Save time
The DisplayPort Electrical Performance
Validation and Compliance software
saves you time by setting the
stage for automatic execution of
DisplayPort electrical tests. Part of
the difficulty of performing electrical
tests for DisplayPort is connecting
the oscilloscope to the target device,
configuring the instrument for
measurements, executing the test
procedures, defining the capabilities
of the device under test, and then
analyzing the measured results by
comparing them to limits published
in the specification. The DisplayPort
electrical test software does almost all
of this work for you. In addition, if you
discover a problem with your device,
debug tools are available to aid in root-
cause analysis.
The DisplayPort software offers the
electrical tests for the source as
well as important tests for cable and
calibration for receiver tolerance
testing. The software automatically
configures the oscilloscope for each
test, and it provides an informative
results report that includes margin
analysis indicating how close your
product is to passing or failing that
specification. Clock recovery of each
lane is accomplished according to the
standard by the oscilloscope using
proprietary software techniques.
See Table 1 for a complete list of
the measurements made by the
DisplayPort electrical test software.
Easy test definition
The DisplayPort Electrical Performance
Validation and Compliance software
extends the ease-of-use advantages of
Agilent’s Infiniium Series oscilloscopes
to testing DisplayPort designs. The
Agilent automated test engine walks
you quickly through the steps required
to define the device under test, to
select the tests, set up the tests,
perform the tests, and view the test
results. You can pick high-level test
parameters to suit your test process
objectives, and then you can proceed
to select a category of tests all at
once, or specify individual tests. The
user interface is oriented to minimize
reconnections, which saves you
time and minimizes potential for
operator error. You can save tests
and configurations as project files
and recall them later for quick testing
and review of previous test results.
Straightforward menus let you perform
tests with a minimum of mouse clicks.
Further test process control is also
provided through the automation
tab of graphical user interface. This
tab allows the user to tailor scripts
to control external equipment such
as power supplies and temperature
control units, or to provide a different
test flow.
DisplayPort compliance software helps you do the right job faster
Features
The DisplayPort electrical test software
is a full-featured package to simplify
the validation process of DisplayPort
designs:
• Full Physical Layer Testing High
speed Lanes and AUX channel
• Full physical layer testing of AUX
channels
• Support of multiple CTS versions
• Test Status tracking
• Support of eDP 1.3
• Support of MyDP/SlimPort (SlimPort
is a trademarked implementation of
MyDP by Analogix)
• Measurement process
configurability
• Support of DualMode, or DP++
• Automated scope measurement
setup
• Test results reports with pass/fail
margin analysis
• Automation control through AUX
Channel Controller
• Optional switch control
With the DisplayPort electrical test
software, you can use the same
oscilloscope you use for everyday
debugging to perform automated
testing and margin analysis based on
the DisplayPort-specified test checklist.
