492 Chapter 15 Auxiliary Channel Analyzer
Monitoring the HDMI auxiliary channels
This subsection provides procedures on operating the ACA for monitoring the HDMI
auxiliary channels such as the HDCP and EDID transactions over the DDC or the CEC
transactions over the CEC bus. The procedures are the same regardless of whether you
run the ACA from the web server or from your PC.
To set up the generator for monitoring the DDC on HDMI:
1. Connect the generator to the HDMI display device or source device under test by doing
one of the following:
a. Connect an HDMI-to-HDMI cable between the HDMI display device or source
device under test and either of the HDMI OUT connectors on the generator.
b. If you are using the analyzer, connect an HDMI-to-HDMI cable between the HDMI
display device or source device under test and the HDMI IN connector on the
generator.
2. Activate the HDMI-H interface on the output port:
a. Press the Interface key to access the list of interfaces. A listing of signal interfaces
appears on the generator’s display as shown below.
b. Choose either the 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 select the interface through the command line, enter the following
commands:
XVSI 4 // Selects the HDMI-H interface
ALLU // Applies the interface setting to the generator
To monitor the CEC bus (channel):
1. Set up the generator/analyzer for HDMI in accordance with the instructions above.
