==================================================================================
3. TekExpress USB3.1 Tx created changes on your system.
After first launch of "TekExpress USB.exe" following changes take place in your
computer.
- "My TekExpress" folder is created under "My Documents" folder of current user
NOTE: If a user with new login ID launches "TekExpress USB3.1 Tx.exe",
"My TekExpress" folder is created under "My Documents" of the new user.
- "USB" folder is created under "My TekExpress" folder
- "Untitled Session" folder is created under "USB3.1 Tx" folder, note that
every time "TekExpress USB3.1 Tx.exe" is launched "Untitled Session" folder is
created under "USB3.1 Tx" folder and will be deleted after proper termination
of application.
- If user saves a session in TekExpress USB3.1 Tx all session files are saved
under "USB3.1 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.
==================================================================================

7. Known Limitations

7.1 Installer related
- TekExpress and related software are installed on C: drive only.
- User needs to have administrative privilege while installing the application.

7.2 TekExpress application related
- Limits Editor will not show measurement specific units.
- DPOJET Test Method does not set CTLE filter to 0db for short channel in Gen2.
- Progress bar does not indicate the accurate completion status of the measurements.
- When waveforms are loaded manually for 'Use pre-recorded waveform files' ensure that
'Data + and Data -' in 'Acquisitions' panel for 'Acquire live waveforms' mode' are selected
as per the 'Single Ended' channel waveform names.

7.3 Others
- USB3.0 USB-IF fixtures are required for USB3.1 Gen1 testing.
- We do not recommend Tektronix USB3.0 fixtures for compliance testing.
- Oscilloscope as 'Toggle setup' using aux toggle is not reliable, use AWG or AFG instead.
- Recalling a session saved from the previous releases (v6.0 till v10.2) will not work.
- Programmatic Interface commands have been modified in the latest version, refer OLH for more details.
- Refer to DPOJET, SDLA and SigTest readme(s) for their respective limitations.
==================================================================================
8. Notes
- Ensure the 'Session Name' given is less than or equal to 20 characters and DUTID given less than
or equal to 10 characters.
- The waveform name, results panel, test report will have, 'Lane' set as Lane1 by default for
'Connector' Standard / Micro.
- Waveform naming convention used from this release is as given below:
For 5 / 10 Gbps measurements:
CPx_Lanex_Measured_Genx_TesMethod_Channel_Run1.wfm (When 'Test Point' is
'Compliance TP1 - Far End')
CPx_Lanex_Probed_Genx_DPOJET_Channel_Run1.wfm (When 'Test Point' is
'Tx Pins - Near End / Custom')
CPx is CP0 / CP1 / CP7 / CP9 / CP10
Lanex is Lane1 / Lane2 (When 'Connector' is 'Type C' for others it is Lane1)
Genx is Gen1 / Gen2
TestMethod is DPOJET / SIGTest (USB-IF)
Channel is Long / Short
For Tx EQ measurements:
Preshoot and DeEmphasis tests CP13, CP14 and CP15 waveforms are acquired and saved. Signal validation, if turned ON will be done only for CP13.
CPx_Lanex_Measured_Gen2_Channel_Run1_Pxx_d_001.wfm (Pxx is Preset P00 for CP15, P01 for CP13 and P02 for CP14)
For LFPS measurements:
LFPS_Lanex_Chx_Genx_Channel_Run1.wfm (Chx is selected Data+ channel and Data-channel)
LFPS_Lanex_Measued_Genx_Channel_Run1.wfm (When 'Test Point' is 'Compliance TP1 -Far End')
LFPS_Lanex_Probed_Genx_Channel_Run1.wfm (When 'Test Point' is 'Tx Pins - Near End / Custom')
Additional Information:
CP10 waveform is saved without CTLE to process Rj value. Waveform name has a reference as 'NO_CTLE'.
CP9 waveform is saved without Embed/CTLE. Waveform name has a reference as 'EQ'.
If 'Channel' is selected as 'Both' then CP10, CP13, CP14 and CP15 are saved only for 'Short Channel'.
Channel specific waveforms are saved for CP0 and CP9 to perform 'Common Mode' tests when 'Test Point' is 'Tx Pins - Near End / Custom'.
