Shield Your Products from Failure and Interference

Electromagnetic environments can pose significant challenges to your product’s performance. At Dayton T. Brown, Inc., our comprehensive EMI/EMC testing services ensure your products meet regulatory requirements, avoid interference, and perform reliably in their intended environments.

Why EMI/EMC Testing Matters

Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) testing are critical to ensure that your product:

Operates reliably within its electromagnetic environment.

Avoids causing or receiving interference from other devices.

Meets regulatory compliance standards or achieves design optimization.

Our EMI/EMC Testing Solutions

Electromagnetic Interference (EMI) Testing

EMI testing evaluates the potential interference a product may cause within its electromagnetic environment, ensuring that your equipment does not emit harmful electromagnetic radiation that could affect nearby systems. This testing is particularly crucial for military, aerospace, and commercial systems operating in environments with strict electromagnetic standards.

Electromagnetic Compatibility (EMC) Testing

EMC testing ensures that your product can operate without interference from external electromagnetic disturbances and that it does not emit harmful radiation. This is crucial for systems in complex environments like military and aerospace applications, where performance is critical.

RTCA/DO-160 Testing

As part of our EMI/EMC Testing Services, DTB provides specialized RTCA/DO-160 testing to ensure avionics meet rigorous electromagnetic and environmental standards. Our capabilities include emissions and susceptibility testing up to 40 GHz and radiated susceptibility fields exceeding 200 V/m, ensuring reliable performance across all aviation platforms.

TEMPEST Testing

A specialized process for identifying and mitigating information leakage risks through unintentional emanations, such as electrical signals, sounds, and vibrations. We ensure your systems are protected against electromagnetic vulnerabilities, safeguarding sensitive information while meeting the highest security standards.

Positive Train Control (PTC) Testing

DTB provides specialized Positive Train Control (PTC) testing services to ensure railroad systems comply with the Rail Safety Improvement Act of 2008 and Federal Railroad Administration (FRA) regulations. PTC systems are crucial for preventing train collisions, over-speed derailments, and other safety risks.

Electromagnetic Pulse (EMP) Testing

Electromagnetic Pulse (EMP) testing evaluates the resilience of electronic equipment against high-amplitude, short-duration electromagnetic energy pulses caused by events such as the detonation of nuclear devices at high altitudes (HEMP, HAEMP, and HNEMP).

Shielding Effectiveness Testing

DTB provides Shielding Effectiveness Testing to ensure materials and systems meet electromagnetic interference (EMI) standards. With extensive experience, we customize tests for military, commercial, and industrial applications.

Lightning Testing

DTB’s comprehensive lightning testing services evaluate the resilience of your electrical systems and components against lightning-induced transients. We utilize a state-of-the-art simulation test system from HV Technologies to generate a wide range of waveforms, including single-stroke, multi-stroke (MS), and multi-burst (MB) scenarios, in line with national and international aviation standards.

Shipboard Electrical Testing

Our comprehensive shipboard power and magnetic field testing services meet the stringent requirements of military and commercial applications. Our capabilities include testing for DC magnetic field environments and ensuring compliance with necessary power input configurations. We specialize in ungrounded user equipment power, ensuring that your systems are fully compliant with shipboard standards.
