EMI/EMC Testing Overview

Contact DTB to learn more about our EMI/EMC testing services – including our TEMPEST testing services.

EMI/EMC testing can reliably predict product performance in any electromagnetic environment. Testing can also determine the possibility of interference with other equipment, possibly degrading performance. Testing may be required in order to comply with regulations or for informational and product improvement purposes.

Electromagnetic interference (EMI) testing ensures that your product will perform properly when subject to the electromagnetic environment in which it is expected to operate. Electromagnetic compatibility (EMC) testing requires appropriate electrical and structural design, equipment installation, wiring installation, and equipment qualification to meet its intended environment.

Dayton T. Brown, Inc.’s experienced staff of electrical engineers and technicians can help bring your project to completion in a timely, low-cost manner.
