4. TekExpress 400G-TXO created changes on your system.

After first launch of "TekExpress 400G-TXO.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-TXO.exe" ,
"My TekExpress" folder is created under "My Documents" of the new user. 
b) "Untitled Session" folder is created under "400G-TXO" 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-TXO"
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. Recommendations

a) Ensure Tekscope application and 80SJNB Application are launched before
   launching TekExpress 400G-TXO application
b) Ensure that all the required instruments are properly warmed up, Mainframe/
   Module Compensation is performed, followed by Instrument Noise calibration. 

================================================================================
6. Known Limitations

6.1 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.
6.2 TekExpress application related limitations 
    a) None
