AUTOMOTIVE ETHERNET
As cars move towards autonomy and electrification, one thing is certain: the amount of data flowing through them will only increase. Designers are turning to automotive Ethernet, which offers fast, full-duplex communication over a single twisted-pair cable. These higher data rates drive the need for compliance testing to verify interoperability. And full duplex communication complicates signal decoding.
Tektronix oscilloscopes, equipped with analysis software, can help confirm compliance with industry standards, validate performance and observe bus traffic.

TROUBLESHOOTING AND PRE-COMPLIANCE SCANNING
Critical high-speed data flows throughout today’s vehicles over wired and wireless connections, even as EV power systems switch higher voltages and currents. EMI must be managed not only for regulatory compliance, but also to ensure signal integrity.
Pre-compliance EMI scans build confidence and help designers isolate potential problems before formal testing. For troubleshooting interference problems, seeing signals in both the time domain and frequency domain helps connect cause and effect.
Real-time spectrum analyzers are ideal for finding elusive RF anomalies and performing pre-compliance EMI scans.
