Coupling/decoupling network DEC 6

The 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 • Decoupling resistors 200 Ohm • 10/700 us telecom impulses • combination wave 1.2/50 us - 8/20 us impulses • 100 kHz ring wave impulses • Breakdown avalanche diodes and gas arrestors as protection elements • Up to 4 wires can be tested • Signal Bandwidth up to some 10 MHz
