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 DPO/DSA/MSO70000C, D, DX and SX series oscilloscopes - Tektronix DPO7000C series oscilloscopes - Tektronix MSO/DPO5000 and MSO/DPO5000B series oscilloscopes Tektronix AWG instruments - AWG70001A, AWG70002A, AWG7102, AWG7122B, AWG7122C, AWG5014B, AWG5014C, AWG5012C, AWG5002C and AWG5200A Probes - Two TCA-SMA adapters (if using DPO/DSA/MSO70000) - 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 10.8.0 and later Operating System: - Win7 and 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) Receiver Sensitivity measurement is not supported on Tektronix MSO/DPO5000 and MSO/DPO5000B Series oscilloscopes. b) 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. c) Limits Editor will not show measurement specific units. d) When executing Receiver Sensitivity test with 'differential probe' say P6248, ensure attenuation is set to '1X'. e) Mask margin will be applicable for only 4 & 6 coordinate mask. f) Custom mask is applied in TekExpress plot only. This mask will not be shown in report.
