TekExpress 400G-TXE created changes on your system. After first launch of "TekExpress 400G-TXE.exe" following changes take place in your Scope. a) "My TekExpress" folder is created under "My Documents" folder of current user NOTE: If a user with new login ID launches "TekExpress 400G-TXE.exe" , "My TekExpress" folder is created under "My Documents" of the new user. b) "Untitled Session" folder is created under "400G-TXE" folder when the application is launched and will be deleted after proper termination of the application. c) If user saves a session then all session files are saved under "400G-TXE" folder accordingly. 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) as this may result in loss of data or corrupted session files. ===================================================================================== 5. What's new in Version 10.1.0 a) 200GBase-CR4 and KR4 suites are updated as per latest 802.3cd specification, Draft3.5. b) fixed defects. ===================================================================================== 6. Recommendations Ensure that all the required instruments are properly warmed up, Signal Path Compensation is performed, appropriate attenuators are used when connecting signal to ATI channels and deskew is done. ===================================================================================== 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 Known Issue a) In pre-recorded mode, symbol rate validation will not occur ; hence user is expected to configure the correct symbol rate in UI =====================================================================================
