Decoupling Network | DEC 5 / 6 / 7
IEC/EN 61000-4-5
IEC/EN 61000-4-12
ITU K.44
The DEC 5, 6 and 7 are used to decouple auxiliary equipment from an EUT, which is tested with various pulses (see technical data). The DEC 5 and 6 decoupling networks can be used to decouple unshielded symmetrical data/signal lines, the DEC 7 can be used to decouple unshielded asymmetrical data and signal lines. Up to 4 lines can be tested simultaneously.
Coupling circuits that depend on the EUT under test can be placed separately in the test setup. Manual coupling selection of protection elements for best protection of auxiliary devices. Default protection elements are gas arrestors and breakdown avalanche diodes. With such elements the capacitive load to the EUT lines is small. The decoupling elements can be selected easily. It is also possible to test without any protection elements. They are suitable for AXOS combination devices from Haefely and can be combined with the PCD coupling networks.
