Running an HDMI HDCP self-test

Chapter 13 Testing HDCP on HDMI
432
An HDCP self-test checks that HDCP authentication is working properly between the
transmitter and receiver on the analyzer. This test can also be used to confirm that a cable
is not interfering with HDCP authentication, and that the DDC clock and DDC data pins
(used by the I2C bus) are working correctly.
To run an HDCP self-test:
1. Connect the HDMI cable between the HDMI IN and HDMI OUT connectors on the 882.
2. Activate the HDMI-H interface on the output port as follows:
a. Press the Interface key. A listing of signal interfaces appears on the 882's display
as shown below.
VGA
*
HDMI-D
HDMI-H
b. Choose HDMI-H item by pressing the adjacent soft key. The interface is activated,
and the port outputs the currently selected image and format.
Alternatively, to activate the interface through the command line interface, enter the
following commands:
XVSI 3 // Selects the HDMI-H interface
ALLU // Applies the interface setting to the 882
3. Enter the following command to initiate and run the test with any image displayed. A
zero is returned if the HDCP test is successful.
HDCP? (OUT1:HDCP?, OUT2:HDCP?)
You can also specify a number of frames to run the test for. For example to run the test
for 2000 frames you would enter:
HDCP? (OUT1:HDCP?, OUT2:HDCP?)
