Introduction

The CDN S4 shielded coupling/decoupling network complies with IEC/EN 61000-4-6, is designed for conducted immunity testing of USB transmission lines.

Supporting signal transmission rates up to 1 Mbit/s and compatible with USB Type-A and USB Type-B interfaces, the CDN S4 ensures stable, distortion-free data transmission during testing, accurately reproduces the actual communication status of the EUT, prevents data loss and false judgments caused by interference, and guarantees accurate and repeatable test results. It is widely used in communications, telecommunications, medical, broadcasting and television, railway, information technology, military, aerospace, new energy power, new energy vehicle.

Features

> Support signal transmission rate up to 1 Mbit/s

> Especially for USB transmission cables, USB A for EUT port and USB B for AE port

> Support most industrial communication equipment

> Max. current rating 1 A for wider application coverage
