The 2x-thru, the most common standard used for creating fixture models, is never identical to the Fixture-DUT-Fixture due to printed circuit board (PCB) process variation. This difference leads to de-embedding error in the frequency and time domain. This paper introduces a method of impedance corrected de-embedding and its associated advantages. Impedance corrected de-embedding removes the error from differences between the Fixture-DUT-Fixture and reference 2x-thru impedance by implementing a peeling process. Further, the method is inherently more robust, because the fixture manufacturing tolerances do not impact the de-embedding results.
