Verify and Debug Your eDP Designs More Easily
The Keysight Technologies, Inc. eDP 1.4 electrical performance and characterization
(EP&C) software for Inniium Series oscilloscopes (see Table 2) provides you with a fast
and easy way to verify and debug your eDP interface designs for embedded systems.
The eDP 1.4 electrical test software is designed to be uniquely exible to handle
the wide variety of congurations that are possible in embedded systems and pose
characterization challenges. It offers the standard tests that are recommended as well
as other informative tests, so it functions equally well as a validation tool. It displays
the measurement data results in a exible report format, and the report also provides a
margin analysis that shows how closely your device passed or failed each test.
To make measurements with the eDP 1.4 EP&C, you will also need an eDP TPA xture
for high-speed signal access as well as for AUX channel and other lines of the interface.
Available xtures are identied in Table 5.
The eDP 1.4 EP&C software is based broadly on the widely-industry-accepted Keysight
DisplayPort application, which extends utility to include a wizard graphic user interface
that enables test selection, parameter election, test specication entry, and test
template sharing. These features are unique in the industry and are supported to enable
ecosystem sharing of test process specics for highly variant embedded designs.
There is no ofcial interoperability program for eDP 1.4, though this software goes a long
way to create a defacto program – if only for a specic product or family of products. The
default specications are those found in the VESA
1
test guideline eDP PHY CTG v1.0. The
tests available in the eDP 1.4 EP&C software package are identied in Table 1. However,
there is no limit to what tests you can have available with the Inniium framework add-in
feature, with which you can add your own tests or tests from colleagues to the test suite
offered. Details of the add-in capability are covered in the Extensibility section below.
