Overview
Com-Power CDN-S25 150 kHz - 80 MHz Shielded Cable with 25 Conductors
The signal line Coupling / Decoupling Networks (CDN) are for testing from 150 kHz - 80 MHz according to the EN 61000-4-6 standard for immunity to conducted disturbance induced by radio frequency fields.
The CDN-S25 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 insure that the disturbing signals injected on the signal or power line of the EUT by the coupling networks does not interfere with any the auxiliary equipment (AE) connected to the EUT. Each CDN contains integrated direct capacitive coupling along with a high impedance choke for inductive decoupling.
The disturbing signal is injected on signal lines by using a series of coupling networks represented by series C, S, AF and T.
Individual calibration data will be provided with each CDN. However, test level calibration must be performed on site to determine the minimum required test signal needed to achieve the required voltage levels specified by EN 61000-4-6. The appropriate calibration accessories for conducting the level test is available from Com-Power.
For each CDN you will need:
- Calibration adapters
- 2 units of the 150 Ω to 50 Ω adapter
- 1 unit of the 50 Ω Terminator
- Optional Ground plane
Application
During the test the CDN is connected to the signal cables between the equipment under test (EUT) and auxiliary equipment (AE). The type of cables will determine which CDN to use for the test.
The S series CDNs are for shielded cables with single or multiple conductors. These CDNs are available for testing 1, 2, 4, 9, 15, 25, 36 and 50 conductor cables. These CDNs have D type or BNC connectors for EUT and AE connections.
