TekExpress® DisplayPort Automated Solution Application Help 9
Welcome
Welcome
The Tektronix TekExpress DisplayPort software supports CTS 1.2 and CTS 1.4. The software uses Tektronix DisplayPort AUX controller
(DP-AUX for standard DP 1.2 DUT) and Unigraf DPR-100 to automate DisplayPort physical layer source compliance tests for Standard
and Type-C connectors. The DP-AUX/ DPR-100 puts the DUT in different test modes and eliminates the need for user intervention during
testing. For Alpine Ridge DUTs, the software automates the TenLira scripts to put the DUT into different test modes.
Tektronix provides various tools such as DPOJET (Jitter and Eye Analysis tool), SDLA (Serial Data Link Layer Analysis), and DisplayPort
essential (DisplayPort measurement library) to perform the characterization/debug of the silicon, and TekExpress DisplayPort application to
perform the compliance tests.

input, which offers the most efficient test configuration, by offering inputs for all 4 differential DisplayPort signals concurrently. This
configuration precludes the testing of common mode and skew measurements.
TCA-based single-ended input (direct Tektronix oscilloscope inputs) supports both differential and single-ended tests including intra-pair
skew measurements on up to 2 concurrent DisplayPort signals. 4 lane TCA based single-ended input is supported using RF Switch.

Introduction to the application
DisplayPort Tx application overview
ekExpress is the Tektronix Test Automation Framework, developed to support your current and future test automation needs. TekExpress
T
uses a highly modular architecture that lets you deploy automated test solutions for various standards in a relatively short time.
The Tektronix TekExpress DisplayPort software supports CTS 1.2 and CTS 1.4. The software uses Tektronix DisplayPort AUX controller
(DP-AUX for standard DP 1.2 DUTs) and Unigraf DPR-100 to automate DisplayPort physical layer source compliance tests for Standard
and Type-C connectors. The DP-AUX/ DPR-100 puts the DUT in different test modes and eliminates the need for user intervention during
testing.
Key Features: DisplayPort Tx has the following key features
• Fully-automated compliance testing of DP1.4 source devices (Standard and Type-C connectors).
• Support for Dual Mode (DP++) and AUX channel tests.
• Support for running automated tests through TenLira scripts for Alpine Ridge DUTs.
• Integration with Tektronix DP-AUX (for standard DP 1.2 DUTs) or Unigraf DPR-100.
• Automatic insertion of modelled channel losses, CTLE equalization and DFE as per the CTS.
• User-Defined mode for characterization, margin testing and debugging (in addition to compliance testing).
• Support for P7625 and P7633 TriMode probes.
• DP-AUX or Unigraf DPR-100 provides DUT control for full automation, saving hours of manual DUT settings.
• Greater bandwidth allows for increased resolutions, higher refresh rates, and greater color depth.
• Automated testing:
• Minimizes user intervention when conducting time-consuming testing.
• Reduces the time required to conduct testing.
• Selective testing:
• Performs fully-automated testing for transmitter measurements.
• Allows selecting test individually or in groups.
• Avoids repeated testing through accurate and reliable results from a single run.
• Quick testing:
• One-button selection of multiple tests ensures faster testing.
• One-button MHT report format saves time.
• Complete Solution: Complete compliance solution with an elaborate test fixture and support for SMA probing provides a cost-effective
way to perform compliance testing.
• Customize the setup:
• Modify the test setup according to the DUT configuration.
• Run tests using different record lengths.
• Run test measurements using more than one signal.
• Detailed test reporting:
• Provides a Pass/Fail summary table.
• Provides Compliance report.
• Provides margin details on each test.
• Provides all results, grouped by features.
• Provides a consolidated report for all tests.
• Provides additional information such as skew, alignment, and signal type selected for each measurement.
