Testing with source devices
With the Analyzer option, the generator can emulate an HDMI/DVI sink (display) in order to
test an HDMI source device’s EDID handling. With this capability, an HDMI/DVI source
device can be tested for its ability to handle an EDID received from virtually any
DDC-compatible display.
The analyzer emulates HDMI/DVI displays using a built-in, configurable EDID structure.
You can configure the analyzer to use an EDID structure obtained directly from a display
device, or from a EDID XML file stored in the generator’s file system.
Capturing and storing EDID from display device
Follow the procedure to capture and store an EDID structure from a display device
connected to the generator’s HDMI output (Tx) port.
To capture and store an EDID from a connected HDMI/DVI display device:
1. Establish a session with the generator using either HyperTerminal over a serial
connection or Telnet over an Ethernet LAN. See “ Establishing a terminal session with
the generator ” on page 31 or “ Establishing a Telnet session with the generator ” on page
34.
2. Connect the 882 HDMI output (Tx) port to the display device whose EDID you wish to
capture.
3. Activate the HDMI-H or HDMI-D 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 the HDMI-H or HDMI-D item by pressing the adjacent soft key. The
interface is activated and the port outputs the currently selected image and format.
c. Alternatively, to activate the interface through the command line interface, enter the
following commands:
XVSI 3 (or 4) // Selects the HDMI-D (or HDMI-H) interface
ALLU // Applies the interface setting to the generator
