CU 303447 – Artificial Antenna
The artificial antenna corresponds to requirements of ETSI EN 303 447. It is equipped with a section of inductance and resistance, which serves as a defined symmetrical termination for the RMI-transmitter. Two built-in current transformers, accessible through the two BNC-connectors ICM and IDM, provide measurement capabilities for both, common mode and differential mode currents. The conversion factor of the current transformers is 1:1, i.e. x dBµA is indicated as x dBµV in the 50 Ω-system. The frequency response of the current transformers is flat with a negligible ripple of less than ± 0.1 dB above 150 kHz.
