Pre-Compliance, Debug & Case Studies
A bench RI workflow with a probe/antenna and amplifier, a susceptible-band decision aid, and worked case studies.
Module progress0%
A signal generator + power amplifier driving a small antenna or near-field injection probe lets you find susceptible bands on the bench (relative, not calibrated). Always use the 80% AM modulation. The loop mirrors the Pre-Compliance methodology: illuminate → find the failing band/victim → apply one fix → re-test → step up for margin.
Safety. RF power can cause burns and interfere with other
equipment — contain it (shielded enclosure/tent), respect exposure limits,
and keep emissions legal.
Pick the observed RI symptom for the first fix to try.
Pick a case to see the symptom, the path, and the fix.
Course complete. You can now interpret an IEC 61000-4-3 test,
localize susceptible bands and victims, and harden inputs, cables, grounding and
firmware — the immunity mirror of the
Radiated Emissions course.
