ANALYZER OPTION
Overview
Use the DVI and HDMI analyzer option to test HDMI 1.3
deep color source products, such as set-top boxes, DVDs
as well as repeaters and cables. Source product manu-
facturers will find this option invaluable for verifying signal
quality, timing, color encoding, and E-EDID/E-DDC/HPD-
related behavior.
The analyzer option adds a digital video receiver to the
base instrument. This receiver emulates a sink device
(display), while the generator output emulates a source
(host) device. The receiver presents an on-the-fly repro-
grammable E-EDID to the source, and analyzes incoming
video for data errors and timing anomalies. The receiver
can analyze video from the instrument itself or from an
external source. Results can be displayed on the instru-
ment’s front panel or issued as formatted reports.
The HDMI and DVI analyzer option passes through the
incoming digital signal to the HDMI Tx interfaces, which can
be connected to a HDMI display for monitoring incoming
content. The displayed image rendered identically as the
source on a pixel per pixel basis. The analyzer also routes
incoming audio to a SPDIF output, which can be connected
to an external digital speaker or audio analyzer.
Signal quality can be measured without meticulous
inspection of a display screen. The analyzer accepts stan-
dard QDI-BCM pseudo-random noise test patterns, which
allow overall signal quality to be measured and expressed
in simple objective terms. In cases where the analyzer is
connected to a video source that does not support the
rendering of pseudo-random noise data, a pixel error
measurement technique can be alternately used, which
counts flickering pixels in still-frame test images. Detailed
pixel-by-pixel analysis is also supported for checking color
encoding, scaling, and masking in test images.
Timing can be measured, independent of video content.
The signal analyzer manager can be used to check sever-
al timings and obtain HTML report.
The analyzer option is also excellent for finding problems
with repeaters, cables, cable extenders, and distribution
systems. Everything needed to test transmission systems
from end-to-end, using pseudo-random noise or test
images, is now available in a single instrument.
The analyzer optionally supports CEC compliance testing
with the Test Management Environment (TME). The TME
application is used for testing CEC compliance in the
HDMI Authorized Test Centers.
The analyzer optionally supports HDCP compliance testing
enabling developers of HDMI products to perform fast,
comprehensive HDCP compliance test. on sources, sinks
or repeaters, in accordance with the HDCP compliance
test specification.
Signal Analyzer Features
> EEPROM Emulator emulates an EEPROM (up to 8
blocks) with rapid on-the-fly re-programmable
E-EDID for testing how source devices respond
to different sink devices.
> EDID Editor. Supports acquisition, editing and
emulation of EDIDs including CEA extension block.
> Hot-Plug Generator generates hot-plug events
in concert with E-EDID changes.
> Timing Analyzer measures timing of external
video signal.
