immunity testing

Rohde & Schwarz expands the R&S BBA300 broadband amplifier family with new 500 W and 1000 W models covering 1–6 GHz in single-band operation. Designed for automotive, aerospace, and defense EMC testing — including HIRF applications — the solid-state units offer high linearity, mismatch tolerance, and modular system integration.

Learn the essentials of EMC troubleshooting for product designers with this introductory column from Kenneth Wyatt. It explains why EMC failures derail product launches, highlights core design challenges, and offers foundational resources to help engineers start diagnosing emissions and immunity issues directly on the bench.

Changing enclosures, PCB layouts, component sources, or software doesn't mean the schematic changed—but it may mean your EMC certification did. This installment of Standards Practice breaks down which hardware modifications trigger the need for retesting, and why skipping it can be a costly mistake.

Behind every successful EMC compliance test is a high-quality RF amplifier. Learn how these devices generate required field strengths, suppress unwanted harmonics, and maintain stable operation during demanding radiated immunity testing in semi-anechoic chambers.

When traditional EMC troubleshooting tools fall short, the reciprocity theorem can reveal hidden immunity problems. This real‑world case study shows how unexpected RF sources—like walkie‑talkies—can expose susceptibility paths, helping engineers diagnose failures and strengthen designs with simple, effective fixes.
