Ethernet testing

Ethernet requires specialized test and measurement solutions for a wide range of possible applications

The IEEE 802.3 Ethernet is the most widely used standard for network technology in the world. Applications range from industrial Ethernet for automation and processes to high-speed and ultra-high-speed networking in computer systems and data centers.

The real-time needs of IoT and autonomous driving are pushing the rapidly growing demand for time-sensitive networking (TSN). Dedicated test and measurement procedures are required to analyze protocols, delays and latency in TSN systems

Rohde & Schwarz provides leading-edge solutions for Ethernet physical layer compliance, protocol debugging and timing measurements in TSN networks.
