Patent ID: 6995569

Claim:
A device for electromagnetic characterization of a tested structure ( 2 ) terminated by connectors linked to transmission lines of any impedance, by evaluating, on a predetermined frequency band, distribution parameters of this structure ( 2 ) and characteristic parameters of the spurious radiations of this structure ( 2 ), comprising: an electrical signal generator ( 4 ), means ( 8 ) of transmitting this electrical signal to the tested structure ( 2 ), means ( 6 ) of analysis of the signal emitted by the generator ( 4 ), as well as of the signals reflected by the structure ( 2 ) and of the signals transmitted by the structure ( 2 ), the means of analysis ( 6 ) comprising means ( 41 ) of calculation of the distribution parameters and of the characteristic parameters of the spurious radiations of the tested structure, wherein the electrical signal generator ( 4 ) is a generator of a pulsed signal ( 26 ) whose spectrum is at least as wide as said predetermined frequency band, the generator being adapted for emitting this pulsed signal ( 26 ) at least once, and wherein the means of analysis ( 6 ) comprise means ( 32 ) of temporal filtering of the signals which they receive, for the elimination of spurious signals ( 64 , 74 ).
