The fields have been calculated and measured. Immunity as well as emission capabilities have been clearly demonstrated, to be superior to the GTEM and the fully absorber lined chamber. Two septa are driven by the feeding generator. By rotating the generated field mechanically or electrically along the longitudinal axis of symmetry and rotating the EUT on the turn table, always parallel to the laboratory floor, we can measure specific field directions, including polarization angles.
All walls are absorber lined.
Two adjacent electrodes are charged with the same polarity and the remaining ones with the opposite polarity. In this way we can get vertical polarization or horizontal polarization, respectively. The chosen strip line arrangement enables the current to propagate from the balun in a symmetrical manner towards the final termination. The strip line arrangement flares out symmetrically to the longitudinal axis of rotation. Facility investment without equipment ca.
