The HDG-820/821 series by Link Electronics is a
series of broadcast High Definition Pattern
Generators, providing the user with high quality, low
cost system to produce HD Test Patterns. The
HDG-820/821 is a self contained product for
standard 19 inch rack mounting.
The HDG-820/821 is a high defintion video test
pattern generator in a stand-alone one rack (RU)
chassis. The unit has two serial digital outputs at
1.485GB/s and YUV-RGB analog outputs. The
digital and analog outputs are simultaneous on the
rear panel, and contain the same test pattern. The
user may embed internal audio tones on the digital
video output, if desired.
There are two audio groups supported, which allow
for eight channels. The channels can be enabled on
an individual basis. The internal tones generated are
adjustable from 400Hz to 10KHz, 0 to -30dBFS.
There are also two BNC connectors for AES output,
which will allow four channels of audio for
monitoring. Serial control will allow changes to be
made via a PC, (the serial control is a development
for a later release). There are a total of thirty test
signals available, including SMPTE, EIA and Full
Field Bars.
The Link Electronics product design, performance
and reliability are reflected in the New-Generation of
Link Electronics products. A pair of lighted push
buttons and an optical rotary encoder change and
select various menus. User friendly operation is a
key concept of the HDG-820/821.
The 20X2 Vacuum Fluorescent Dispaly shows data
for operational functions. All user controls are made
from the front panel. All internal adjustments are
made by potentiometers for precise and accurate
settings. The user may choose to have all of the
selections saved for power up defaults.
The HDG-820/821 multi-format generator can be
used where various HD signals are required. Tri-
level-sync has its own separate output and is on all
analog component outputs, RGB or YUV.
The HDG-821 is a gen-lock unit with a pair of looping
BNC connectors on the rear panel. The gen-lock
version provides adjustment of H & V Timing. The
HDG-820 is a non gen-lock unit.
