How to Use Fixture De-embedding to Match Signal Integrity Simulations to Measurements

This video provides a quick overview of how fixture de-embedding from measurements, or embedding into simulations is a critical step for matching simulations to measurements for physical layer Tx to Rx channels. Multigigabit channels that include multi-layer laminate or printed circuit board structures require a fixture to go from the coaxial connections of the measuring instrument to the planar transmission line structures on a PCB. This fixture is not calibrated out by the coaxial calibration of the instrument, and is often neglected in the simulation.
