As key sectors such as industrial internet, intelligent vehicles, and rail transportation accelerate their digital, networked, and intelligent transformation, Time-Sensitive Networking (TSN) technology has emerged as a core enabler across these industries, offering deterministic transmission, compatibility, openness, and low cost. Consequently, a wide range of TSN chips, switches, end devices, and comprehensive solutions are rapidly emerging. From development to deployment, these products require rigorous and reliable testing to ensure performance meets both standards and application requirements. However, TSN testing has long been challenged by high complexity, steep expertise requirements, low equipment integration, and difficulties in coordination and synchronization. Large-scale networking and system-level testing are particularly cumbersome and expensive, often requiring multiple test instruments to be combined and calibrated.

XGTime Technology Co., Ltd. (hereinafter referred to as XGTime) has independently developed the NetSeek 3000/6000 TSN Analyzer. As a next-generation all-in-one TSN test platform, it not only addresses the aforementioned pain points and fills the gap in high-end domestic TSN test instruments but also offers full-scenario coverage and high integration. It represents a systematic solution for TSN testing, providing solid support for the independent and controllable development of China’s TSN industry.

Two Decades of Technical Expertise, Cross-Disciplinary Testing Tool

Founded in 2001, XGtime has over 20 years of deep expertise in high-precision time-frequency testing. Its products are widely used in key industries including research institutes, military, power, rail transit, and telecommunications, establishing a leading position in time-frequency synchronization.  Leveraging its long-term technical expertise and R&D experience in time-frequency synchronization and Ethernet testing, and through in-depth research into TSN protocol standards, XGTime has integrated high-precision time-frequency testing, Ethernet testing, and TSN protocol testing into a single, unified test platform.

Unlike traditional test solutions that require multiple instruments to be combined, the NetSeek 3000/6000 TSN Analyzer innovatively integrates five core functions: grandmaster clock simulation, high-precision time synchronization testing, network traffic and protocol testing, network impairment simulation testing, and network controller protocol testing. A single device can cover the full range of TSN test scenarios—including time synchronization, shaping and scheduling, reliability and redundancy, and stream management and admission control—enabling precise testing from chips and terminals to devices and systems, thereby providing end-to-end test support for the entire TSN industry chain.

Full-Scenario Coverage + High-Precision Validation
As an all-in-one systematic solution, the hardware and software of the NetSeek 3000/6000 TSN Analyzer together form its core testing capabilities. The hardware adopts a modular, chassis-based architecture. The NetSeek 3000 (3U/4-slot) TSN Analyzer is designed for R&D and small-to-medium-scale validation, while the NetSeek 6000 (6U/12-slot) TSN Analyzer is suited for large-scale networking, batch, and system-level testing. Users can select configurations as needed to avoid resource waste. The platform integrates a GNSS receiver and a rubidium atomic clock, ensuring nanosecond-level time test precision while synchronizing all functional boards to a common time base, meeting the stringent timing requirements of TSN test cases.

The software ecosystem is equally comprehensive, comprising three software tools: NetSeek Application, Result Analyzer, and FoxATE automation test software. NetSeek Application serves as the main control APP, providing test configuration, statistical analysis, and firmware upgrades. It features a unified configuration wizard and includes built-in test suites such as RFC 2544/Y.1564 and configuration wizards for TSN protocol functions and performance testing (e.g., 802.1Qbv/Qbu/Qci/CB), significantly reducing operational complexity. Result Analyzer supports raw data viewing and PDF/Excel report export. FoxATE enables test case planning, execution, and automated management.


In practice, the platform can precisely perform functional and performance tests on core protocols such as IEEE 802.1AS (time synchronization), 802.1Qbv (time-aware shaping), and 802.1CB (frame replication and elimination). Whether for multi-node synchronization verification, robustness testing under harsh conditions, or fault diagnosis and interoperability validation, the platform provides detailed statistical data and visual analysis results, ensuring that test metrics accurately meet design requirements.

For example, in IEEE 802.1AS testing, it can analyze and display key parameters such as Time Error, Neighbor Rate Ratio (NRR), and Pdelay Turnaround Time (PDTT), and perform template comparison. In 802.1Qbv testing, it can count per-timeslot frame deviation, number of frames received per timeslot, latency, jitter, etc.
Cost Reduction and Efficiency Improvement, Empowering the Entire Industry Chain
In terms of test efficiency, the unified platform of the NetSeek 3000/6000 TSN Analyzer simplifies complex test environments, eliminates timing and accuracy discrepancies among multiple instruments, and significantly shortens test cycles. In terms of cost of use, the integrated solution lowers the technical barrier, and the unified interface and logic reduce the learning curve. Meanwhile, full lifecycle technical support and compatibility assurance avoid the communication overhead of coordinating multiple vendors.

From R&D in research institutes to batch testing on production lines and efficient troubleshooting in operations, the platform adapts to the differentiated needs of multiple industries, including certification testing, intelligent vehicles, chips, and communication equipment. Its automated test capabilities enable unified management of multiple test platforms and batch execution of test cases without manual intervention, saving substantial labor and time costs for enterprises.

Independently Developed in China, Supporting High-Quality Industrial Development
As a key achievement in response to the national strategy for independent and controllable high-end domestic instruments, the NetSeek 3000/6000 TSN Analyzer not only further breaks the monopoly of foreign products but also provides a solid foundation for China’s TSN technological innovation and industrial application with fully self-developed intellectual property.

In the new era of intelligent connectivity, the depth and breadth of TSN technology applications will continue to expand. In the future, as more domestic innovations emerge, China’s TSN industry chain is poised for high-quality development. XGTime remains committed to its core philosophy—"Trust Because of Reliability"—and will continue to drive technological innovation and the iterative advancement of domestic test instruments.
