Testing HDCP Interfaces
Model 701A video test generators may be equipped with an optional production (private) key for
testing High-bandwidth Digital Content Protection (HDCP) interfaces of DVI receivers that support
HDCP. For more information about HDCP, see http://www.digital-cp.com/.
To output HDCP-encyrpted video content:
1. Connect the DVI connector of the generator with the DVI connector of the device under test.
2. Choose a DVI video format supported by the device.
3. Press Test > HDCP > Start to output HDCP encrypted content.
The display on the generator indicates if the test passed or failed. If the test passed, the currently
selected pattern is displayed on the device under test. Noise is displayed if the HDCP authenti-
cation failed.
After the initial authentication of the connection is established, the generator displays the number
of authentication verficiation cycles until you stop the test.
During the test, if you reconnect the cable or restart the device under test, the test should restart
automatically.
4. To stop the test, press the Exit soft key or any gray key.
