aerospace EMC

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.

Lightning currents flowing through an aircraft can couple into wiring in multiple ways, from magnetic‑field induction to capacitive coupling across seams, apertures, and composite structures. Part 2 explores how airframe materials, openings, and cable shielding affect the waveforms and levels imposed on onboard systems.

Lightning poses a constant threat to modern aircraft, striking airframes far more often than most people realize. This overview explores early research, lightning‑strike behavior, current waveforms, attachment zones, and the structural factors that influence induced currents inside today’s increasingly complex aircraft.

Current conducted‑emissions measurement practices under DO‑160 and CISPR 25 rely on shielded‑enclosure testing, LISNs, and current probes to evaluate RF noise on power lines. This overview walks through setups, limits, and real measurement results for both aerospace and automotive environments.

Three million years ago, Homo Naledi may have gazed at stars seeking answers. Decades ago, the COBE satellite measured echoes of the Big Bang. One question endures across time: how did this all start? A journey from ancient cosmology to space-age EMC.
