The NetSeek3000/6000 TSN Analyzer is a next-generation, all-in-one test platform designed for Time-Sensitive Networking (TSN). As an industry first, it integrates five core capabilities: Grandmaster Clock, high-precision clock synchronization testing, network traffic and protocol testing, network impairment simulation, and network controller protocol testing. Building on traditional Ethernet tester features such as traffic generation, analysis, capture, and performance evaluation, its innovative architecture achieves comprehensive breakthroughs in TSN test functions and scenarios. A single device fulfills all TSN testing requirements including clock synchronization, traffic scheduling, network reliability, and network configuration. It enables efficient testing of TSN gateways, switches, endpoints, and chips, as well as system-level evaluation of in-vehicle, airborne, shipboard, mobile fronthaul, and industrial networks. It provides a complete solution for the TSN industry chain, from chip-level validation to network-level assessment.
