Introduction
AccuPel HDG-4000 Analog/Digital Video Calibration Generators are professional test equipment exclusively
for commercial or industrial calibration and testing of video monitors, projectors, and signal processors.
Versatile Signal Outputs
The HDG-4000 produces YPbPr and RGB analog component video compliant with EIA/CEA-770.2 (480i/p),
EBU-N10 (480i/576i), and EIA/CEA-770.3 (1080i/p & 720p) standards. YPbPr and RGB analog component
video is also compliant with SMPTE-274M (1080i/p), and SMPTE-296M (720p) standards, except that sync
is present on Y or G signals only in accordance with EIA/CEA consumer standards. The HDG-4000 also
produces Y/C (S-video) and CVBS (Composite) video compliant with NTSC and PAL standards.
The YPbPrs and RGBs analog output modes are intended for compatibility with professional transcoders
and scalers that retain 7.5-IRE black-level setup when converting standard-definition component video with
7.5 IRE setup. The YPbPrs mode is also compatible with DVD players that produce Panasonic MII
component video signals (480i) with black-level setup.
Digital video output signals are compliant with EIA/CEA-861-B (480i/480p/1080i/720p/1080p). Digital RGB
signals are selectable for compatibility with RGB-PC levels or RGB-Video levels. Digital YCbCr 4:2:2 and
YCbCr 4:4:4 signals are provided for compatibility with HDMI inputs.
22 Video Signal Formats
The HDG-4000 produces up to 22 video signal formats. The HDG-4000 L1 (Level 1) produces 16 video
formats including 480i, 480p, 720p59.94, 720p60, 1080i59.94, 1080i60, 1080p59.94, 1080p60,
1080p23.976, 1080p24. 1080p23.976sf, 1080p24sf, 1080p29.97, 1080p30, 1080p47.95, and 1080p48. The
HDG-4000 L2 (Level 2) adds six additional 50 Hz formats including 576i, 576p, 720p50, 1080i50, 1080p25,
and 1080p50.
Digital YCbCr 4:4:4/4:2:2 Signals & Digital RGB Signals With Video and PC Levels
The Digital output produces digital RGB signals and digital YCbCr 4:4:4/4:2:2 signals for DVI or HDMI
inputs. The 8-bit digital RGB signals can be selected to comply with RGB-PC or RGB-Video signal levels.
RGB-PC digital levels are 0-255 for black (0%) to reference white (100%), and therefore below-black or
above reference white RGB-PC levels are not permitted. RGB-Video digital levels are 16-235 for black (0%)
to reference white (100%), and therefore below-black and above reference white (to 109%) RGB-Video
levels are available for PLUGE patterns and dynamic range calibration.
Versatile Sync Options
High-definition (1080i/p & 720p) analog signals have selectable Tri-Level Sync per EIA/CEA-770.3 (sync on
Y or G only) or Bi-Level Sync for compatibility with older video upconverters that lacked Tri-Level sync
generation. Standard-definition (480i/p, 576i/p) signals have Bi-Level sync (on Y or G only per EIA/CEA-
770.2).
Embedded Bi-Level and Tri-Level sync-on-green/sync-on-Y can be disabled for RGB signals. Separate H, V
sync is available with positive or negative polarity for RGB signals, or a special scope trigger output can be
selected to trigger oscilloscopes or other test equipment when using YPbPr or digital video output signals.

10-Bit Analog Video DACs & Separate Sync Generation
The YPbPr and RGB analog component video signals, and the Y component of Y/C and CVBS signals, are
generated by 10-bit Digital to Analog Converters from internal 10-bit 4:4:4 YPbPr and RGB digital signals.
The analog embedded sync signals are produced without using any of the 10-bit video DAC dynamic range.
Other generators may trade-off 30% of the video signal resolution to generate sync signals, or use 8-bit
Digital to Analog Converters with less resolution or linearity.
Direct-Drive Digital (D3)Pattern Generation
All video patterns & sync signal timing is generated using three low-noise, high-stability, crystal oscillator
clocks. There are separate oscillators for 480i/p and 576i/p, for 59.94 Hz based high-definition (HD) formats,
and for 50.00/60.00 Hz based HD formats, per applicable SMPTE and EIA/CEA standards. A proprietary
AccuPel 30-bit digital RGB/YPbPr pattern generation IC directly drives precision 10-bit resolution Digital-to-
Analog Converters for analog component video output. Completely separate 24-bit RGB-Video, RGB-PC,
and YCbCr digital values directly drive the digital video output transmitter without any digital truncation or
conversion errors. No clock synthesizers, format converters, color-space converters, or frame buffers are
used to ensure maximum signal accuracy.
Professional Quality Analog Signal Interfaces
True 75-ohm BNC signal outputs provide the highest-quality analog YPbPr or RGB interface to front
projectors and other displays over long cable runs. All analog YPbPr or RGB signals are simultaneously
available through the DVI-I output connector to drive a separate monitor or test system. All video and HV
sync signals are 75-ohm reverse terminated for optimum pulse fidelity.
Infrared Remote Control
The 41-key IR remote control provides dedicated buttons to directly select each Output mode, Format mode,
Pattern Group, and individual patterns within the current group. There are also dedicated rocker buttons to
move forward or backward through Groups or Patterns. A user-defined Pattern List provides the easiest way
to switch back and forth between several patterns as you work. A single button push will store or delete up
to 6 patterns from a Pattern List, and then move forward or backward through the user-defined Pattern List.
The IR remote control also provides dedicated buttons to enter User-defined Luma and Color values, select
special features, and to navigate the On-Screen-Display (OSD) menus.
Detailed documentation for the IR remote control can be downloaded from the AccuPel website at
www.accupel.com.
OSD Menus
OSD (On-Screen-Display) menus provide access to many advanced features including the ability to specify
user defined Luma and Color values, choose Y/C and CVBS chroma bandwidths, enable/disable output
channels, select sync options, set power up default modes, and configure the serial interface ports.
USB & RS-232C Serial Control Interfaces
The USB and RS-232 Serial Control Interfaces provide full operation of all HDG-4000 functions, including
direct selection of each pattern. Complete documentation for the Serial Interfaces can be downloaded from
the AccuPel website www.accupel.com.

Front Panel Controls
LED Indicators
Each time power is applied to the HDG-4000 the PLUGE, Gray Scale, and Gray
Field LEDs will illuminate in sequence for about 4 seconds as the generator is
initialized.
All unused Format LEDs blink once when an IR remote control command is
received. All unused Format LEDs blink rapidly 4-times if a currently invalid
command is received. Any slowly blinking LED indicates that a Special Feature
mode (e.g. Slow Edge) is active.
1 Output Selector
The Output button selects the type of analog and digital video signals produced
by the HDG-4000. The YPbPr and RGB analog video signals comply with the
standard-definition (SD) EIA/CEA 770.2 and EBU-N10 standards, and the
EIA/CEA 770.3 high-definition (HD) standards. HD signals also comply with
SMPTE 274M and SMPTE 296M levels and color encoding, but the tri-level sync
is on the Y/G signal only (per the 770.3 consumer standard), unlike the SMPTE
standards that have sync on all three component signals.
The YPbPrs and RGBs signals mimic the behavior of professional upconverters
and scalers that convert standard-definition video with black-level setup to 1080i
or 720p video without removing the setup. The YPbPrs (480i) mode also complies
with the professional Panasonic MII standard, and early DVD players that
included black-level setup on their 480i YPbPr output.
Y/C (S-video) and CVBS (Composite video) standards are only defined for
standard-definition interlaced signals. Therefore, the Y/C and CVBS output modes
produce 480i and 576i (HDG-4000 L2 only) format signals only. When the Y/C or
CVBS output is selected the signal format will automatically change to either 480i
or 576i (depending on whether the previous format was based on 60 Hz or 50 Hz
respectively). The previous format will be restored when the Output type is
changed again, which allows the Output button to cycle “through” the Y/C and
CVBS modes without having to reselect the original Format. Similarly, the Output
type must be changed from Y/C or CVBS before the Format can be changed to
anything other than 480i or 576i.
Digital signals are always available from the DVI-I connector. When the Y/C or
CVBS mode is selected the digital output signals are YCbCr 4:4:4.

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 six menus – User Level,
Output, Sync, Misc, Com Ports, and Defaults. Use the cursor keys to highlight the
desired menu, and then move into the middle column 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
then 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.
Press the Menu button to turn the OSD menu on or off.
The highlighted 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.
