Locating the degradation of cable insulation
propagation coefficient has many relations for cable.It is clear that there is more “rough jitter” in the spectrum of the last 500MHz than that of the first 500MHz. This is due to the additional influence produced on the spectrum by the extra capacitance introduced from the cable joint as the result of connection, which leads to distortion of the spectrum to some extent.
