ABSTRACT:
A method is provided for measuring insertion loss in cables. The method comprises the steps of measuring a first insertion loss IL12of a first circuit path including the series connection of a first cable and a second cable, measuring a second insertion loss IL23of a second circuit path including the series connection of the second cable and a third cable, measuring a third insertion loss IL13of a third circuit path including the series connection of the first cable and the third cable, and calculating an insertion loss of three or more cables using the formulas:IL1=IL12-IL23+IL132IL3=IL13-IL1IL2=IL23-IL3ILn=IL3⁢n-IL3Where n is the number of cables to be tested.
