5.7.11 Delta-L 4.0 PCB Characterization
Option R&S ZNB-K231/R&S ZNBT-K231
Delta-L is a de-embedding methodology developed by Intel Corporation and is used for
de-embedding strip lines that include vias. Delta-L calculates the loss of PCB intercon-
nects and can be performed on single-ended or balanced interconnects.
The objective of Delta-L is to determine an insertion loss measurement defined on two
or more coupon lines of differing lengths. This ratio of insertion loss in dB/inch can be
applied to any trace length with similar vias.
