Fischer Custom Communications Coupling Decoupling Network (CDN’s)

The common mode current disturbance signal can be delivered to the EUT using a variety of coupling networks to inject the signal onto the unscreened cables, shielded cables, balanced cables, coaxial cables and power mains. Decoupling networks are used to insure that the disturbance signal does not influence the auxiliary equipment and are placed between the EUT and the auxiliary equipment. FCC (Fischer Custom Communications) offers a broad range of Coupling Decoupling Network  for testing different port types, like power lines, balanced and unbalanced lines, coaxial lines and audio ports.



The M-Series power line CDN are used to couple common mode CW and modulated signals onto power lines systems. Available with 1,2,3, 4 or 5 lines with current ratings of 16, 25, 32, 50, 100, and 200 amperes
The T series CDN is used to couple RF CW and modulated signals into balanced or unshielded lines
The S Series CDN is used to test shield cables and is available with 2 to 50 pins.
The C series CDN is used to couple RF interference signals onto shields of RF coaxial cables.
The AF series is ideal for unshielded audio cables and is available with 2 to 50 pins.
