To meet the requirements for measurements with a broadband artificial network (BAN) in the automotive sector, as specified by ISO 11452-7, the isolating capacitor “DC-Block 500” has been developed. It is housed in a robust enclosure and features a BNC socket and a BNC plug, allowing it to be easily integrated into an existing measurement setup.
Precise impedance measurements at high frequencies are always challenging. Therefore, insertion loss is measured instead within a 50 Ω system. A 5 Ω resistor would result in an attenuation of 0.42 dB. If the attenuation is less than 0.42 dB, the resistance is below 5 Ω (Z < 5 Ω). An ideal capacitor would result in an attenuation of 0 dB.
