EMC Immunity Testing

Electromagnetic Compatibility (EMC) immunity testing is conducted across automotive, medical, aerospace, industrial, consumer, and communications sectors to verify that electronic systems operate reliably in the presence of electromagnetic interference (EMI). These tests simulate real-world electromagnetic environments to assess product performance, robustness, and compliance with international standards.

During immunity testing, high power RF amplifiers are used to generate controlled electromagnetic fields at defined frequencies and field strengths. These fields are applied to the device under test (DUT) to evaluate susceptibility to radiated and conducted disturbances. Repeatability, field uniformity, and signal integrity are critical to ensure accurate and standards-compliant results.

Typical EMC immunity requirements span frequency ranges from 10 kHz to 18 GHz, extending up to 40 GHz for advanced applications, with continuous wave (CW) and pulsed power levels reaching 10 kW. Test methodologies include radiated susceptibility, conducted immunity, and reverberation or anechoic chamber-based evaluations.

AR RF/Microwave Instrumentation provides a comprehensive range of RF and microwave amplifiers designed specifically for EMC testing applications. These amplifiers support both broadband and band-specific requirements, delivering stable output power, low distortion, and fast response characteristics across the required frequency spectrum.

Available in solid-state and travelling wave tube (TWT) configurations, AR amplifiers are engineered to meet the demands of high field strength generation, pulse fidelity, and continuous operation. Systems can be configured as standalone units or integrated into complete EMC test solutions, including control software, field monitoring, and chamber integration.

For more complex or high-power applications, particularly in defense and aerospace environments, amplifier systems can be customised to meet specific standards, test setups, and facility constraints. This includes multi-band architectures, automated switching, and tailored system integration to support efficient and repeatable test workflows.
