user NOTE: If a user with new login ID launches "TekExpress SAS.exe",
"My TekExpress" folder is created under "My Documents" of the new user.
b) "SAS" folder is created under "My TekExpress" folder
c) "Untitled Session" folder is created under "SAS" folder, note that
every time "TekExpress SAS.exe" is launched "Untitled Session" folder is
created under "SAS" folder and will be deleted after proper termination
of application.
d) If user saves a session in TekExpress SAS all session files are saved
under "SAS" 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.

e) Ensure that the following software are installed in your system.
- Microsoft Internet Explorer 7.0 SP1 or later.
- Adobe Reader 6.0 or equivalent software
- Tektronix Jitter and Eye Diagram tool
- MATLAB 8.0 (2012b) runtime
f) If you notice that Waveform Distortion Penalty (WDP) measurement is not
enabled then SAS-TSGW option need to be brought separately
g) For enabling pattern validation on CJTPAT, the pattern details need to
provided in the 'CJTPAT_SAS_symbols.txt' file located at
'C:\Program Files\Tektronix\TekExpress\TekExpress SAS\

==========================================================================
8. Known Limitations
8.1 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.
8.2 TekExpress application related limitation
a) User needs to have administrative privilege while launching the
application 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) It is recommended to use a secondary monitor when the application is used.
f) When user hits Run button for the first time after application is
opened, application will take few seconds to load all components. This
