The scaleable amplifier/ chamber dilemma solved

Did you know that amplifiers for reverberation testing chambers can be scaleable? Picking the proper amplifier is a major factor in the total costs of a new chamber. That is one of the reasons we teamed up with Rohde & Schwarz, the global market leader in EMC and immunity test solutions, including solid-state RF Microwave amplifiers in various frequency bands/bandwidth combinations and power classes.

Their EMC Solution Specialist in Denmark, Martin Randrup Villadsen, explains the benefits of our cooperation for clients. “All information Comtest feeds us in the design phase helps us predict and calculate a suitable amplifier. They are very accurate in their designs, which makes Rohde & Schwarz more competitive in our price proposals.”

Dimitrios Barakos, Reverberation Specialist at Comtest Engineering, confirms: “When you buy a chamber for a specific test, you need to know the range. For reverberation, the definition of the electric field is important. Sometimes, a more expensive chamber than the competition offers could save much money on the amplifier price. These elements, room and amplifier, influence each other in performance and price.”

Martin: “Clients should also try to think scaleable for future use. I know it’s complicated sometimes, but thinking ahead might save you the burden of building a higher room or replacing your amplifier. Some companies offer confusing ‘upgrades’ where they replace the amplifier with a new one at a discount. We have developed amplifiers with flexible modules, which can be truly upgraded. Nobody likes extra costs, so it’s better to think long-term, and together with Comtest, we can help you with that.”

In the photo, an example of an excellent combination for radiated immunity is the R&S®BBA300 Broadband amplifier, which provides linear high power over ultra-wide frequency ranges, combined with the Comtest Z-fold stirrer for our LUF-200.

How can telecom companies cope with PIM?

PIM has been highlighted as a growing problem for cellular network providers and associated equipment suppliers. This type of interference can reduce receiver sensitivity and, in some cases, may even completely inhibit communication.

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.
