust overscan and corner/edge geome-
try, convergence, and focus. 0% luma background. 0%-7% horizontal and
vertical overscan lines in 1% intervals.
•High APL Overscan - Measure/adjust overscan and corner/edge geome-
try, convergence, and focus. 100% luma background. 0%-7% horizontal
and vertical overscan lines in 1% intervals.
•Cross-Hatch - Low APL pattern to measure geometry & convergence.
•Inverse Cross-Hatch - High APL pattern for geometry & convergence.
•Dual Needle Pulse – Adjust CRT Contrast. Measure short-term CRT high-
voltage stability and check for CRT Scan Velocity Modulation.
•Color Pixel Multiburst - Adjust chroma-luma delay and signal peaking
(Sharpness/Detail Controls). Red/cyan, black/white, and blue/yellow
bursts.
1080p - 5,4,3,2,1 pixel bursts - 14.85, 18.56, 24.75, 37.13, 74.25 MHz
