Abstract

The present invention relates to a single ended line testing method for qualifying an electrically conducting line. This method includes the steps of sending a plurality of excitation signals from a first end of the line towards a second end of the line and before the sending of this plurality of excitation signals, randomizing each excitation signal of the plurality of excitation signals. Subsequently, measurements are performed, at the first end of the line, of each reflection of the plurality of excitation signals sent towards the second end of the line. Then an inverse randomization on each of the measurements of reflections is performed which is succeeded by determining an average of all the measurements of reflections of the excitation signals. Finally, from the average a qualification of the electrically conducting line is determined.
