Automates compliance measurements for USB PWR Specification Rev 1.0 for the following measurements: - AC Voltage Frequency Component - AC CommonMode Voltage - Ripple Voltage - Maximum Slew 2. Reduces the time required to conduct testing 3. Minimizes user intervention when conducting time-consuming testing 4. Provides individual or group test selection by using a tree-structure menu 5. Built-in reporting features: - Provides a Pass/Fail summary table - Provides margin details on each test - Provides a consolidated report for all tests 6. Complete programmatic interface enables automation scripts to call USB PWR functions ================================================================================== 3. TekExpress USB PWR created changes on your system. After first launch of "TekExpress USB PWR.exe", the following changes take place in your computer: a) "My TekExpress" folder is created under "My Documents" folder of the current user NOTE: If a user with new login ID launches "TekExpress USB PWR.exe", "My TekExpress" folder is created under "My Documents" of the new user. b) "USB PWR" folder is created under "My TekExpress" folder c) "Untitled Session" folder is created under "USB PWR" folder, note that every time "TekExpress USB PWR.exe" is launched "Untitled Session" folder is created under "USB PWR" folder and will be deleted after proper termination of application. d) If user saves a session in TekExpress USB PWR, all session files are saved under "USB PWR" folder. Note that each session has multiple files associated with it. Do not tamper or edit 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, a Signal Path Compensation (SPC) is performed on each instrument, followed by calibration and cable deskew. c) It is highly recommended to read the "Troubleshooting" section in the OLH before you click "RUN" d) Ensure that the following software are installed in your system. Microsoft Internet Explorer 7.0 SP1 or above. ================================================================================== 5. Supported Test Suites The following DUT types are supported by this version of TekExpress USB PWR: - Permanent cable DUT - Detachable cable DUT ================================================================================== 6. Known Limitations 6.1 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. e) Installer would need around 1GB of Hard disk space in C:\ Drive. Installer won?t check it automatically. 6.2 TekExpress application related limitation a) User needs to have administrative privilege while launching the application for the 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) The application is best viewed in super VGA resolution or higher video adapter (800x600 minimum video resolution for small fonts or 1024x768 minimum video resolution 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. f) Launching session file by double clicking .TekX file will throw error, however user can open TekExpress application and open the session file. g) Few PI functions will not work in this release - Save session - Recall session - Set Pre-recorded mode h) User will be able to change the compliance parameter values using PI in compliance mode 6.3 USB PWR application related limitation a) While running the tests, USB PWR 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) Saved session can be executed only X:\USB PWR. If the session files are copied to other location application will not work as expected. c) In user-defined mode, if user provides invalid scope settings Tekscope and/or application may crash. d) Ripple voltage configuration issue - 45deg temprature config once selected will not allow user to deselect. User would need to select 25deg to deselect 45deg. 6.4 Pre-requisites for TekExpress USB PWR application a) Microsoft Internet Explorer 7.0 SP1 or later. b) Microsoft Photo Editor 3.0 or equivalent software for image files viewing. c) Adobe Reader 7.0 or equivalent software for viewing portable document format (PDF) files. d) Iron Python 2.7.3 e) PyVISA 1.0.0.25 ==================================================================================
