Radiated immunity testing verifies a product keeps operating correctly inside a defined RF field — from commercial 3V/m testing to full-aircraft HIRF certification at hundreds of V/m. A complete test setup brings together three distinct product groups on this page.
- Signal generator and power amplifier — the amplifier boosts a swept, modulated signal to the power level needed to reach the target field strength; sizing depends on the field required, antenna gain, and test distance.
- Antenna — radiates the amplified signal toward the EUT. Different antennas cover different frequency bands, so full-range testing typically needs several working together.
- Field probe and chamber — a field probe confirms the actual field strength at the EUT location during calibration, while a semi-anechoic chamber contains the field and protects nearby equipment and people at these power levels.
Military and aerospace testing (GJB151C, DO-160 Section 20) follows the same architecture but extends to higher field strengths and broader frequency coverage, usually requiring multiple amplifier bands to cover the full range in one system.
