Project brief
Comprehensive Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) test report for an avionics Line Replaceable Unit, covering emissions and susceptibility tests per RTCA DO-160G "Environmental Conditions and Test Procedures for Airborne Equipment" and MIL-STD-461G. The report documents 11 test sections including conducted and radiated emissions, and conducted and radiated susceptibility.
The record describes an EMC evidence package. Explanatory figures show the reporting workflow rather than fabricated receiver traces or test certificates.
The engineering challenge
Make emissions and susceptibility evidence understandable across test methods, uncertainty, and corrective changes.
Engineering approach
- Organize measurements by test configuration and requirement family.
- Record uncertainty and compare pre-compliance and final test context.
- Connect observed issues to shielding, filtering, or layout mitigations.
Features & capabilities
- CE101/CE102 Conducted Emissions: power and signal leads, 30Hz–10MHz
- RE101/RE102 Radiated Emissions: magnetic field and electric field, 30Hz–18GHz
- CS101/CS114 Conducted Susceptibility: power lead ripple, bulk current injection
- RS103 Radiated Susceptibility: 2MHz–40GHz electric field test
- DO-160G Sections 17, 18, 19, 20, 21, 22 corresponding sections
- Measurement uncertainty analysis per CISPR 16-4-2
- Pre-compliance vs final compliance delta analysis and risk assessment
- Mitigation measures: shielding, filtering, layout changes documented
