RTCA/DO-160 TESTING
   
 
Welcome to D.L.S. Electronic Systems, the largest independent commercial Electromagnetic Compatibility and Product Safety compliance testing facility in North America. Centrally located in suburban Chicago, IL, for over 20 years, the engineering staff at D.L.S. has been helping numerous manufacturers and marketers of electronic and electrical equipment meet global regulations and industry compliance needs in a prompt and economical manner. D.L.S. is certified by the US. Department of Commerce, through the National Institute of Standards and Technology (NIST), program of National Voluntary Laboratory Accreditation Program (NVLAP).
 
 
D.L.S. offers one of the most modernly equipped laboratory compliance testing operations in North America, fully accredited by NVLAP, with 6 EMC testing chambers that are specially designed and dedicated to RTCA-DO 160 compliance. We have a staff of 25 engineers, of which 15 are NARTE accredited, making D.L.S. a fully accredited NARTE facility.
 
 
Our unique facility has three oversized EMC testing chambers, with 36 feet by 25 feet by 20 feet dimensions. Our chambers are configured to handle large devices, as well as unusual sized or dimensioned products. We offer state of the art support equipment including separate shielded load rooms, noise controlled annex power rooms, a 120,000 BTU, 10 ton chiller and cooling system, 15,000 cubic feet per minute air intake and airflow capabilities.
 
 
D.L.S. can provide power up to 2000 amps, 480 volts, 400 Hz, three phase, utilizing in-house power generation capabilities. Testing capabilities can provide 200 volts per meter field strength, as well as 600 volts per meter pulse, up to 40 GHz. D.L.S. has over 150 LISN's, custom built antenna, and extra large H Field generators, to handle the unique device requirements.
 
 
D.L.S. offers hands on trouble shooting and design assistance as well. We regularly test products for compliance in a number of categories, such as avionics, instrumentation, communications, passenger entertainment, in-flight galley equipment, flight control and management, navigation, identification, power generation and monitoring, flight data recorders, internal and external telecom equipment, and other aircraft equipment. We also offer environmental testing through our partner lab program, most commercial and military specifications.
 
 
D.L.S. has pioneered a detailed Early Design Evaluation program, a free consultation with experienced EMC and Product Safety engineers, providing a comprehensive design review of your product, prior to scheduled testing. The review can identify subtle flaws in design, ones that can cause costly engineering time if found during testing.
