EMI/EMC Academy 10 Modules Interactive

Radiated Emissions (RE) Testing
Fundamentals for EMI/EMC Engineers

A complete Radiated Emissions curriculum — electromagnetic fundamentals, emission sources, test methods and environments, the FCC/CISPR/IEC/MIL-STD/DO-160 standards landscape, product-category requirements, measurement procedure, detector types, troubleshooting methodology, and PCB design techniques to reduce RE — closing with a real-world 300 MHz failure case study.

Complete these 10 modules in order. Each builds on the previous.

01
Introduction & What Are Radiated Emissions
Why RE testing is legally mandatory, and how unintentional electromagnetic energy escapes through cables, traces, and enclosures.
Lesson~30 min
02
EM Spectrum & Why RE Testing Matters
The 9 kHz–40 GHz spectrum used in RE testing, and the business and technical reasons EMC compliance can't be skipped.
Lesson~30 min
03
Sources of Radiated Emissions
Digital, power, mechanical, PCB, and cable sources — and why cables are often the dominant radiator on an otherwise clean board.
Lesson~30 min
04
Types of RE Testing
Standard, high-frequency, magnetic-field, and electric-field emission tests, plus OATS, semi-anechoic, and fully anechoic test environments.
Lesson~35 min
05
Frequency Ranges & RE Standards
FCC Part 15, CISPR 11/14/15/25/32, IEC 60601-1-2, MIL-STD-461, and RTCA DO-160 — which standard applies to which product.
Lesson~40 min
06
RE Requirements by Product Category
Consumer, medical, industrial, automotive, aerospace, military, and telecom — applicable standards and frequency ranges for each.
Lesson~35 min
07
Test Environment & Equipment
Shielded test facilities, EUT placement and rotation, and the receiver, antenna, and calibration equipment used in an RE test.
Lesson~30 min
08
Test Setup, Measurement & Detectors
Step-by-step measurement procedure, Peak/Quasi-Peak/Average/RMS detectors, and how test distance (1 m/3 m/10 m) is selected.
Lesson~40 min
09
Failure Mechanisms, Design & Troubleshooting
Common RE failure root causes, PCB/cable design techniques to reduce emissions, and a structured troubleshooting methodology.
Lesson~40 min
CS
Case Study, Best Practices & Summary
A real 300 MHz / 8 dB-over-limit failure — root cause, fix, and 6 dB compliance margin — plus a full best-practices checklist and course summary.
Case Study~30 min
CS
Additional Case Studies (FPGA, Power Supply & More)
16 real-world RE failures across FPGA interfaces, switch-mode power supplies, motor drives, and cable/connector issues — pick any one from a dropdown to see its failure graph, debug approach, and fix.
Case Study Library~45 min
