1. OVERVIEW
The 7751TG2-HD Test Signal Generator modules provide a cost-effective method of generating 1.5 Gb/s
HDTV 4:2:2 and 4:4:4 test signals. The 7751TG2-HD is ideal for checking signal path integrity, or to
determine system performance over varying cable lengths. The 7751TG2-HD generates test signals in a
wide variety of HDTV video formats. In single link mode, the 7751TG2-HD outputs a SMPTE 292M 4:2:2
test signal on two outputs and a selected SMPTE 292M 4:2:2 black signal on the remaining two outputs. In
dual link mode, the 7751TG2-HD outputs a SMPTE 372M 4:4:4 test signal on two dual-link outputs.
The 7751TG2-HD provides an analog genlock input that allows you to synchronize the test signals to your
facility’s horizontal and vertical timing.
The 7751TG2-CF-HD version has the ability to generate both 270 Mb/s SD-SDI and 1.5 Gb/s HD-SDI test
signals and provides downloadable bitmaps for trouble slides or test slides. Users may store their own
designed bitmaps (trouble slides, test slides, or test signals) into a directory structure on the compact
flash. The 7751TG2-CF-HD comes with a 128MB compact flash. All sections of this manual apply to the
regular version as well as the 7751TG2-CF-HD unless otherwise noted.
Separate audio tones can be embedded into each channel of all four embedded audio groups. The user
can independently enable or disable embedding on any of the four audio groups. In dual link mode, the
selected audio groups will be embedded into each link. The 7751TG2-HD Audio Level range is
controllable from mute (silence), 0dBFS to -28 dBFS in increments of 2dBFS. The Audio level for the
7751TG2-CF-HD is fixed at -20 dB full scale.
Features:
•Wide variety of 1080i, 1035i, 1080p, 480p and 720p output formats
•Supports SMPTE 292M and SMPTE 372M Dual Link
•8 position DIP switch selects output format, single or dual link and genlock reference
•Card edge toggle switch selects test signal
•Selectable genlock input format – bi-level or tri-level sync, colour black
•16 embedded audio tones, selectable audio group assignment into all four groups
•4 output drivers
•On Screen display of test signal names
•On Screen setup menu
•Tally output upon loss of genlock
•Front panel LEDs indicate genlock presence, module fault and embedded audio signal presence on
the output
•Embedded SMPTE 334M Closed Caption Test signals
Additional features (7751TG2-CF-HD):
•Supports 525 and 625 line formats
•Compact flash for user created bitmaps (trouble slides, test slides, or test signals)

From this point forward, the 7751TG2-HD and the 7751TG2-CF-HD modules will be
referred to as the “7751TG2-HD”, unless the feature in question is applicable only
to one of the modules, in which case the specific model number will be referenced.

2. INSTALLATION
The 7751TG2-HD module comes with a companion rear plate that has 5 BNC connectors. For information
on mounting the rear plate and inserting the module into the frame see section 3 of the 7700FR chapter.
Figure 2-1: 7751TG2-HD Rear Panels
GENLOCK: Input BNC connector for analog genlock reference. The genlock signal may be a HD tri-
level sync, a standard definition colour black video or 0.3 V bi-level sync. DIP switch 6
enables the genlock reference, and the Genlock Setup On Screen menu is used to
configure the genlock type and to set up the timing of the output signal with respect to the
reference input. Table 5-2 provides a list of the valid reference signal types for the HD
output video format you have selected. Jumper J32 selects whether the reference input is
terminated or high impedance. (See section 6.3)

HD OUTPUT TG/LINK A: This pair of BNC connectors has serial component video outputs compatible
with the SMPTE 292M standard. The 7751TG2-CF-HD model supports 525 and 625 line
formats compatible with SMPTE 259M. DIP switches 1 to 5 select the video standard (refer
to Table 5-2). When the 7751TG2-HD is operating the 4:2:2 mode, these outputs contain
the test signal. When the 7751TG2-HD is operating the 4:4:4 mode, these outputs contain
the 4:2:2 channel (YCB(even)CR(even) or GB(even)R(even)) part of the SMPTE 372M test signal
known as Link A.
HD OUTPUT BLK/LINK B: This pair of BNC connectors has serial component video outputs compatible
with the SMPTE 292M standard. The 7751TG2-CF-HD model supports 525 and 625 line
formats compatible with SMPTE 259M. DIP switches 1 to 5 select the video standard. (See
Table 5-2) When the 7751TG2-HD is operating the 4:2:2 mode, these outputs contain a
black video signal. When the 7751TG2-HD is operating the 4:4:4 mode, these outputs
contain the Alpha channel (ACB(ODD)CR(odd) or AB(ODD)R(odd)) part of the SMPTE 372M test
signal known as Link B.
