Introduction The Tektronix USB 2.0 compliance test application (Opt. 5-CMUSB2) and selected Tektronix oscilloscopes provide one-button compliance testing for USB 2.0 devices as specified by the USB-IF. The USB software automates the compliance testing and allows engineers to perform the required tests efficiently and reliably right at their bench. ================================================================================== 2. Features Release (1.2.3) - USB-2646 - ART# 61625 - Fix for Eye Diagram not tested correctly if differential is chosen in Probe Type - USB-2645 - Fix for USB2 launch issue when instrument list gets corrupt Release (1.2.2) - Comprehensive test coverage; select or deselect individual tests - Precise debugging and troubleshooting - USB-IF Signal Quality measurements integrated with TekExpress USB2 - Automated Receiver Sensitivity measurement - User-friendly interface for plot inspection - Minimizes user intervention when performing time-consuming testing - Consolidated report for High Speed, Full Speed and Low Speed measurements - Complete programmatic interface enables automation scripts to call TekExpress USB2 functions - Flexible probe configuration - Comprehensive signal validation check - Automated DUT test mode control - Provided an option to set Trigger settings for Rx Sensitivity and EL22 ================================================================================== 3. Modifications done on your system by TekExpress USB2 After first launch of "TekExpress USB2.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 USB2.exe", "My TekExpress" folder is created under "My Documents" of the new user. b) "USB2" folder is created under "My TekExpress" folder c) "Untitled Session" folder is created under "USB2" folder, note that every time "TekExpress USB2.exe" is launched "Untitled Session" folder is created under "USB2" folder and will be deleted after proper termination of application. d) If user saves a session in TekExpress USB2 all session files are saved under "USB2" 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) If you are executing TekExpress application on PC other than the scope used for testing then please ensure that the network connectivity is established between the PC running the TekExpress and the scope. Map the shared My TekExpress folder as X: (X drive) on scope instruments used in test setup running Microsoft Windows Operating System. This share folder is used to save the waveform files or any other file transfer operations. b) Ensure that all the required instruments are properly warmed up, Signal Path Compensation (SPC) is performed, followed by calibration and cable/Probe deskew. ================================================================================== 5. Supported Tests USB Low Speed, Full Speed and High Speed Normative and Informative tests are supported in this version of the application. ================================================================================== 6. Supported list of equipment, accessories and software Real-time oscilloscopes - Tektronix MSO54,MSO56,MSO58 and MSO64 Tektronix AWG instruments - AWG70001A, AWG70002A, AWG7102, AWG7122B, AWG7122C, AWG5014B, AWG5014C, AWG5012C, AWG5002C, AWG5202, AWG5204 and AWG5208 Probes - Two TCA-SMA adapters - TCP0030A or TCP202/A probe - TDP1500, TDP3500 or P6248 differential probe - TAP1500 or P6245 single-ended probe Host test fixtures - USB2SIGQUAL fixture set (USB-IF host/device SQ) - USB2/3_DD fixture (USB-IF Drop-Droop fixture) - TDSUSBF (Tek fixture) Device test fixtures - USB2SIGQUAL fixture set (USB-IF host/device SQ) - USB2/3_DD fixture (USB-IF Drop-Droop fixture) - TDSUSBF (Tek fixture) Firmware - TekScope 1.6.3 and later Operating System: - Win10 ================================================================================== 7. Known Limitations 7.1 Installer related limitation a) TekExpress USB2 and other software are installed on C: drive only. b) User needs to have administrative privilege while installing the application. c) The available free space on C: drive must be minimum 5GB. 7.2 TekExpress USB2 application related limitation a) TekExpress USB2 session files (with .TekX extension) can only be opened from Options -> Open Test Setup menu. Opening by double clicking on session files is not supported. b) Limits Editor will not show measurement specific units. c) When executing Receiver Sensitivity test with 'differential probe' say P6248, ensure attenuation is set to '1X'. d) Mask margin will be applicable for only 4 & 6 coordinate mask. e) Custom mask is applied in TekExpress plot only. This mask will not be shown in report. f) Use 1.3.0.1 xHCI tool for DUT automation mode. g) Ensure that the scope is restarted after installing the USB-2.0 Application for the first time. After Scope launch go to Options --> Instrument Control Settings menu item and CLICK on Refresh button. This will list the instruments. This step must be performed before using the solution. h) In the Global Configuration Panel, don't change the RealTime Scope value, it can sometimes freeze the UI for 3-4 mins
