Patent ID: 7280190

Claim:
An apparatus for facilitating isolation of defects in a device under test (DUT) comprising: an optoelectronic module configured to convert an optical test signal to an electrical test signal and provide the electrical test signal to the DUT to be reflected by one or more defects located in the DUT if the one or more defects are present in the DUT; an electro-optic probe including an electro-optic crystal to output a polarized optical sampling signal, the polarization being dependent upon the electrical test signal reflected from the DUT to the electro-optic crystal; and an output module configured to receive the polarized optical sampling signal, and produce an electrical output signal as a function of time based at least in part on the polarized optical sampling signal, the electrical output signal adapted to facilitate isolation of the location(s) of the defect(s) in the DUT.
