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: "\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" "\My Documents\My TekExpress\DisplayPort\Untitled Session", This sub-folder is created every time the "TekExpress DisplayPort.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. c) Install the installer in the DUT in case you are using Alpine Ridge DUT and control the DUT using Tenlira interface. ================================================================================= 3. TekExpress DisplayPort created changes on your system. After first launch of "TekExpress DisplayPort.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 DisplayPortTx.exe", "My TekExpress" folder is created under "My Documents" of the new user. b) "DisplayPort" folder is created under "My TekExpress" folder c) "Untitled Session" folder is created under "DisplayPort" folder, note that everytime "TekExpress DisplayPortTx.exe" is launched "Untitled Session" folder is created under "DisplayPort" 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" 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 6.1 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. 6.2 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. e) Don't run DPR-100 utility and TekExpress DisplayPort simultaneously. 6.3 TekExpress application Known issues a) Session files from previous release are not compatible in this new version b) Some .net interface PI commands supported in previous release may not work in the latest release c) Test IDs do not match with the CTS version d) DP-2656: TJ for HBR3 is not executed when CTLE,DFE option is selected for Eye diagram e) DP-2639: If DFE tool is not present in the scope, TekExpress exits without report error message f) DP-2918: Acquire/Analyze 3 times in preferences panel does not work for eye diagram using DFE tool
