Abstract

We present, in this paper, pigtailed electro-optic sensors dedicated to the measurement of high-power microwave signals in outdoors conditions. We give results on high-power microwave single-shot pulses obtained with long fiber links (> 20 m) in hard environmental conditions (temperature variations up to 30degC). In these awkward outdoors conditions, we obtain very stable measurements with rms signal fluctuations lower than 0.2 dB. We focus here especially on the design of the temperature-dependent-free system.
