Fast End-to-end Channel Electrical Characterization Methodology for Design and Manufacture Quality Check

This end-to-end methodology from the transmitter, channel to the receiver, is proposed and established for fast, robustness, and accurate PCB characterization to validate design and manufacture quality. The advanced de-embedding with 2x-Thru is adopted to remove the probing effect effectively. Meanwhile, the measurement robustness is validated by intensive repeatability and reproducibility experiments. Through this proposed approach, designers can identify the critical design issues symmetrically and improve the product quality on early design phase by efficient channel loss and system impedance verification.
