Loop antenna 9kHz–30MHz TBLLA-2M
The TBLLA-2M is a large loop antenna (LLA) equipped with three orthogonal loops that meets the requirements of CISPR 16-1-4 and CISPR 15/EN 55015. The LLA is used to measure the current induced by the magnetic field radiated from lighting fixtures. Section 4.4 of EN 55015 specifies the test setup and measurement procedures. The TBLLA-2M has three loop antennas with a diameter of 2 meters arranged vertically on three orthogonal planes (X/Y/Z). These antennas are mounted on a lightweight hollow WPC frame with a total height of 2.5 meters. The lowest point of the loops is 0.5 meters above the ground. Each loop element receives a magnetic field radiation that is perpendicular to the installation surface, generating a voltage signal at the output port of the RF transducer connected to the loop, which is proportional to the strength of the H magnetic field radiation. The TBLLA-2M is equipped with three TekBox TBCCP1-2K70 coaxial RF current monitoring probes (transducers). These probes have a flat transfer impedance characteristic of 0dBΩ (1V/A) over a frequency range of 9kHz to 30MHz at a 50Ω load.
