Introduction The Tektronix TekExpress Automotive Ethernet solution provides automated compliance test support for 100Base-T1 (IEEE Std.802.3bw) and 1000Base-T1 (IEEE Std 802.3bp™-2016) standard for Transmitter electrical specificationsb tests. Details are available in the Online Help. The compliance software allows for complete or selective testing of any of the transmitter electrical specifications including complete Oscilloscope control of the required setups. Software setup flexibility allows for design validation, margin analysis and repeatable compliance testing while reducing instrument setup difficulties. Additionally, the software can generate a comprehensive date-stamped test report with pass/fail results including Oscilloscope display waveforms and data plots. ================================================================================================= 2. 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 b.1) Background information: After you first launch TekExpress, it creates the following folders on your Computer: "..\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. "..\Documents\My TekExpress\Automotive Ethernet\" "..\Documents\My TekExpress\Automotive Ethernet\Untitled Session\", This sub-folder is created every time the "TekExpress Automotive Ethernet.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 ================================================================================================= 3. TekExpress Automotive Ethernet application related changes in your system. After first launch of "TekExpress Automotive Ethernet" following changes take place in your Computer. a) "My TekExpress" folder is created under "Documents" folder of current user NOTE: If a user with new login ID launches "TekExpress Automotive Ethernet", "My TekExpress" folder is created under "Documents" of the new user. b) "Automotive Ethernet" folder is created under "My TekExpress" folder c) "Untitled Session" folder is created under "Automotive Ethernet" folder, note that every time "TekExpress Automotive Ethernet" is launched "Untitled Session" folder is created under "Automotive Ethernet" folder and will be deleted after proper termination of application. d) If user saves a session in TekExpress Automotive Ethernet application, all session files are saved under "Automotive Ethernet" 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.

Known Limitations 7.1 TekExpress Automotive Ethernet Application related limitations * Return Loss and Transmitter Distortion measurements needs Calibration before RUN. Calibration is recommended when there is a change in the setup. * After the calibration click 'Apply' button for Transmitter Distortion and ReturnLoss measurements. * When you recall the Return Loss measurement session file, the Calibration files are not recalled. You need to set/load the Calibration files manually. * You cannot stop or pause Calibration RUN during its execution. (This is applicable for both Return loss and Transmitter Distortion measurement) * In Return Loss calibration, after opening the application, when one of the LOAD, OPEN or SHORT calibration's RUN button is pressed first time, It pops up the message to connect USB with setup files and press the RUN button again to perform the calibration. * In Return Loss calibration, as there is no AUX Channel on the MSO5x series Oscilloscope, the user is given an option to select the channel for Synch Input from the dropdown. This enables running the calibration and the return loss mesurement. * If Oscilloscope has Older version of solution, the Old session file saved at X:\BRR will not be able to load on this build. The New path for solution is 'X:\Automotive Ethernet'. Note: The TekExpress Automotive Ethernet Application is best viewed in super VGA resolution or higher video adapter (800x600 minimum video resolutions for small fonts or 1024x768 minimum video resolutions for large fonts) with 96 dpi display settings. If application is running on instrument with lower resolution then it is recommended to use secondary monitor (e.g. sampling scopes CSA/ TDS/ DSA 8200). 7.2 TekExpress Automotive Ethernet Application Known issues * While printing the MHT report, page layout need to be adjusted to obtain desired level of text and image visibility either by using fit to single page or by printing report on multiple pages or by using large paper size. * If too many times the TekExpress Automotive Ethernet application is stopped manually in between the runs, you might observe some delay in test execution, it is recommended to re-launch the Automotive Ethernet application. * Transmitter Distortion test's Configuration Tab is flashing on click. * for 100 & 1000 Base-T1's MDI Retrun Loss & Trasmitter Distortion test, If signal are connected to scope and user press the RUN button, Appication do not allow to go back. In this case, user need to close the TekExpress from Task Manager and relaunch the application. **** Ensure that the scope is restarted after installing Automotive Ethernet application and for the first time after launch Go to Options --> Instrument Control Settings --> CLICK on Refresh button. This will list the instruments. This step must be prefrom before using the solution. * 100 Base-T1 PSD 'Analyze' user defined mode is not functional. **** Oscilloscope takes a long time to boot, this is due to instruments being discovered through LAN. You can unplug the LAN cable or wait for some time until it launches ================================================================================================= 8. Installer Related Instructions: * TekExpress Automotive Ethernet Application to be installed only on Win10 Scopes. * Installation of TekExpress Automotive Ethernet Application and other software packages are installed on C: drive only. * The available free space on C: drive must be minimum 2.2GB. * Need to have sufficient hard disc space (Minimum of 2GB) to save the session information. =================================================================================================
