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. 5.1 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. 5.2 What's new in Version 10.2.0 a) Measurement procedure corrected for Normalized coefficient step size Measurements. b) Fixed PAM4 configuration 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 =====================================================================================
