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 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 7.
Press the AUTO button to start auto mode. To stop the auto mode, press the
AUTO button again.
