Welcome
The TekExpress Automotive Ethernet (100BASE-T1) is an automotive Ethernet
compliance test solution for performing electrical characterization of the BroadRReach transmitter as per OPEN Alliance BroadR-Reach (OABR) specification
version 3.2. The IEEE P802.3bw D3.3 (100BASE-T1) specification has a stated
objective to provide electrical interoperability for 100 Mb/s client interface in
reference to the OABR PHY v3.2 specification. BRR and 100BASE-T1 maintain
the same electrical test requirements as it relates to the Physical Medium
Attachment (PMA) transmitter electrical specifications.
BroadR-Reach (100BASE-T1) is an Ethernet-based point-to-point technology for
automotive applications. It provides five test mode signals for electrical
characterization of the Physical Medium Attachment (PMA) sublayer.

Operating basics
AWG-AFG automation
AWG\AFG automation is supported in the TekExpress Automotive Ethernet
(100BASE-T1) application for the following measurements. Before selecting the
AWG\AFG automation feature, ensure that a GPIB connection is established
between the oscilloscope and the AWG\AFG. The AFG automation depends on
the measurement used for testing.
■
Transmitter Distortion with disturbing signal: AWG\AFG is used to transmit
a disturbing signal. CH1 and CH1_inverted are used.
■
Return Loss measurement and calibration: AWG\AFG is used to transmit a
wide band signal. CH1 and CH1_inverted are used for transmission of the
signal. A marker signal has to be connected to the auxiliary channel of the
oscilloscope (used as trigger source).
How the TekExpress
Automotive Ethernet
Solution automates AWG
\AFG
Automation of the AWG\AFG is taken care in the TekExpress Automotive
Ethernet application in the following way:
1. Refresh the Instruments Control Settings to observe the connected AWG
\AFG through GPIB.
Figure 2: Instrument Control Settings
TekExpress Automotive Ethernet 3.2 Printable Application Help 3
Operating basics
2. Once the AWG\AFG is listed as shown above, go to the Global Settings tab
from the Configuration menu of the Tests. If the AWG\AFG is supported, it
will be listed as a drop-down menu option next to the Automate with AWG
\AFG label. By default, the application will consider the connected AWG to
be used for automation.
Figure 3: Test Selection tab
3. If you do not want to automate the use of an AWG\AFG, select the Do not
use option in the drop-down menu for that parameter, and then start the
testing.
NOTE. If Automate with AWG\AFG is set as Do not use, you will need to
manually copy the AWG\AFG waveforms from the oscilloscope to the AWG
\AFG. Waveforms are available at C:\Program Files\Tektronix\TekExpress
\TekExpress Automotive-Ethernet\AWG Waveforms.

Operating basics
View test-related files
Files related to TekExpress Automotive Ethernet tests are stored in the X:
\Automotive Ethernet\Untitled Session shared folder. In the Automotive Ethernet
folder, each test setup has a test setup file and a test setup folder, both with the
test setup name. The test setup file is preceded by the Automotive Ethernet icon
and usually has no file extension displayed.
Inside the test setup folder is another folder named for the DUT ID used in the
test sessions (the default is DUT001).
Inside the DUT001 folder are the session folders and files. Each session has a
folder and file pair, both named for the test session using the naming convention
(date)_(time). Each session file is stored outside of its matching session folder.
See also
Each session folder contains image files of any plots generated by the test session
and any waveform files if prerecorded waveform files were used during the
session.
The first time you run a new, unsaved session, the session files are stored in the
X:\Automotive Ethernet\Untitled Session folder. Once you name and save the
session, the Untitled Session folder name is changed to the one you specified.
NOTE. By default, test report files are saved in the session folder. You can change
the report file location for a specific test.

You may use AWG automation for Return Loss and Transmitter Distortion
with Disturbing Signal measurements.
■
AFG3100 & AFG3200 (having limit up to 50 MHz) cannot be used for
Return Loss measurements.
■
Without an amplifier, the AWG7000 series generates a maximum voltage of
2 Volt peak-to-peak signal, which cannot meet the 5.4 Volt requirement for
the disturber signal for Transmitter Distortion test.

If TekExpress is running on an instrument having a video resolution lower than 800 x 600. it is recommended that you connect a secondary monitor,
which must be enabled before launching the application.

If TekExpress is installed on a Tektronix oscilloscope, the virtual GPIB port will be used by TekExpress for communicating with oscilloscope
applications. If external GPIB communication devices such as USB-GPIB-HS or equivalent are used for instrument connectivity, ensure that the Talker
Listener utility is enabled in the MSO Oscilloscope's GPIB menu. For ease of use, connect to an external (secondary) monitor.

To refresh the list of connected instruments:
1. From the Options menu, select Instrument Control Setting.
2. In the Search Criteria section of the Instrument Control Settings dialog box,
select the connection types of the instruments to search for.
Instrument search is based on the VISA layer but different connected cables
determine the resource type, such as LAN, GPIB, USB. For example, if you
choose LAN, you can search for all the instruments supported by TekExpress
that are communicating over the LAN. If the search does not find any
instruments that match a selected resource type, a message appears telling
you that no such instruments were found. Click OK to close the message
window.
NOTE. Ensure that the GPIB option is enabled to detect the real time
oscilloscope in the Global Settings tab.
3. Click Refresh.
TekExpress searches for connected instruments.
4. After discovery, the dialog box lists the instrument-related details based on
the search criteria you selected. For example, if you selected LAN and GPIB
as the search criteria, the application checks for the availability of
instruments over LAN, then GPIB.
The details of the instruments are displayed in the Retrieved Instruments
