Electrical Properties
Electromagnetic compatibility testing helps us to know
to what degree a material is conductive, resistive, or
insulating (nonconductive). Southwest Research Institute
(SwRI) evaluates the electrical properties, shielding
effectiveness, transmission loss, and reflection
coefficients of materials for frequencies as high as
20 GHz. Active circuits and passive circuits – in whole
buildings, enclosures, and systems – are tested
according to:
MIL-STD-285 NSA 65-6 MIL-R-770B ASTM D 3380 ASTM D 1531
On-Site ConsultationRapid-response consultations can be provided, and technical support for specific, on-site evaluations ranging from short tests to long-term projects requiring
more extensive testing is also available to you. No test is too short or too long. SwRI has the diagnostic test equipment needed for fast, accurate, and cost-effective solutions to most of your EMC-related problems. With this expertise, Institute engineers can identify and
remedy noncompliant conditions while at your facility.
Training
Even though your company may have trained and skilled engineers, they may not have a knowledge of EMC. If they do, it may be out of date or erroneous. SwRI offers classroom
and laboratory training covering many aspects of EMC technology, either at SwRI or at your facility. Subjects include design, analyses, maintenance, test methodology, and standards interpretation.
SwRI will also assist architects and engineers in developing appropriate shielding, sensitive compartmented information facilities (SCIF), and RED/BLACK installations.
Systems Support
Complex systems and subsystems often require a
multidisciplinary approach to testing. SwRI tests and evaluates systems for EMC, environmental, and other
performance parameters, including MIL-STD-810, MIL-STD-461, MIL-STD-462, and FAA/RTCA DO-160. Additional multidisciplinary guidance and support are available from many of the SwRI technology groups, including:
Environmental services Automotive (dynamometers, transmission test stands, whole-vehicle testing) Avionics Medical/bioengineering Space systems Geolocation/radio direction finding
Environmental ServicesIn addition to providing EMC services,
SwRI simulates environments to pinpoint and solve operational problems. Environmental conditions that are
impossible to otherwise recreate, such as earthquakes, can be simulated to determine their effects on systems and components. SwRI's range of environmental simulation services includes:
Simulation of in-service vibration loading Seismic simulations using SwRI- or client-defined earthquake inputs Simulation of natural environments System dynamic response characterization Vibroacoustic system simulation services Validation of analysis scenarios from model data Validation of telecommunications equipment according to specific standards, for example, Telcordia TR-NWT-000063, Issue 4 NEBS.
The Electromagnetic Compatibility Research (EMCR) Section of SwRI is accredited for ISO/IEC 17025, "General Requirements for the Competence of Calibration and Testing Laboratories" for EMC
analyses, design, and testing.
