Welcome
The TekExpress Automotive Ethernet (100/1000BASE-T1) is a compliance test
solution for performing Transmitter electrical specification tests and MDI
electrical specification Return Loss test of the transmitter as per OPEN Alliance
BroadR-Reach (OABR) specification version 3.2. The IEEE P802.3bwTM D3.3 is
for 100 BASE-T1 and IEEE P802.3bpTM is for 1000BASE-T1. These
specifications have a stated objective to provide electrical interoperability for
100/1000 Mbps client and the same electrical test requirements to the Physical
Medium Attachment (PMA) transmitter electrical specifications.
The Automotive Ethernet (100/1000BASE-T1) is an Ethernet-based point-topoint technology for automotive applications.

Operating Basics
AWG/AFG automation
AWG/AFG automation is supported in the TekExpress Automotive Ethernet
(100/1000BASE-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 Automotive Ethernet
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 (100/1000BASE-T1) Printable Application Help 1
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.

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.
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.

View connected instruments: the instrument control settings
Use the Instrument Control Settings dialog box to view or search for connected
instruments required for the tests. The application uses TekVISA to discover the
connected instruments.

Getting Started
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.
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
table. The time and date of instrument refresh is displayed in the Last
Updated field.
