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. and IEEE P802.3bw
D3.3 for 100 Base-T1 and IEEE P802.3bpTM 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-to-point
technology for automotive applications.
TM
Key features
■
Fully automated application with setup wizard, to perform compliance testing
as per the Automotive Ethernet 1000Base-T1TM (802.3bp) and IEEE
P802.3bwTM (100Base-T1) standards.
■
Compliance testing to perform signal qualification
■
Automated report generation with Pass/Fail results along with screenshot of
the waveform(s).
■
The 100/1000Base-T1 specification defines Return Loss measurement that
requires a Vector Network Analyzer (VNA). TekExpress Automotive
Ethernet application offers you a patented Return Loss measurement, which
allows you to perform the measurement without using a VNA.

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 DPO/DSA Oscilloscope's GPIB menu. For ease of use, connect to an external (secondary) monitor.

Operating basics
Start the application
To launch the TekExpress Automotive Ethernet application, select Analyze >
TekExpress Automotive Ethernet from the TekScope menu.
The oscilloscope opens the TekExpress Automotive Ethernet application:
When you run the application for the first time after installation, the application
checks for Resources.xml located in the C:\Users\<username>\Documents\My
TekExpress\TekExpress Automotive-Ethernet\ folder. The Resources.xml file
gets mapped to the X: drive when the application launches. Session files are then
stored inside the X:\TekExpress Automotive-Ethernet\ folder. The Resources.xml
file contains information about available network-connected instruments. If the
application does not find the file, it runs an instrument discovery program to
detect connected instruments before launching TekExpress Automotive Ethernet.
To keep the TekExpress Automotive Ethernet application window on top, select
Keep On Top from the Options menu. If the application goes behind the
oscilloscope application, click Analyze > TekExpress Automotive Ethernet to
bring the application to the front.
