Radiated Immunity Test Systems

Verifying that a device continues operating correctly when exposed to a strong external RF field is the core purpose of radiated immunity testing — reproducing a high-intensity RF field around the device under test and confirming it doesn't malfunction, reset, or degrade under that exposure. This range covers the systems built to generate that field across a wide span of applications and intensity requirements.

Full-aircraft and phased-array HIRF (High-Intensity Radiated Field) systems address the demanding requirement of testing aircraft and large systems against the electromagnetic environment they may encounter in service, including from nearby high-power transmitters. Military and automotive field-strength systems built to GJB151C cover the specific, more stringent immunity requirements those sectors mandate, and turnkey automotive immunity chambers provide a complete, ready-to-use solution for automotive-sector immunity testing specifically.

This spread — from full-aircraft HIRF testing at one end to standard automotive immunity chambers at the other — reflects how differently "radiated immunity testing" scales depending on the device under test, the applicable standard, and the field intensity the application actually needs to demonstrate tolerance against.

Frequently Asked Questions

What does "HIRF" testing specifically evaluate?

High-Intensity Radiated Field testing verifies that aircraft systems continue operating safely when exposed to strong RF fields they might encounter in service — from ground-based transmitters, radar, or other high-power RF sources — a critical certification requirement for aircraft electrical and electronic systems.

Why does automotive immunity testing use GJB151C alongside other automotive standards?

GJB151C is a Chinese military/defence electromagnetic compatibility standard sometimes applied to automotive and military-adjacent equipment requiring more stringent immunity performance than standard commercial automotive EMC standards specify, depending on the vehicle programme's requirements.

What's the difference between a turnkey automotive immunity chamber and a general radiated immunity system?

A turnkey automotive chamber is a complete, purpose-built solution sized and configured specifically for automotive-sector immunity testing, while general radiated immunity systems may need to be configured from separate components (field generation, chamber, control system) depending on the specific application and standard being tested against.
