3. TekExpress USB3 Tx created changes on your system.
After first launch of "TekExpress USB.exe" following changes take place in your
a) "My TekExpress" folder is created under "My Documents" folder of current user
NOTE: If a user with new login ID launches "TekExpress USB3 Tx.exe",
"My TekExpress" folder is created under "My Documents" of the new user.
b) "USB" folder is created under "My TekExpress" folder
c) "Untitled Session" folder is created under "USB3 Tx" folder, note that
every time "TekExpress USB3 Tx.exe" is launched "Untitled Session" folder is
created under "USB3 Tx" folder and will be deleted after proper termination
of application.
d) If user saves a session in TekExpress USB3 Tx all session files are saved
under "USB3 Tx" 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.
c) Scope should be deskewed with bandwidth set to 13G for all channels before testing.
d) For Gen2, it is recommended to use Ch1,Ch3 or Ch2, Ch4 to get 100GS/s sample rate.
Otherwise Gen2 (10Gbps) measurements will run on 50GS/s.

5. Supported Tests

7. Known Limitations

7.1 Installer related limitation
a) Installation of TekExpress 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 application related limitation
a) When running USB3 Tx tests, if no signal is connected, then during DPOJET Vertical autoset,
the DPOJET/scope may not respond since it waits for ever for a signal. If in between the signal
is connected, then the execution proceeds normally. To overcome this error, please ensure that
the signal is connected before starting the measurements.
b) It has been seen that sometimes even with valid signal, the DPOJET Autoset hangs.
This primarily happens if the user tries to access the scope graticule when autoset is
happening. Hence it is advised that the user must not access the scope graticule when DPOJET
Autoset is happening.
c) Make sure a filter file is selected when the user checks the respective filter option.
d) Limits Editor will not show measurement specific units and for LFPS tests '_10Gbps' prefix is added.
8. Information

a) New [email protected] and [email protected] measurements for USB3 Gen2 with ‘locked Rj value processed from CP10 without CTLE’ in LIVE signal tests.
b) In Pre-Recorded Mode, the Rj is locked to default of 1ps for [email protected] and [email protected] calculation.
c) In LIVE mode, if only [email protected] / only [email protected] / only [email protected] and [email protected] calculation selected, the Rj is locked to default of 1ps
