Electromagnetic Effects Testing

Product Specifications

L3Harris is equipped to perform electromagnetic environmental effects (E3) testing to meet our customer needs while accommodating government, military (all branches) and commercial aircraft specifications. Our engineers located in Greenville, Texas are experienced in E3/TEMPEST design and testing of aircrafts units and systems with certifications that include NARTE Electromagnetic Control Engineer and NSA TEMPEST Engineer. L3Harris meets customer requirements by conducting electromagnetic effects design and electromagnetic interference (EMI) screen room testing to RTCA DO-160 and MIL STD 461 which provides system level risk mitigation as well as aircraft FAA supplemental type certification (STC) approvals.
