EDID emulation for physical layer testing of source devices
The 882C/E supports some of the physical layer tests called out in the HDMI CTS such as
eye measurements and TMDS rise and fall time measurements. These tests are
performed using commercially available oscillocopes recommended in the HDMI CTS. In
support of these tests, the Multi-Purpose Adaptor (TPA-MP-4R shown below) provides
EDID emulation, a hot plug source and AVcc power source.
While standard HDMI-to-HDMI cables connect the generator to the TPA-MP-4R device,
cables available as an option through Quantum Data are used to connect that device to
the source device under test. Two methods for testing EDID compliance with HDMI source
devices are shown below. One uses the Tektronix Test Instrument and the second uses
the Agilent Test Instrument.
