Abstract
A method and device for determining the impedance of the electric and magic fields in the near and far fields associated with a radiating antenna. The electric and magnetic field components are sensed in a far field location and the system is calibrated using a known relationship between the electric and magnetic field components. The sensed signals are transmitted optically via a fiber optic link to an optical receiver. The received optical signals are modulated by an audio signal generator and input into a ratio detector via variable attenuators which are used to calibrate the system. Multiple subsequent ratios are measured and recorded as a function of location of the sensor.
