Introduction The Tektronix TekExpress DisplayPort 2.0 is an automated test solution for Pre-Compliance testing with Standard and Type-C connectors as per Spec 2.0. ================================================================================= 2. Features - Complete Pre-compliance testing of data rates UHBR10, UHBR13.5, and UHBR20 for DP2.0 Source devices (Standard and Type-C connectors) - Supports P0 to P15 presets for signal test - Supports both TP2 and TP3 EQ test point testing. Use SDLA for TP3 EQ test point analysis. - Optimized algorithms to execute tests with improved accuracy - Supports measurements that are not supported in CTS (SSC measurements, Unit Interval Measurements, LFUDJ Measurements) - Support P7625 and P7633 differential probes - Fixture De-embedding in differential and single-ended mode by creating a custom filter file using SDLA software to leverage the channel modeling and receiver equalization functionality. - Selective testing: - Selection of specific or all data rates. - Selection of tests individually or in groups. - Selection of specific presets for individual measurements. - Selection of SSC On, Off, or Both. - Quick testing: - Support for using saved setup for testing. Avoids overhead of doing the setup for every run. - Support multi-lane testing on one go. - Analyze multiple data rates and multiple presets on one go. - Analyze TP2 and TP3 EQ test points on one go. - One-click selection of multiple tests ensures faster testing. - One-click report format change - Avoids repeated testing through accurate and reliable results from a single run - Supports multi-run feature for test repetition with the same setup - Supports signal validation option to detect anomalies in the signal before analysis - Supports offline analysis of the saved waveforms in Pre-Recorded mode - Detailed test reporting: - Exports available in .mht, .pdf and .csv formats for advanced data analysis - Provides a Pass/Fail summary table - Provides compliance report - Provides limits and margin details on each test - Provides all results, grouped by features - Provides a consolidated report for all tests • DisplayPort 2.0 DPOJET plug-in solution provides the MOI and setup files for debugging and characterization. ================================================================================= 3. Before you click "RUN" a) Ensure that all the required instruments are properly warmed up, Signal Path Compensation (SPC) is performed, followed by calibration and cable deskew. b) Steps for network drive connection 1) Background information : After you first launch TekExpress, it creates the following folders on your computer: "\My Documents\My TekExpress" NOTE. Ensure that the "My TekExpress" folder has Full read and write access. NOTE. If a user with a different Windows login ID launches TekExpress, a new folder is created under "My documents" of new user. "\My Documents\My TekExpress\DisplayPort 2.0" "\My Documents\My TekExpress\DisplayPort 2.0\Untitled Session", This sub-folder is created every time the "TekExpress DisplayPort 2.0.exe" is launched and this sub-folder is deleted when you exit application. CAUTION: Each session has multiple files associated with it. Do not modify any of the session files and/or folders as this may result in loss of data or corrupted session files. The "My TekExpress" folder mentioned above is created as a shared folder with share name as 's My TekExpress. ================================================================================= 4. TekExpress DisplayPort 2.0 created changes on your system. After first launch of "TekExpress DisplayPort 2.0.exe" following changes take place in your computer. a) "My TekExpress" folder is created under "My Documents" folder of current user NOTE: If a user with new login ID launches "TekExpress DisplayPort 2.0.exe", "My TekExpress" folder is created under "My Documents" of the new user. b) "DisplayPort 2.0" folder is created under "My TekExpress" folder c) "Untitled Session" folder is created under "DisplayPort 2.0" folder, note that everytime "TekExpress DisplayPort 2.0.exe" is launched "Untitled Session" folder is created under "DisplayPort 2.0" folder and will be deleted after proper termination of application. d) If user saves a session in TekExpress DisplayPort all session files are saved under "DisplayPort 2.0" folder. Note that each session has multiple files associated with it and do not tamper with any of the session file(s) and/or folder(s) this may result in loss of data or corrupted session files. ================================================================================== 5. Supported Tests DisplayPort Pre-Compliance test supports All transmitter tests for Physical Layer Solution in this version of the application. - Eye Diagram Testing - Data Dependent Jitter (DDJ) Measurement - Random Jitter (RJ) Measurement - Total Jitter (TJ) Measurement - Uncorrelated Jitter (UJ) Measurement - Uncorrelated Deterministic Jitter (UDJ) Measurement - Low Frequency Uncorrelated Deterministic Jitter(LFUDJ)Measurement - SSC Down Spread Rate Measurement - SSC Phase Deviation Measurement - SSC Slew Rate Measurement - Unit Interval Measurement ================================================================================== 6. Supported list of equipment, accessories and software Minimum Requirement Scope Model :Tektronix DPO/DSA/MSO70000/DX/SX with BW 21 GHz and above. Supported Probes: P7625, P7633. Probe Tips for P76xx series probes: P76CA-292, P76CA-292C, P76CA-SMP and P76TA. TekScope: 10.12.0 & above (DPO/DSA/MSO 70K DX/SX series only) DPOJET: v10.3.0.5 and above CIO: v1.0.0.64 Displayport DPOJet Plugin : v10.0.0.138 SDLA: v3.0.11.10 and above ================================================================================== 7. Known Limitations 7.1 Installer related limitation a) Installation of TekExpress and other software packages are installed on C: drive only. b) The available free space on C: drive must be minimum 2.2GB. 7.2 TekExpress application related limitations a) Tests will be started only when all the instruments are available. b) During test execution if user pauses the execution and if user does any changes in instrument setup then it is important that user restores the instruments settings to same state before clicking "Continue". c) Need to have sufficient hard disc space(around 4-6GB when full run is selected) to save the session information. d) If an invalid pattern is given for analysis for Non-Preemphasis, Pre-emphasis tests image will have only graticles, waveform image is not shown. 7.3 TekExpress application Known issues a) Pre-requisites: User needs to install SDLA: v3.0.11.10 or above manually. b) DUT automation is not supported. c) Channel selection should be CH1-CH3 or CH2-CH4 to ensure 100 GS/s datarate. d) User defined mode is disabled. e) Optimum CTLE table for TP3_EQ measurements in the report is only visible when the report is grouped by Test Name.
