Data Sheet

eDP Provides a High-Speed, Bi-Directional Data Path Between the System Host and Display

Verify and Debug Your eDP Designs More Easily

The Keysight Technologies, Inc. eDP 1.4 electrical performance and characterization (EP&C) software for Infiniium 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 flexible to handle the wide variety of configurations 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 flexible 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 fixture for high-speed signal access as well as for AUX channel and other lines of the interface. Available fixtures are identified 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 specification entry, and test template sharing. These features are unique in the industry and are supported to enable ecosystem sharing of test process specifics for highly variant embedded designs.

There is no official interoperability program for eDP 1.4, though this software goes a long way to create a defacto program – if only for a specific product or family of products. The default specifications 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 identified in Table 1. However, there is no limit to what tests you can have available with the Infiniium 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.

Features

The eDP 1.4 electrical performance and characterization software offers new and unique capabilities as well as the standard features available with all Keysight Infiniium framework applications:

  • Full physical layer testing of high-speed lanes
  • Verification of link layer physical layer control
  • Test status tracking
  • Measurement process configurability
  • Automated scope measurement setup
  • Bit rate parameters: Nominal value of bit rate, number of bit rates and test line limit for frequency accuracy
  • Level parameters: Nominal value of level, number of levels and test line limits for level accuracy or value of relative change between level settings
  • Pre emphasis parameters: Nominal value of pre-emphasis, number of pre-emphasis settings and test line limits for pre-emphasis accuracy or value of relative change between pre-emphasis settings
  • Eye diagram mask testing: Entry of arbitrary mask through mask files vs. bit rate
  • Jitter testing: entry of arbitrary RJ, DJ, TJ values vs. bit rate
  • Test plan creation: Selection of device conditions to test
  • Test template: Create default templates for device types avoiding re-entry and share complete test process setup with others for consistent settings for same process requirements in different locations
  • Test results reports with pass/fail margin analysis

With the eDP 1.4 EP&C test software, you can finally solve the myriad of test issues that embedded test systems present with one application.

Easy test process definition

The eDP 1.4 electrical performance and characterization software extends the easeof-use advantages of Keysight’s Infiniium Series oscilloscopes and previous DisplayPort standard test software to testing eDP 1.4 designs.

The application will guide you through device setup and test connection with setup wizards to capture all the test process details. In doing so, you will create a tailored process to validate or characterize your device and get exactly what you need.
