Radiated Immunity Chambers

Full compliance radiated immunity test chamber for products fitting into a square of 1.5m. These measurements are in compliance with the IEC/EN 61000-4-3 standard. Additionally, pre-compliance emission testing can be executed in a very repeatable environment.


Radiated Immunity Chambers

Our compact full anechoic chamber is designed for radiated immunity measurements at a testing distance of 3 meters. In addition to immunity testing, it also provides a very repeatable environment for pre-compliance emissions testing as per CISPR16-1-4. Want to know more about our radiated immunity chambers?

Small size, big features

One of the main benefits of a compact full anechoic chamber is its small size. Thanks to its space saving characteristics, the compact chamber can be installed in almost any building or office while still providing a lot of research and measurement options:

  • Full compliance immunity test site for the frequency range of 80MHz up to 6GHz
  • Stable and uniform environment due to lining with durable polystyrene absorbers
  • Pre-compliance emission measurements at 3m distance

 Perfect for commercial, military and automotive testing

Before a product is either sold or used in commercial or military applications, testing is required to determine whether it complies with radiated emissions and immunity limits. This is especially important for military or aviation purposes where interference or susceptibility to interference is a major concern. Our compact radiated immunity chamber is well suited for this type of testing.

 Why purchase a radiated immunity chamber?

Being able to perform measurements in-house saves a lot of time and money:

  • Lower costs – save money by in-house compliance testing instead of outsourcing at external laboratories.
  • Time saved –  no more time wasted by shipping to and from third party facilities.
  • More accurate testing – your chamber is setup specifically for your research and development needs.
  • Less risk of damage or leaks – keeping a product in house means less risk of damage during transport or potential leaks of information.
  • Faster development – having your own testing facility allows you start testing a product or device after each small change, at any time

Typical performance

The typical performance of our compact radiated immunity chambers are:

  • Field Uniformity (FU): 75% of 16 points ≤6dB at 3m test distance & 1,5 x 1,5m test window (0,8m high)
  • Pre-compliance emission testing:
    • Free Space NSA: Between 30MHz up to 200MHz: ±8dB / 201MHz up to 1000MHz: ±6dB at 3m distance (0,8m diameter test volume)
    • Site VSWR: 1GHz up to 18GHz ≤6dB 3m distance

Relevant test methods are IEC/EN 61000-4-3 and CISPR-16-1-4 (pre-compliance testing only).
