EMF & RFI Survey and Testing

Full-spectrum DC, AC ELF, RF EMF Surveys & EMI/RFI EMF Testing

Vitatech Electromagnetics provides specialized, full-spectrum (0 Hz – 300 GHz) electric and magnetic fields (EMF) and electromagnetic compatibility (EMC) EMF consultation services in the areas of test and evaluations to verify shielding performance compliance to IEEE-STD-299 (replaced MIL-STD-285) of a prototype, model, and partial-or fully-enclosed shielding room, building or mobile unit and EMF/EMC standards/policies (MIL-STD & NSA).

Comprehensive Environmental Testing
Vitatech also performs environmental testing (and independent verifications) recording EMF/EMC site survey/measurement data of occupied rooms, buildings and entire sites, evaluates the impact of electromagnetic and radiofrequency (RF) interference (EMI/RFI) on equipment/systems, and ensures conformity to various EMF human exposure standards emanating or radiating from:

  • Static DC EMF sources (geomagnetic, subways, MRIs, NMRs, etc.)
  • AC ELF (extremely low frequency) EMF sources (power lines & equipment)
  • VLF (very low frequency) and LF (low frequency) EMF sources (CRT monitors)
  • RF (radiofrequency) EMF sources (mobile, marine, UHF/VHF, cell/PCS, radar)
  • EMP (electromagnetic pulse) & HEMP (high-altitude electromagnetic pulse)
  • PQ (power quality) electrical sources (harmonics, voltage/current surges, etc.)

Unmatched Quality Assurance
Our engineers and trained technicians maintain the highest standards of quality assurance during the performance of physical testing projects recording EMF/EMC data in the laboratory or in the field, shielding performance testing (IEEE-STD-299), constructing simulations and models, measuring power quality (PQ) characteristics, assessing and evaluating recorded data and producing the final report with ample charts, tables, and 2-D/3-D color graphics, as required.
