Dennis Rollinger, CEO

Dennis Rollinger founded Radiometrics in October of 1983. Dennis along with two partners started the company because they felt that there was a significant need for greater customer support in the commercial Electro-Magnetic Compatibility (EMC) industry. Radiometrics was one of the first laboratories listed in the Federal Communications Commission (FCC) Public Access List (PAL) of labs performing commercial EMC testing. Radiometrics has grown significantly under his direction and Dennis has since become sole proprietor.

In Radiometrics 23-year history, Dennis has been associated with over 5,000 test programs performed to the EMC specifications of the Military, Federal Communications Commission, Federal Aviation Administration, Food and Drug Administration, International Standards Organization, Society of Automotive Engineers and other proprietary test specifications.

Dennis has also been involved in several international military and aerospace programs. Included in these are the testing of systems for the International Space Station, LAVI jet fighter, Saab Scania jet fighter, and the British EH-101 helicopter program.

Over the past five years Dennis has overseen in excess of 200 tests of medical devices.

Dennis has served on numerous industry committees including:

  • Radio Technical Commission for Aeronautics (RTCA), Portable Electronics Devices (PEDS) Committee 166- Established the ruling that all electric carry-on equipment must be turned off and stowed prior to take-off and landing.
  • RTCA, DO160 Standards Committee- Member of the EMC Standards Committee for all electronic equipment used on board commercial and general aviation aircraft.
  • Rehabilitation Engineering Society of North America (RESNA)- Chairman of the Wheelchair EMC committee.
  • Society of Automotive Engineers (SAE) – Developing EMC standards for on and off road vehicles.
  • US Technical Advisor to the International Standards Organization ISO 7176 for Electromagnetic Compatibility issues with powered wheelchairs.
  • Association for the Advancement of Medical Electronics (AAMI)- Member of the EMC Committee developing standards for electronic medical devices.

Before founding Radiometrics Dennis served as a Non Commissioned Officer for the U.S. Army Signal Corp. He was in charge of the Phan Rang Central Communications facility located in Phan Rang, Vietnam. Dennis was honorably discharged in December of 1970.

Dennis received his Degree in Electronics from Morton College in June of 1973. He then worked as a Senior Technical Associate for ten years with AT&T Bell Telephone Laboratories. He was the physical designer and regulatory engineer for the 3B20 computer system designed as the Agency Standard Host Computer for the National Security Agency.

Dennis also holds a commercial pilot’s license with an instrument rating and instructor rating. He is a consultant on the development of new avionics equipment for commercial avionics and for the National Transportation and Safety Board for EMI incidents.

Chris Carlson, Technical Manager

“I control my own destiny here, and that’s important. The company is what we put into it, we all draw our motivation from this.”

Chris Carlson is the Technical Manager at Radiometrics. He is a NARTE certified engineer and handles many of the military and aerospace testing having technical expertise and knowledge in these areas.Chris’s NARTE certification was grandfathered by eminence in the EMC field. “I did not have to take the test but did help write the questions to develop the test for NARTE candidates,”says Chris Carlson.

Chris is competent in designing and constructing specialty tests and test equipment. Chris also writes most of the test software for Radiometrics.

Chris served on the Radio Technical Commission for Aeronautics (RTCA), DO160 Standards Committee. He was a member of the EMC Standards Committee for all electronic equipment used on board commercial and general aviation aircraft.

He became interested in electronics as a kid and entered Rose-Hulman Institute of Technology in Terre Haute , Indiana with ambitions to get an Electrical Engineering Degree. Two-thirds of the students usually change their majors, but Chris maintained his focus and received his Bachelor of Science in Electrical Engineering in 1991 with an emphasis on electromagnetics and field theory.

Chris came to work for Radiometerics in 1984. He states, “This is a very comfortable place to work. There is a family atmosphere, a low stress environment. Everyone knows their job and what needs to be done. Each has a specialty but can be interchangeable as well.”

Radiometrics tailors work to provide solutions effectively and efficiently. “Other companies do cookie cutter test, we modify our test so they are completed to everyone’s satisfaction. This means we work closely with our clients,” states Chris.

Chris feels that the company went through a big change with its A2LA accreditation. “This improved the quality of everything that we do, well beyond what we expected to find,” says Chris.
