Abstract
A method for examining differential pair transmission lines, performed by a processor, comprising: capturing a plurality of first insertion losses of a first signal line within a frequency range and a plurality of second insertion losses of a second signal line within the frequency range, wherein the first signal line and the second signal line are configured to transmit a pair of differential signals; calculating a plurality of maximum error ratios between the first insertion losses and the second insertion losses within the frequency range; determining whether any one of the maximum error ratios is greater than or equal to an upper threshold; outputting a warning signal when the processor determines one of the maximum error ratios is greater than or equal to the upper threshold; and ending the method when the processor determines each one of the maximum error ratios is smaller than the upper threshold.
