Tektronix, Inc. released two new software packages that greatly simplify Automotive Ethernet testing, debug and Protocol Decode for use with its 5 and 6 Series mixed-signal oscilloscopes (MSO). Using the new Signal Separation software, automotive engineers can now perform Automotive Ethernet testing without disrupting the ECU system or cutting the Ethernet cable to install a directional coupler, while the PAM3 analysis package provides in-depth insight into signal characteristics at the system level.

As they move toward Automotive Ethernet or IEEE 802.3bw (formerly BroadR-Reach) technology in vehicles accelerate, comprehensive design validation is vital to ensure interoperability and reliable operation across multiple ECUs. Current Automotive Ethernet testing solutions require engineers to install a directional coupler to separate the full-duplex signal. This adds insertion and return loss and makes it difficult to determine if an error is a result of the system or the additional hardware.

To eliminate these problems, Tektronix’ unique Signal Separation software separates the full-duplex signal by looking at voltage and current waveforms from both master and slave test points and provides separated signals using a proprietary algorithm. This method displays true ECU signals without the need for a directional coupler and provides full protocol debug of master and slave ECUs simultaneously. Tektronix Signal Separation software is easy to use, reduces testing costs and improves measurement accuracy. Signal Separation supports full life-cycle Automotive Ethernet testing from design through service. Users can use solution for in-car testing, as well as Signal integrity testing during cranking or other scenarios.
