High-Speed Data Testing Solution

Based on a four‑port vector network analyzer, automated signal switching via a switch‑matrix network, coupled with a custom‑designed test fixture that routes the measurement path, and leveraging algorithms and technologies such as rapid calibration, high‑precision de‑embedding, and parallel data processing within an ATE software platform, fully automated testing is enabled for high‑speed data cables—both bare conductors and cable assemblies—with transmission rates of up to 110 Gbps. This capability seamlessly integrates R&D and production testing for a wide range of high‑speed data cables.

Scheme Overview

High-Speed Data Cable Testing Solution

The “Aumiwalker” automated test system for high-speed data cables is built on a four‑port vector network analyzer. By leveraging an automated signal switching matrix and custom‑designed test fixtures to route the measurement paths, combined with advanced algorithms and technologies—such as rapid calibration, high‑precision de‑embedding, and parallel data processing—integrated within the ATE software platform, it enables fully automated testing of high‑speed data cables (both bare conductors and cable assemblies) with transmission rates of up to 110 Gbps. This system seamlessly supports both R&D and production‑level testing of a wide range of high‑speed data cables.
