FCC Coupling & Decoupling Networks Catalog

Introduction：

FCC's full name is Fischer Custom Communications, Inc., EUTTEST is an authorized agent of the U.S. FCC company, the agent sells the U.S. FCC coupling and decoupling network products: CDN-M sequence, CDN-AF sequence, CDN-C sequence, CDN-S sequence, CDN-T sequence of five different sequences of Coupling and decoupling network test equipment, all in line with theIEC 61000-4-6 and GBT17626.6 standard requirements. The German NAMUR test specification requires a higher level of testing, up to 30V open circuit voltage, which requires a higher power rating than the standard coupling decoupling network of 6-10 watts, the total power rating shall not be less than 40W.

FCC coupling decoupling network design concepts:

• To include the basic insertion loss from the RFI port to the EUT port, 1 kHz 80% modulation and reflection are always present in all CDN circuits made by all manufacturers. Some manufacturers believe their CDNs are capable of 30 volt testing, but do not equip the CDN with the power ratings required for modulation.
• Each of our CDN designs can be customized for up to 75 watts of power, ensuring sufficient coupling capacity above the voltage levels of any other CDN on the market today.
• CDNs act as low-pass filters to prevent susceptible test signals from interfering with auxiliary equipment. A range of coupling decoupling networks are required to match a wide variety of electronic equipment instruments, systems, computers, printers and appliances. The U.S. FCC offers more than 35
• Different coupling decoupling networks and customized configurations are available. All decoupling networks maintain 150 Ω impedance between 150 kHz and 230 MHz.

CDN M-Series Coupling Decoupling Web Catalog - US FCC

The role of the CDN M-Series:For power line coupling: single-phase/three-phase/Δ/Y

US M1 Power Cords CDN are used to couple common mode continuous wave and modulated signals to a single power line system.M1 is ideal for automotive systems using the chassis as a DC loop.M2 is typically used for 2-wire power conductor cables and M3 for 2-wire single phase cables.M4 is used for 3-phase with P.E. and M5 is used for power supplies for 3-phase systems with neutral ground and protective grounding.M4 is used for 3-phase with P.E. and M5 is used for power supplies for 3-phase with P.E. and M5 is used for power supplies for 3-phase systems with neutral ground and protective ground. The US FCC offers over 15 power cord configurations

*: The number of power cables 1/2/3/4/5 means that L1/GND/L2/L3/N can be connected at the same time.

CDN-T8-T4 Unshielded Balanced Coupling Network - US FCC

T-Series: for unshielded balanced cables: 2-wire/4-wire/8-wire

The T series cdn is used to couple RF continuous wave signals and modulated signals to unshielded balanced lines. It allows proper operation of balanced circuits with impedances of 600 Ω @ 1 MHz and 100 Ω @ 250 MHz.

FCC CDN T Sequence-coupled decoupling network

CDN S-Series Shielded Line Coupling Decoupling Networks - FCC - For testing shielded cables

FCC CDN S-Series Shielded Line Coupling Decoupling Networks

CDN C Series Coaxial Line Coupling Decoupling Networks - US FCC: for coaxial cables (with shield)

The C-Series CDNs are used to couple RF interference signals to the shielding of RF coaxial cables. 50 ohms are suitable for RF testing and 75 ohm systems are suitable for video transmission system equipment.

FCC CDN C Series Coaxial Line Coupling Decoupling Networks

CDN AF Series Unshielded Line Coupling and Decoupling Networks - US FCC: For Unshielded Audio Cables

The AF series is ideal for unshielded audio cables and is available from 2 to 50 pins. This CDN allows the transmission of intentional signals with a bandwidth greater than 2 kHz.CISPR 15 uses a variant of this CDN type to extend up to 300 MHz.It is important to check the impedance and the operating frequency of the audio system to prevent effects on the CDN.
