The Com-Power CDN-T2 Wire Coupling/Decoupling Networks (CDN) are designed for testing in the range of 150 kHz - 80 MHz according to the EN 61000-4-6 / IEC 61000-4-6 standard for immunity to conducted disturbance induced by radiofrequency fields. As the name implies, the Com-Power CDN-T2 has both coupling and decoupling networks. The coupling network delivers injected RF common mode current disturbance signals through the various conductors to the equipment under test (EUT).

The decoupling networks are used to ensure that the disturbing signals injected on the signal or power line of the EUT by the coupling networks do not interfere with any of the auxiliary equipment (AE) connected to the EUT. Each Com-Power CDN-T2 contains integrated direct capacitive coupling along with a high impedance choke for inductive decoupling. The disturbing signal can be injected on signal lines and power lines of a EUT by using the appropriate CDN described below. The setup must be calibrated to establish the drive table. Please use the appropriate calibration components for this CDN — you will need:

  • 2 units of the 150 Ω to 50 Ω adapter
  • Calibration adapters
  • 1 unit of the 50 Ω Terminator
  • Optional Ground plane
T series CDNs for unshielded balanced pairs

The T series CDNs are for cables with unshielded balanced conductor pairs typically found in ISDN, DSL, and 10/100 baset T data transfer applications.
