Techniques to Characterize Signal-Integrity Problems Quickly and Accurately

 

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.

 

MATsolutions' insight:

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.
