Test Equipment Description

Haefely DEC 6 Decoupling Network Description:

The Haefely DEC 6 is used for decoupling auxiliary equipment from an EUT tested with 10/700us impulses up to 6.6kV peak. It is used to decouple unshielded symmetrical data and signal lines according standard ITU K.44. Up to 4 wires can be tested simultaneously.
To obtain maximum flexibility only decoupling and protection elements are included in the DEC 6. Coupling circuits, which depends on the EUT to be tested, can be placed separately in the test setup.
Manual coupling selection of the protection elements for best protection of the auxiliary equipment.
Default protection elements are gas arrestors and breakdown avalanche diodes (ABDs). 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.
The DEC 6 can be used together with the coupling networks PCD 120, PCD 122 and PCD 800. These provide all the coupling elements as required to perform IEC, ANSI, FCC and EN testing.

Haefely DEC 6 Decoupling Network Applications:

  • Unshielded symmetrical data and signal lines
  • Telecommunication equipment
  • Other international requirements for surge testing symmetrical data
  • and control lines such as TIA 968 A (FCC part 68)
Specifically designed to meet and exceed the requirements of:
  • EC / EN 61000-4-5 Edition 1 Figure 12 (*)
  • IEC / EN 61000-4-5 Edition 2 Figure 14 (*)
  • IEC / EN 61000-4-12 Edition 2 Figure 12 (*)
