7750TG2-HD HDTV Test Signal Generator
Revision 1.2.3 7750TG2-HD-1
1. OVERVIEW
The 7750TG2-HD Test Signal Generator provides a cost-effective method of generating 1.5 Gb/s HDTV
4:2:2 and 4:4:4 test signals. The 7750TG2-HD is ideal for checking signal path integrity, or to determine
system performance over varying cable lengths. The 7750TG2-HD generates test signals in a wide
variety of SMPTE 292M video formats. In single link mode, the 7750TG2-HD outputs a 4:2:2 black signal
on two outputs and the selected 4:2:2 test signal on the remaining two outputs. In dual link mode, the
7750TG2-HD outputs a 4:4:4 test signal on two dual-link 4:4:4 outputs.
The 7750TG2-HD provides an analog genlock input that allows you to synchronize the test signals to your
plant horizontal and vertical timing.
Separate audio tones can be embedded into each channel of one of the four embedded audio groups. The
user can select which of the audio groups the tones will be embedded into. In dual link mode, the selected
audio groups will be embedded into each link. The Audio level is fixed at -20 dB full scale.
Features:
•Wide variety of 1080i, 1035I, 1080p, 480p and 720p output formats
•8 position DIP switch selects output format, single or dual link and genlock reference
•Card edge toggle switch selects test signal
•Selectable gen lock input format – bi-level or tri-level sync, colour black
•4 embedded audio tones, selectable audio group assignment
•4 output drivers
•On screen display of test signal names
•On screen setup menu
•Tally output upon loss of gen lock
•Front panel LEDs indicate gen lock presence, module fault and audio signal presence on the output

7750TG2-HD-2 Revision 1.2.3
2. INSTALLATION
The 7750TG2-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 the 7700FR chapter section 3.
Figure 2: 7750TG2-HD Rear Panel
GEN LOCK Input BNC connector for analog Gen Lock reference. The genlock signal may be a HD tri-
level sync or a standard definition colour black video or 0.3 V bi-level sync. DIP switch 6
enables the Gen-Lock reference and the Gen Lock 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 3 gives a list of the valid reference signal types for the HD output video format you
have selected. Jumper J2 on the A7700REF sub-module selects whether the reference input
is terminated or high impedance. (See section 6.3)
HD OUTPUT LINK A This pair of BNC connectors has with serial component video outputs compatible
with the SMPTE 292M standard. DIP switches 1 to 5 select the video standard. (See Table 3)
When the 7750TG2-HD is operating the 4:2:2 mode these outputs contain the test signal.
When the 7750TG2-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 test signal.

HD OUTPUT LINK B This pair of BNC connectors has with serial component video outputs compatible
with the SMPTE 292M standard. DIP switches 1 to 5 select the video standard. (See Table 3)
When the 7750TG2-HD is operating the 4:2:2 mode these outputs contain a black video signal.
When the 7750TG2-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 test signal.
The test signal output is selected using the toggle switch located on the card edge. The Audio
Setup On screen menu is used to configure any embedded audio that will be present on the
outputs.

4. STATUS LEDS
4.1. MODULE STATUS LEDS
The location of the status LEDs is shown in Figure 7.
MODULE OK This Green LED will be On when the module is operating properly.
LOCAL FAULT This Red LED will blink on and off if the microprocessor is not running. The LED will
be on solid when there is a fault in the module power supply.
SIGNAL PRESENT: This Green LED will be On when there is a valid genlock signal present at the
module genlock input.
!This LED does not necessarily indicate that the genlock signal is the correct
frame rate for the selected output video format. For example, if a 59.94 Hz signal
is required for the selected output video format, but a 60 Hz signal is present at
the genlock input, the SIGNAL PRESENT LED will be On. In this case the output
video will NOT be properly referenced but will constantly try to resync to the
genlock frame reference.
AUDIO: This Green LED will be On when there is audio embedded into the outputs.

A three position, return to center toggle switch is used to select the various test signal patterns and is also
used in conjunction with a momentary pushbutton to operate the On screen Setup menu.
5.1. SELECTING THE OUTPUT VIDEO FORMAT
DIP switches 1 to 5 are used to select the output video format of the 7750TG2-HD. The On position is
down, or closest to the printed circuit board. Table 3 shows the settings of the DIP switches for selecting
the video output formats, and the types of genlock signals that can be used with each.
!For 480p/60 or 480p/59.94 format over SMPTE 292M interface use 1080i/60 or
1080i/59.94 respectively. Extra test signals for 480p are available only in these
video formats.
