1.0 INTRODUCTION
The 1T-TG-620 HDMI Test Generator provides a means to verify the correct
operation of HDMI equipment such as monitors and projectors. Any device with
an HDMI type input (plus PC or DVI-D displays with appropriate cable adaptors)
can be tested using several different types of test signals. A provision has been
made to embed either a 1Khz internally generated audio signal or an externally
generated audio signal in the digital bitstream so that operation of the audio
portion of the HDMI signal can be verified and, in addition, HDCP (High Definition
Content Protection) functionality can also be tested thereby insuring that all
video, audio and security components of the HDMI display device are functioning
properly.
Our professional video conversion products have been serving the industry for
over twenty years. TV One offers a full line of high quality Seamless Switchers,
Video Scalers, Up/Down/Cross Converters, Analog-Digital Converters (SD/HD-
SDI, HDMI, DVI), Format Converters, Standards Converters, TBC/Frame
Synchronizers, Matrix Routing Switchers, Signal Distribution Amplifiers and Cat.5
Transmission Systems.

1.3 Getting the Best Results
There are many factors affecting the quality of results when dealing with HDMI
type signals. Some basic precautions will ensure the best possible performance
from your 1T-TG-620 HDMI Test Generator.
Output display device –The quality of the output signal will depend largely
upon the type and quality of the HDMI display device used. For instance,
some video projectors just look better than others.
Distance between the Test Generator and the display –This plays a major
role in the final result. Long distances are possible, but special measures
should be taken in order to avoid cable losses. These include using high
quality cables. Line amplifiers may also be necessary for the longest runs.
Input/Output connection cables –Low quality cables are susceptible to
interference. They degrade signal quality due to poor matching and can
cause elevated noise levels. Cables should be of the best quality.
Interference from nearby electrical devices –These can have an adverse
effect on signal quality. For example, an older computer monitor often emits
very high electromagnetic fields that can interfere with the performance of
video equipment in its proximity.

3.0 CHECKING PACKAGE CONTENTS
Before attempting to use this unit, please check the packaging and make certain
the following items are contained in the shipping carton:
1x 1T-TG-620 HDMI Test Generator
1x 100~240VAC to 5VDC Power Adapter
1x Instruction Manual
1x Infrared Remote Control
Note: Please retain the original packing material should the need ever arise to
return the unit. If you find any items are missing, contact your reseller or TV One
immediately. Have the Model Number, Serial Number and Invoice available for
reference when you call.
4.0 CONNECTING THE HARDWARE
Connect the HDMI Video Device’s HDMI input to the Output of the 1T-TG-620
Test Generator and connect an External Audio signal (if desired) to the
Generator’s S/PDIF Optical connector. The drawings below show the locations
of the front panel controls, input, output and power connector.
1T-TG-620 HDMI Test Generator
You can connect any HDMI compliant device’s input to the HDMI output. Make
certain that the HDMI cable is securely plugged into the destination device as
well as the HDMI Test Generator. Always use a high quality cable, as short a
length as possible, for best results.
4.1 Connecting Power to the 1T-TG-620
The unit is shipped with a Power Adapter to convert 100~240VAC@50-60Hz to
5VDC. Connect the DC Output Cable from the Power Adapter to the back of the
unit and then plug the Power Adapter into an AC Receptacle. The 1T-TG-620
HDMI Test Generator will begin to function as soon as it receives power. There is
no power switch.

5.0 OPERATING THE 1T-TG-620 HDMI TEST GENERATOR
The 1T-TG-620 HDMI Test Generator can be operated directly via the front panel
controls or via the included Infrared Remote Control. An On Screen Display
(OSD) provides a menu that allows you to select the test signal or function
desired using the front panel buttons. (Operation via the Remote Control will be
described later.)

7 Up Arrow moves OSD cursor towards the top of the display.
8 Pressing the Menu and Down Arrow buttons at the same time will
return the 1T-TG-620 to the Factory Default setting.
* The Menu button is also the Enter Button. When you have reached the
pattern or adjustment you wish to utilize, pressing the Menu button allows
selection of the desired function or pattern and allows you to “Drill Down” into
the sub menus.

5.1 Menu Structure
Press [MENU] to show OSD Main Menu.
5.1.1 Pattern
On the Main Menu, press the arrow buttons as required to position the cursor
over the word “Pattern” and then press [Menu] to enter the pattern mode. There
are 8 different pattern groups available and you simply move the cursor and
press [Menu] to enter a particular pattern group. Press the up or down arrow
buttons to select previous/next pattern and select “Exit” to move back to the main
menu. Pressing Exit from the main menu will remove the OSD from the video
output.
The various patterns are shown below for reference purposes.
Color Bars
The color bar patterns provide a good overall check on color performance. This
includes the checks of burst keying, sub-carrier regeneration, RGB amplifier
balance, chrominance/luminance delay and a color saturation check.
Note that when the output resolution is 1080i, the horizontal Color Bar patterns
are not supported.

Gray Scale
The Gray scale pattern is used to locate non-linearity in a video amplifier. Non-
linearity results in compression of the white level and a loss of high frequency
detail.
Purity Check
The available purity colors are White, Blue, Red, Magenta, Green, Cyan, Yellow
and Black. The red and green patterns are most frequently used for checking
color purity.
In a correctly adjusted monitor, each electron beam will strike only one set of
color dots or stripes on the screen. If the red pattern is selected only this color
should be visible; the presence of any other color is an indication that color purity
needs adjustment.
The green pattern provides a purity check for three in-line tubes. In addition the
pattern serves as a reference to locate any geometrical distortions in these
picture tubes. In the in-line tubes, the guns are in a horizontal position and the
green gun is located in the center.
Blue, as well as the complementary colors, are often used to check the color
performance.
The other patterns (mainly RED) are used to ensure that there is no interference
between the sound and chroma carrier. In addition to the primary and
complementary colors 100% white can be selected as well as black pattern with
color burst. Purity patterns are also used for measuring unwanted amplitude and
phase modulation of the sub-carrier, AM and PM noise as it occurs with VCRs.
