The Series AF from Fischer Custom Communications are Coupling Decoupling Networks (CDNs) that operate from 150 kHz to 230 MHz. They are compliant with the IEC 61000-4-6 standard to support conducted immunity testing. These CDNs consist of a voltage attenuation generator and a decoupling attenuation generator. They can handle an input power of up to 12 W and have an insertion loss of 30 dB (test equipment). These systems require an AC or DC supply of 250 V and consume less than 2 A of current. They are available in enclosures that measure 23 x 15 x 13 cm and have a BNC connector.
