The Gefen TV Signal Generator
The Gefen TV Signal Generator is a hand-portable, cost-effective testing tool
that allows installers to locate and eliminate problems with HDTV Equipment and
Displays, as well as calibrate equipment on-the-spot.
How It Works
Simply connect the HDMI output port of the Gefen TV Signal Generator to your
HDTV display. Power-cycle all equipment. Activate the On-Screen Display (OSD)
Menu via the remote control and select the tests that you would like to perform.
The easy-to-use on-screen menu system will guide you through the options and
features. You can feed digital or analog audio into the Signal Generator rear
panel in order to hear music while testing displays rather than hearing the default
high-pitched audio test tone.

How to connect the Gefen TV Signal Generator
1. Connect the HDMI OUT of the Gefen Signal Generator to the HDMI of your
HDMI display or device.
2. Plug the 5V power supply into the Gefen TV Signal Generator.
3. Turn on the display first.
4. Turn on the Gefen TV Signal Generator second.
You may need to press the OVERSCAN button if the signal from the Gefen TV
Signal Generator does not fill the entire screen.
If you are not receiving a picture, check your power supply. Make sure the Gefen
TV Signal Generator is plugged in and that the unit is turned on. If your display
has more than one HDMI port, make sure that your display is set up to receive
signals from that input. If you’re testing HDMI, make sure that the Output Signal
Selector is set to HDMI.
If you are still unable to receive a picture, it is possible that the current output
timing is not supported by your monitor. The current timing (resolution and
refresh rate) are displayed in the LCD window on the unit. Use the Timing
Selector UP or DOWN buttons to select a different timing. See chart on page 8.
Once you have established a timing that is accepted by your display, you can
select from a wide array of video test patterns by using the Pattern Selector UP
or DOWN buttons (see table beginning on page 9).
Checking stereo or multi-channel audio capability
1. Connect the HDMI OUT to the HDMI IN of your A/V receiver (if applicable).
2. Connect the HDMI OUT of the Gefen TV Signal Generator to the HDMI IN of
your A/V receiver.
3. Connect the HDMI OUT from theA/V receiver to the HDMI IN of your display.
4. Set the Audio Output Selector to INT SINEWAVE. (If you are using the
optional digital optical or analog stereo audio inputs, please select those
instead.)
5. Use the Pattern Selector buttons to select P38 AUDIO and follow the
onscreen directions.
The audio test is capable of verifying 2, 4, 6 and 8 discrete channel audio.
CONNECTING AND OPERATING THE SIGNAL GENERATOR

CONNECTING AND OPERATING THE SIGNAL GENERATOR
External Audio Inputs
In addition to using the internal sinewave for checking audio, the Gefen TV
Signal Generator allows you to use your own audio source and accepts both
analog and digital audio signals. For digital audio connections, connect an optical
cable from your audio source to the OPTICAL input on the back of the unit and
select EXT OPT by pressing the Audio Selector button. For analog connections,
connect a stereo RCA cable to your audio source and plug the other end into the
Analog Input jacks and select EXT L/R by pressing theAudio Selector button. To
prevent a reversed stereo image, make sure that the left and right channels are
connected properly.
Testing DVI
You can test DVI devices by setting the Output Signal Selector to DVI. This
button will toggle between HDMI and DVI color space. Simply connect the HDMI
OUT from the Gefen TV Signal Generator to the DVI IN of the device you wish to
test.
Color Space
You can switch color spaces by pressing the Color Space Selector button.
Pressing this button will cycle through RGB, YUV2 and YUV4 color spaces.
HDMI supports all color spaces but DVI only supports YUV2.
HDCP compliance
To check HDCP compliance, select a timing that is accepted by your display and
use the Pattern Selector buttons to select P39 HDCP-Produce from the list of
patterns.
You can also check audio in this mode by setting the Audio Output Selector to
INT SINEWAVE.
HDCP testing can only be verified through HDMI or DVI connections.
Automatic Testing
The Gefen TV Signal Generator has the capability to auto select specific timings
from the table provided on page 8.
Press the AUTO button to start auto mode. To stop the auto mode, press the
AUTO button again.
