Introduction The Opt. SAS3-TSG (TekExpress® SAS Transmitter Automated Solution), supported on DPO/DSA/MSO70000/C and DPO/DSA70000/D models, includes TekExpress automated software (TekExpress SAS Tx) for testing SAS physical layer transmitter testing. TekExpress SAS Tx is an automated test system for testing the SAS compliance/conformance tests. The Installation manual contains the procedure for installation and the online help file included with the software contains the detailed information on how to use the system. This Readme.txt file contains additional information for the user. ========================================================================== 2.

Release v10.2.1 - Changed Limits for Gen1/gen2 Rise/Fall time Release v10.2.0 - Migrated to new TekExpress Framework version 4.0 - Automated Tx test: 25 compliance tests. Refer to the OLH included as part of the installer - Support for SAS Base spec v06 ========================================================================== 3. TekExpress SAS Tx created changes on your system. After first launch of "TekExpress SAS.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 SAS.exe", "My TekExpress" folder is created under "My Documents" of the new user. b) "SAS" folder is created under "My TekExpress" folder c) "Untitled Session" folder is created under "SAS" folder, note that every time "TekExpress SAS.exe" is launched "Untitled Session" folder is created under "SAS" folder and will be deleted after proper termination of application. d) If user saves a session in TekExpress SAS all session files are saved under "SAS" 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. =========================================================================== 4. Before you click "RUN" a) Right click on the "My TekExpress" folder and open the Properties dialog box. Select General tab and then Advanced. In the Advanced Attributes window, ensure that the option Encrypt contents to secure data is NOT selected. b) Ensure that all the required instruments are properly warmed up, Signal Path Compensation (SPC) is performed, followed by calibration and cable deskew. c) It is highly recommended to read Troubleshooting section in OLH before you click "RUN" d) For SSC measurements at Gen3 speed, record length of 50M is recommended. e) Ensure that the following software are installed in your system. - Microsoft Internet Explorer 7.0 SP1 or later. - Adobe Reader 6.0 or equivalent software - Tektronix Jitter and Eye Diagram tool - MATLAB 8.0 (2012b) runtime f) If you notice that Waveform Distortion Penalty (WDP) measurement is not enabled then SAS-TSGW option need to be brought separately g) For enabling pattern validation on CJTPAT, the pattern details need to provided in the 'CJTPAT_SAS_symbols.txt' file located at 'C:\Program Files\Tektronix\TekExpress\TekExpress SAS\ Compliance Suites\Drive\PHY-TSG-OOB' ========================================================================== 5. Supported Test Suites Following test suites are supported by this version of TekExpress SAS: SAS PHY, OOB, TSG Tests ========================================================================== 6. Information a) The version of SAS3_EYEOPENING used is v2.1 b) This version of TekExpress SAS is supported only on Non-ATI channels of the SX oscilloscopes ========================================================================== 7. Pre-Requisites 7.1 Third party Dependency components Version (These will installed as part of the full deployment package except MATLAB runtime that will be installer as part of the DPOJET install package): 1. MS DOTNET framework Ver. 4.0 2. MATLAB Ver. Ver8.0 for Win7 3. Iron Python Ver. 2.7.3 4. PyVISA Ver. 1.0.0.25 7.2 Tektronix Dependency Firmware/Applications Version (These needs to be installed by the End-user explicitly): 1. Real Time TekScope firmware Ver. 10.7.0 and above. 2. DPOJET application Ver. 10.0.5 and above. 7.3 Scope Requirements 1. SAS Gen1 and Gen2 require DPO/DSA/MSO 12.5Ghz C/D models and above 2. SAS Gen3 require DPO/DSA/MSO 20Ghz C/D models and above 7.4 Tektronix Software option keys required : 1. On TekScope : a. SAS3-TSG for SAS-3 Automated Tx Compliance Tests. b. SAS3-TSGW for SAS-3 WDP Transmitter Measurements. ========================================================================== 8. Known Limitations 8.1 Installer related limitation a) Installation of TekExpress and other software are installed on C: only. b) User need to have administrative privilege while installing the application c) Application can only be launched in TekScope. d) Before installing the application, Tekscope application should be closed. 8.2 TekExpress application related limitation a) User needs to have administrative privilege while launching the application first time. b) Test will be started only when all the required instruments are available. c) During test execution if user pauses the execution and makes any changes in instrument setup, then it is important that user restores the instruments settings to same state before clicking "resume". d) DUT ID should have maximum of 32 Characters, even though field allows for more. e) It is recommended to use a secondary monitor when the application is used. f) When user hits Run button for the first time after application is opened, application will take few seconds to load all components. This will cause UI to freeze for few seconds. Repeatedly pressing Stop button will cause the application to hang. g) By default detailed log is always enabled, Hence Checking and Unchecking "Show detailed log" in status tab, has no effect 8.3 TekExpress SAS-TSG and SAS-TSGW application related limitation a) While running the tests, SAS application will go behind the scope during some of the tests. User has to press Alt-Tab to bring the application to the front. b) Install of custom software for putting the DUT into certain mode is not handled in the application. Application expects the Script names used to be appropriately configured before running the application. You can refer to the OLH for more details. c) While the custom script to put the DUT into certain mode is running, the application cannot be stopped. d) In email settings, Score card and Analysis Screen shot functionality are not applicable for this application e) Application does not do pattern validation for OOB and 'Scrambled 0' patterns f) Session of TekExpress will be saved in x:\SAS ==========================================================================
