A Guide for Single-Ended to Mixed-Mode S-parameter Conversions

Signal integrity engineers almost always have to work with S-parameters. If you have not had to work with them yet, then chances are you will sometime in your career. As speed moves up in the double-digit GB/s regime, many industry standards are moving to serial link-based architectures and are using frequency domain compliance limits based on S-parameter measurements.

Preamplifier Options for Reducing Cable-Braid Loop Error

When measuring low impedance with the two-port shunt-through configuration, we potentially create an error due to the resistance of cable braids.  This error can be reduced or eliminated by using appropriate preamplifiers. There are professional preamplifiers on the market that do a great job reducing the cable braid error.  If you want to experiment with your own circuit, this article will help you
