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\PCI Express” “\My Documents\My TekExpress\PCI Express\Untitled Session”, this sub-folder is created every time the “TekExpress PCI Express.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 PCI Express created changes on your system. After first launch of "TekExpress PCI Express.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 PCI Express.exe", "My TekExpress" folder is created under "My Documents" of the new user. b) "PCI Express" folder is created under "My TekExpress" folder c) "Untitled Session" folder is created under "PCI Express" folder, note that every time "TekExpress PCI Express.exe" is launched "Untitled Session" folder is created under "PCI Express" folder and will be deleted after proper termination of application. d) If user saves a session in TekExpress PCI Express all session files are saved under "PCI Express" 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.

Switch Matrix a) By default, when Switch Matrix setup is called, a default configuration will be loaded as per Device Type. b) The default configuration file will always be loaded assuming KeithlyS46T RF switch is being used. The files will support: x6 lanes for System-Board device type of CEM specification x12 lanes for Add-In-Card device type of CEM specification x4 lanes for Host device type of U.2 (SFF-8639) specification x4 lanes for Module device type of U.2 (SFF-8639) specification x12 lanes for TX Test Board device type of Base specification c) For Gigatronics switch: Use 'Auto Detect' in the 'Switch Setup - configurations' and continue. d) It is mandatory to RENAME the lanes in-line with application lane naming for TekExpress PCI Express. Ensure the lanes are Renamed as: Lane0, Lane01, Lane02, Lane03, Lane04, Lane05, Lane06, Lane07, Lane08, Lane09, Lane10, Lane11, Lane12, Lane13, Lane14, Lane15. Saving the configuration file will retain the lane names for next use. e) Switch Matrix will not work and not supported for multilane testing using RF switch for Gen4-CEM-Specification. ================================================================================== 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 (Minimum of 1GB) to save the session information. d) On a 25GHz/33GHz oscilloscope, if the Signal amplitude is more than 1.2V and if you are using single ended probe, then the waveform will be clipped. In such cases, use the recommended differential probe. e) Recalling a session saved from the previous releases (v1.0.0 till v10.4.4) is not recommended. f) The option in preference panel to 'Auto close warning and information pop-ups' is not applicable to 'Signal Validation' pop-ups. g) Use only Non-ATI channels on 50/59/70GHz SX oscilloscope models. h) Test only with ONE lane at time for CEM-Specification-System Board, when using Differential / P75xx, P76xx, and P77xx Probes. i) Test only with ONE lane at time for Gen4-Base-Specification-TX Test Board. j) Test only with ONE lane at time for Gen3/Gen4-Base-Specification-TX Test Board, in 'User Define Mode' and selecting de-embedding filter. k) The issue of intermittent behaviour of pattern validation under signal quality test and the non-availability of pattern decoder is known wrt Gen4-CEM and will be addressed in future releases ================================================================================== 8. GRL PCE34 PHY Test Controller 8.1 How to detect GRL Controller on your Oscilloscope If the Oscilloscope is Win10 OS based, when the USB interface of GRL controller is plugged-in the drivers will be loaded automatically and you can detect the instrument using TekExpress Instrument bench by selecting 'Serial' interface check box. For Win7 OS based Oscilloscope the driver must be manually installed one time and similar procedure must be followed to detect the instrument. If this is not coming up in TekExpress instrument bench to TekVisa Instrument Manager and select 'Serial' as ON and then click on update then. The TekExpress PCI Express can detect the GRL controller when the instrument returns the string as “IDN GRL PCIe CEM Controller version 1.4 Release 1” sometimes the controller returns only partial string in response to "IDN?" from TekExpress Instrument bench, then refresh twice. Sometimes the GRL controller may return error in response to "IDN?" - plug-out the USB interface of GRL controller and plug-in to another USB port on the Oscilloscope, if the problem persists... - Restart the Oscilloscope. When TekScope is launched, launch TekExpress and refresh the instrument bench. 8.2 GRL Controller for legacy Gen3 CBB fixture Use the ATX power adaptor cable from the SMPS power adaptor to power cycle the Add-In-Card DUTs Connect the SMA-SMP cable from the GRL controller to RX Lane + and - respectively 8.3 GRL Controller for Gen4 CBB fixture Connect the cables from GRL Controller to Gen4 CBB Rev2.0 respectively Blue - J76 - Toggle Automation Input, check the ^ mark on the pin and this should go the Anode pin side Red - J101 - Reset Automation Input, check the ^ mark on the pin and this should go the Anode pin side Green - J102 - Power Automation Input, check the ^ mark on the pin and this should go the Anode pin side Connect the SMA-SMP cable from the GRL controller to RX Lane + and - respectively 8.4 GRL Controller for Gen3 / Gen4 CLB fixture Connect the SMA-SMP cable from the GRL controller to RX Lane + and - respectively 8.5 Schematic update with GRL Controller Only Gen4 schematics for Add-In-Card and System-Board are updated with GRL controller For Signal Quality Tests, Preset Tests and PWJ Test (Only for Add-In-Card) 8.6 Order request and support GRL PCIE34 Controller for automatic test pattern toggling and DUT power cycle (for Add-In-Card) Part number: GRL-PCIE34-P1 Contact GRL at support@graniteriverlabs.com for support and quote@graniteriverlabs.com to request for a quote. ==================================================================================
