Teseq CDN T Series Coupling Network for Unscreened Communication/Data Lines

IEC / EN 61000-4-6 specifies the design and performance of a range of coupling / decoupling networks (CDNs). Each CDN is specific to the type of cable and the intended signal carried on the cable. Teseq offers an extensive range of CDNs which fully comply with the requirements of the standard and provide a simple and reliable method of injecting RF energy into the equipment under test (EUT).

Teseq CDN T210A, T240A, T246A, T410A, T411A, T440A, T442A, T443A, T444A, T445A and T4A series is specially designed for testing single pair, with CDN T4xxA single and double pair, applications. Each CDN T2xxA and CDN T4xxA consist of one basic network (CDN T200A and CDN T400A) with D-Sub-25- connectors. The connections to a different pin configurations of the modular connectors (RJ11 / RJ45) in use is performed in adapters. An adapter set (ADR Txxx) consists of two same connecting adapters for the EUT- and AE- port and at least one set is part of each CDN of this series. Additional adapter sets are available. Teseq offers different kinds of CDN, prepared for the most important fixed pin- arrangements of RJ11 / RJ45- connectors and also versions for customer’s specific configuration.

Teseq CDN T8 is designed for tests on up to four unscreened balanced pairs. It consists of one basic network (CDN T800) with D-Sub-25- connectors and two adapter sets (ADR Txxx) for RJ11 and RJ45. An adapter set (ADR Txxx) has two similar connecting adapters for the EUT- and AE- port. The ADR T800 gives the connection to RJ45 sockets with pin-arrangements of EIA / TIA T568A respectively T568B. The adapter set ADR T811 offers application for RJ11.

The Teseq CDN T2-10, T4-10 and T8-10 series is specially designed for testing at a 10 kHz start frequency as required by standards like Namur NE21 and IEC 60945. Further CDN T2-10 and CDN T4-10 allow testing up to 300 MHz as required by CISPR 15. CDN T8-10 is made for four unscreened balanced pairs, allows testing up to 230 MHz and supports Ethernet with 1000BaseT. EUT and AE port are supplied with RJ45. CDN T2-10 and CDN T4-10 are supplied with 1 mm banana sockets for easy adaptation for different single pair, with CDN T4-10 double pair, applications.
