Worry-free testing,
wherever you want.

At our family-owned factory, we’ve harnessed our expertise in maximizing limited space to create a compact reverberation chamber with a lowest usable frequency (LUF) of 1GHz. This chamber, designed to meet EN61000-4-21/RTCA-DO160G criteria, is a testament to our commitment to quality.

We’ve made it even easier for you with a plug-and-play setup, including antennas and RF cables. All you need to do is find a socket to power it up, and you’re ready for worry-free testing.

Lowest Usable Frequency (LUF) 1000

A reverberation chamber is a specialised EMC test chamber generating very high field strengths using modest amplifier power. The reflections between the RF-shielded walls are optimised to add up to a maximum of as many standing waves as possible.
A reverberation chamber is mainly used to test the electrical immunity of test objects (EUT) but can also be used to test total radiated emissions, radiated power, material analysis, and shielding effectiveness (nested method). Radiated susceptibility testing in a reverberation chamber is faster and more realistic compared to testing in a semi-anechoic chamber. The LUF 1000 has a lowest usable frequency of 1000MHz and complies with the IEC61000-4-21 and RTCA-DO160G EMC standards.

Happy clients

Test execution very close to real-life

“Comtest is extremely flexible, forward-thinking and fast.
We are satisfied with our EMC chamber, which is set up to
provide us with load possibilities far beyond anything possible
with third-party testing solutions. This makes our test execution
very close to real-life usage of our products.”

Tim Flintholm Fink
Director of Test, Validation and Engineering Support

Essential to ensure reliable testing

“NXP is located on the High-Tech campus in Eindhoven.
Here the electromagnetic spectrum is quite crowded.
Shielded rooms are essential to ensure reliable testing.
Our 3 Comtest RF-shielded facilities have never sat empty,
which speaks volumes regarding their value to us.”

Hans Schmitz
Lab manager

Clear and candor way

“The clear and candor way Comtest
communicates, made it easy to
effectively determine the scope of
the project.”

 

Rob Kleihorst
System Designer and EMC Lead, Image Guided Therapy

No risk of incompatibility

“Comtest delivers a turn-key solution,
so there’s no risk of incompatibility or
subpar calibration.”

Omar Romero
Engineer

Extremely motivated

“The Comtest team was extremely motivated
to create a unique type of chamber system that
hasn’t been built before.”

Dr.-Ing. Hanno Frömming
Managing Director

Reputation for quality

“For the expansion of our testing capabilities we worked
with Comtest for the construction of a new,
oversized testing chamber. We chose to work with Comtest
based on their reputation for quality and the fact
that they’re a Dutch company.”

Chiel Spithout
Senior Engineer

Works very fast and thoroughly

“At Emitech, there are over 40 different types of testing
chambers to fit any testing. Comtest has built many of them
and works very fast and thoroughly. They completed our 
latest
3M SAC setup within one week
We look forward to working
with Comtest on future projects.”

Our services include maintenance and validated testing. We recommend that both are executed by authorized personnel only. Our expert teams can perform preventive maintenance on RF-shielded doors, mode-stirrer systems, and positioning equipment such as turntables. We also offer validation services to see if your EMC test chamber or RF-shielded room still functions within its intended limits and avoiding unexpected down-time or product recalls at the same time.

A shielded room can perform conducted emission and immunity EMC measurements, eliminating harmful external influences, leading to more accurate and consistent test results. Being a Faraday cage, a shielded room will not only improve test results but will also form an excellent aid in protecting information and essential hardware. Comtest can assist governments, the military, financial institutions, and large corporations in protecting what matters most in critical situations. We offer the highest quality, sensitivity, and security before, during and after working with you.
