EMI / EMC Testing

EMI / EMC Testing Services

Mission-Critical Electromagnetic Compatibility Validation
for Hi-Rel and Defense Systems

AAA Engineering and Test Lab provides electromagnetic interference and electromagnetic compatibility (EMI/EMC) testing to support qualification, certification, and risk reduction for high-reliability electronic systems. Testing is executed for defense, aerospace, space, and mission-critical applications where electromagnetic performance directly impacts safety, functionality, and mission success.

EMI/EMC testing is commonly performed to MIL-STD-461, platform-specific military requirements, DO-160, and other customer-defined specifications. AAA executes customer-defined test plans and focuses on controlled execution, traceable results, and audit-ready reporting to support program reviews, qualification documentation, and anomaly

EMI / EMC Testing Capabilities

All EMI/EMC testing is performed under engineering oversight to ensure controlled setups, repeatable execution, and technically defensible results aligned to program requirements and accreditation scope.

Supported Standards & Accreditation Scope

MIL-STD-461 (A–G) – Execution to customer-defined requirements
MIL-STD-704 – Aircraft electrical power characteristics
MIL-STD-1275 – Vehicle electrical power compatibility
DO-160 Section 20.5 – Radio frequency susceptibility
DEF STAN 59-411 – Electromagnetic compatibility (UK)

Testing is performed by credentialed personnel and aligned to applicable accreditation scope and laboratory controls.

Test Infrastructure and Facilities

Shielded enclosures and screened rooms
Hybrid chambers supporting radiated and conducted testing
High-power RF amplifiers and transient generators
Instrumentation supporting automated and repeatable test execution

Facility configuration and chamber selection are verified during test planning to ensure proper field uniformity, coupling paths, and compliance with method intent.

Key EMI / EMC Test Capabilities

MIL-STD-461 Test Families (Common)

Conducted Emissions (CE)
Conducted Susceptibility (CS)
Radiated Emissions (RE)
Radiated Susceptibility (RS)

Radiated Emissions – Method-Specific Coverage (Typical)

RE101 (Magnetic Field): 30 Hz to 100 kHz
RE102 (Electric Field): 10 kHz to 18 GHz
RE103 (Antenna Spurious and Harmonics): 10 kHz to 40 GHz

Final frequency ranges, limits, and applicability are executed per platform tailoring, program requirements, and approved test plans.

Radiated Susceptibility

RS103: Up to 200 V/m across program-defined frequency ranges (commonly 2 MHz to 40 GHz; down to 10 kHz when required).

Conducted Emissions and Susceptibility

Conducted testing executed per applicable CE and CS methods, including power and signal line evaluation based on platform and system configuration.

Automated Test Execution and Data Integrity

AAA utilizes automated test control and data acquisition tools to support repeatable execution, reduce operator variability, and preserve data integrity. All test activities are documented with traceable instrumentation, configuration records, and controlled reporting workflows to support audit and certification needs.
