INTRODUCTION
Thank you for purchasing the Gefen TV Signal Generator.
The Gefen TV Signal Generator offers a long list of advanced features. It provides
still and moving test patterns in SD and HD formats. It will also output audio
tone in 2, 4, 6, and 8 channel over HDMI. There’s also a test that will output
an HDCP encrypted signal to test HDCP-compliancy. Best of all, the Gefen TV
Signal Generator is portable, cost effective, and is a useful tool that allows video
professionals to calibrate and test video equipment and displays.

How to connect the Gefen TV Signal Generator
• Connect the HDMI OUT of the Gefen Signal Generator to the HDMI of
you HDMI display or device
• Plug the 5V power supply into the Gefen TV Signal Generator
• Turn on the display rst.
• Turn on the Gefen TV Signal Generator second
You should now be receiving a default signal from the Gefen TV Signal
Generator.
You may need to press the OVERSCAN button if the signal from the Gefen TV
Signal Generator does not ll 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 port #. 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
7.
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 8).
Checking stereo or multi-channel audio capability
• Connect the HDMI OUT to the HDMI IN of your A/V receiver (if
applicable).
• Connect the HDMI OUT of the Gefen TV Signal Generator to the
HDMI IN of your A/V receiver.
• Connect the HDMI OUT from the A/V receiver to the HDMI IN of your
display.
• Set the Audio Output Selector to INT SINEWAVE.
• Use the Pattern Selector buttons to select P38 AUDIO and follow the
on-screen directions.
The audio test is capable of verifying 2, 4, 6 and 8 discrete channel audio.

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 the Audio
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 veried through HDMI or DVI connections.
Automatic Testing
The Gefen TV Signal Generator has the capability to auto select specic
timings from the table provided on page 7.
Press the AUTO button to start auto mode. To stop the auto mode, press the
AUTO button again.
