Techniques to Characterize Signal-Integrity Problems Quickly and Accurately
Posted @ 11/10/2015 7:29 AM
In today’s high-speed digital designs, signal-integrity issues such as reflections, excessive losses, and crosstalk can degrade system performance. There are techniques through the use of time-domain reflection (TDR) and transmission (TDT) in both simulations and measurements that help engineers characterize and troubleshoot signal-integrity issues with greater measurement accuracy.

This article discusses three techniques that can help characterize and troubleshoot signal-integrity issues:
- performing TDR/TDT simulations,
- utilizing true short open load through (SOLT) calibration, and
- automatic fixture removal (AFR) for simple and accurate error correction.
