Coupling/Decoupling Network (CDN) CDN S Type

  • Designed for IEC/EN 61000-4-6
  • Ready for USB 3.0
  • Compatible with USB 1.0, 1.1 & 2.0
  • Universal solution with connector type “A“

Specially designed to test the universal serial bus (USB) this CDN is fitted with USB 3.0 “A“ type connectors on EUT and AE port. The wide application range is given by the compability of the USB 3.0 “A“ type connector to older USB versions like 1.0, 1.1 and 2.0. Used connectors and cable fulfil the Superspeed (USB 3.0) specification. If the application runs with Superspeed is not only related to the used cable and its length and quality. Tests have shown that any cable extension could not allow the data transfer between two USB 3.0 classified devices.
