Electromagnetic field probe having a non-electrical transmission modality

摘要

A probe for measuring an electromagnetic field is described. A sensing element senses the electromagnetic field and generates a sensing signal indicative thereof. The sensing signal is characterized by a first modality. First conversion circuitry coupled to the sensing element converts the sensing signal to a second modality. A transmission medium coupled to the first conversion circuitry transmits the sensing signal in the second modality. Measurement circuitry coupled to the transmission medium receives the sensing signal in the second modality and generates measurement data corresponding to the electromagnetic field.
