Reverberation Chamber Workshop

Reverberation Chamber Workshop

Sponsored by ETS-Lindgren and NTS Plano

Thursday, November 10, 2016, 12:30pm - 6:00pm | NTS Plano

NTS's second reverberation chamber workshop will take place at our Plano, Texas facility on Thursday, November 10, 2016*. Sponsored by ETS-Lindgren and NTS Plano, this is a free, hands-on, half-day workshop open to those that are interested in learning about reverberation chamber test methodology including new applications for this versatile and robust test environment.

Reserve your seat today - space is limited!
This is a free event; please register by November 8th to ensure adequate seating and catering.

*The first reverberation chamber workshop was held at our Fullerton, California facility on October 17, 2016.

Technical Program


Once mainly used for Government test requirements, the reverberation chamber is increasingly being used for aerospace, automotive, and consumer electronic test applications due to its inherent efficiencies in cost and time. In addition to providing practical, application oriented material that you can use on the job, the workshop includes a live demonstration of a EUT using the reverb chamber at NTS Plano.


  • Overview
    Reverberation chamber testing and common uses today, statistics with references to additional information for those who want to dig deeper, and applicable standards.
  • Test Set-ups
    Per the most common standards, including MIL-STD-461 and DO-160, you will learn what is common, what is different, which one is more accurate, and if the same chamber can be used for both.
  • Monitoring the Test Chamber
    A review of the basics during a reverberation test such as forward amplifier power, E-field sensor levels, field uniformity, number of test frequencies chosen, number of paddle positions, and frequency scan rates. Additionally, the intricacies of what to be on the look-out for ensuring a valid test.
  • Test Validation
    Review of success criteria including a checklist of MUST have items
  • Pros and Cons of Reverb Testing (versus a typical RS103 or semi-anechoic chamber based test) You will learn what NOT to test in a reverb chamber (i.e. why a semi-anechoic chamber may be a preferred test environment), what works well for testing in a reverb chamber based on the EUT and desired test objectives, as well as recommendations for the optimal test environment based on time, cost, space available and the test objective

Reverberation Demo

The reverberation chamber is an effective tool for performing Immunity, Emission and Shielding Effectiveness measurements on a wide range of DUT types. It has become especially popular for performing high field strength immunity tests on large and complex components, systems and vehicles.

Demo features:

  • Key setup attributes and performance advantages of a reverb chamber
  • Abbreviated immunity test demonstrating the key fundamental differences between the mode tuned and mode stirred test methods currently used in defense, aerospace, and automotive industry testing
  • Look at the effectiveness of coupling into a leaky RF cable assembly (time permitting)


About the Speakers

Garth D'Abreu

Director Automotive Solutions
ETS-Lindgren | Cedar Park, Texas

Due to his considerable industry experience, Garth is the ETS-Lindgren global subject matter expert responsible for the on-going research and development of Automotive EMC/Wireless test chambers for Regular, Electric and Hybrid Electric Vehicles. His primary responsibility is the design and development functions within the Systems Engineering group, the group that a) provides worldwide technical support for ETS-Lindgren and b) is directly responsible for anechoic chamber, E- Field generator, TEM device and instrumentation system design and development.

As the lead engineer for reverberation chamber design and test, Garth is also responsible for the development of GTEM cells, EMP protection applications, and wireless device test systems. Additionally, he also provides technical support to the RF filter department, is a member of the IEEE EMC Society, and is an active participant in standards development including:

  • IEC, SAE, ISO, and CISPR D automotive EMC standards
  • MIL-STD-461, RS103
  • DO-160 military/aerospace EMC standards

Garth has over 30 years of experience in the RF industry and holds a BSc degree in Electronics and Communications Engineering, from North London University, UK.

Interesting Fact

Garth started his career in reverberation chambers in the 1980s working with industry luminaries including Mike Hatfield with the US Navy in Dahlgren, Virginia. The collaboration between Garth and Mike resulted in the first IEC standards (IEC-61000-4-21) being based off of reverberation chamber test methodology.
