W2641A Datasheet, PDF (2/8 Pages) Agilent(Hewlett-Packard) – DisplayPort Test Point Access Adapter

Emerging standards for
consumer electronic devices and
entertainment equipment provide
for higher screen resolutions
than ever before, which meets
the market need for the highest
computer monitor viewing
quality possible. High screen
resolutions necessitate higher
link rates which place new
demands on the source, sink
and media such as cable or PC
boards. This electrical signal
environment makes measurement
of physical layer parameters even
more important and at the same
time, more difficult. The Agilent
Techologies W2641A DisplayPort
test point access adapter
provides unrivaled convenience
and performance.
DisplayPort standard
The evolution of the DisplayPort standard, sponsored by VESA¹, was driven by
demand for higher-resolution and less-expensive computer displays. Computer
industry insiders have long believed that the industry would ultimately shift to
all digital flat-panel displays, and DisplayPort is the digital transport interface
standard that finally promises to supplant the popular VGA CRT monitor. The
low-profile DisplayPort connector is ideal for crowded back panels, motherboard
designs able to drive multiple monitors, and portable equipment that offers
uncompromised viewing. The DisplayPort connector has been designed to support
the high DisplayPort bit rates now and in the future. It is likely that DisplayPort
will become the primary video interface for desktop and laptop personal
computers, and it may ultimately be used in consumer electronics equipment
such as DVD players.
The DisplayPort standard covers a wide range of screen resolutions and physical
configurations. It outlines tests for the high-speed digital signals for source
and sink testing, low-frequency control path (the AUX channel), link -layer and
protocol verification such as HDCP (high bandwidth content protection) and
media evaluation.
