Following best design practices for controlling EMI will increase your chance of success in your next design. But, sometimes knowing what not to do is just as important. Read on to get some advice from Todd Hubing as recounted by SIJ technical editor, Eric Bogatin.
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.
This eGuide guide shows how to make accurate power rail measurements and how impedance measurements can help to detect typical root causes of power integrity issues.

Spectrum Instrumentation extends its range of hybridNETBOX products with the addition of eight high-performance models. The hybridNETBOX is an advanced instrumentation platform that combines a multi-channel arbitrary waveform generator (AWG) and a digitizer in a single portable unit.
This SI/PI Technical Session presented by Steve Sandler, available On-Demand, will address how a simple design workflow could result in more cost-effective designs with fewer expensive board spins. The proposed workflow would also reduce the effort expended by semiconductor companies in developing simulation models. The result is a unified, end-to-end model, providing power rail noise, spectral content, EMI, dynamic transient response and power rail impedance all within a single model.
