TekExpress, a multi-gigabit automotive Ethernet compliance testing application, confirms the integrity of faster signals at higher data transfer rates.

Tektronix has launched its TekExpress™  multi-gigabit Ethernet compliance test system claiming to be the first-in-market to meet the requirements of complex automotive designs. As newer automotive technologies such as autonomous driving, 5G and connected car systems develop, the paths carrying the vast amount of data necessary to support those technologies must be tested to ensure reliable transfers between a vehicle's electronic sub-systems.

As an automated Ethernet compliance test application, TekExpress allows for quick, accurate and reliable validation and debugging for multi-gigabit Ethernet chipsets and electronic control units (ECUs) to meet Physical Media Attachment (PMA) transmitter measurement requirements for up to 10 Gb/s. The fully automated compliance test system fits the current version of the IEEE 802.3ch MultiGBASE-T1 specification.

"Multi-gigabit Ethernet uses PAM4 modulation to achieve high data rates and reliability, pushing the boundaries of signal integrity and requiring higher performance measurements for compliance, debugging and validation. Debug tools like DPOJET and PAM4 Analysis also allow for quick identification of the root cause of a failure, saving time and effort," shares Raajit Lall, General Manager of Market Solutions. "Tektronix continues to actively participate in the Open Alliance, using our engineering expertise to drive the development of in-vehicle network test specifications and methodologies to ensure reliable, cost-effective testing."

This new Tektronix offering is part of its family of industry-leading automated compliance systems for automotive Ethernet, working seamlessly with Tektronix oscilloscopes. And, because this new application uses the TekExpress automation framework, engineers do not have to learn a new software interface. This new application enhances Tektronix's existing in-vehicle network offering of 10BASE-T1S, 100-BASE-T1 and 1000BASE-T1 compliance testing applications for automotive Ethernet standards.

The Tektronix IEEE 802.3ch Multi-Gigabit Ethernet automated compliance application is now available globally for 10G/5G/2.5GBASE-T1 automotive Ethernet Physical Media Attachment (PMA) transmitter compliance testing on DPO70000 SX/DX Series oscilloscopes.
