The paper describes two types of compact fiber-optic links designed to provide dielectric isolation and noise immunity to the interconnection of subminiature microwave field-sensor probes and remotely located test equipment. The system measures the microwave signal levels leaking into partially shielded electronic packages. The fast-rise link rise time 3 ns is for use where the microwave irradiation source produces radar-like short pulses. The high-sensitivity link input noise level 3 micro V is for use with laboratory 1-kHz mdoulated microwave sources. The transmitters are the size of a gum eraser, 1 14 x 1 14 x 2 38 in. The 15-V dc power for the transmitters is obtained either from the system under test or a small NiCd battery.
