PCD 122 - Coupling Network for Symetrical Data And Control lines
The Haefely PCD 122 is used for coupling of 10/700μs impulses up to 6.6kV peak onto unshielded symmetrical data and signal lines according IEC/EN and ITU standards. Up to 2 pairs / 4 wires can be tested simultaneously
To obtain maximum flexibility, only coupling elements are included in the PCD 122. Decoupling circuits, which depend on the EUT to be tested, can be placed separately in the test setup.
Manual coupling path switching for common mode (longitudinal, line to earth) and for differential mode (transverse mode, line to line) testing.
Default coupling elements are gas arrestors and breakdown avalanche diodes. The coupling elements can be selected easily. The direct coupling output allows the customer to use their own coupling elements.
