Tektronix launches solution for gigabit Ethernet compliance testing

LinkedIn +

Measurement system specialist Tektronix has launched the TekExpress multi-gigabit automotive Ethernet compliance test solution. The company notes that as newer automotive technologies such as autonomous driving, 5G and connected car solutions 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 compliance test application, Tektronix’s new solution enables 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 10Gb/s. The fully automated compliance test solution complies with the current version of the IEEE 802.3ch MultiGBASE-T1 specification. The company notes that as the solution uses its existing automation framework, engineers do not have to learn a new software interface.

Raajit Lall, general manager of market solutions at the company, explained, “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. 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.”
