Full Spectrum Testing from DC to 26 GHz
We provide comprehensive EMI/RFI environmental testing to minimize impact on electronic equipment, telemetry & diagnostic systems, communication systems, computers & CRT monitors, servers and IT networks, scientific research instruments, etc. It is important to perform an assessment if the following pertain to your facility:
Our engineers and trained technicians maintain a high standard of quality assurance during the performance of physical testing projects recording EMI and RFI data in Research, Hospital, Industrial and Commercial Facilities.

Full-spectrum DC (0 Hz) to 26 GHz professional electric and magnetic fields (EMF) testing services of new construction sites and existing buildings, will reveal the impact of electromagnetic (EMI) and radiofrequency (RF) interference on equipment, imaging systems, and ensure conformity to various IEC/EN, FCC, and human exposure standards. We test non-ionizing frequencies up to 26 GHz:
Electric and magnetic field site surveys of a device, building or site (future or existing) are selected by EMF emission sources and required bandwidth:
International EMC standards (limited version):
Military compliance standards & requirements:
HEMP/EMP performance in compliance with the standards:
Vitatech provides product emission testing on various electromechanical and lighting systems. These systems include: fan filter units and motors, variable frequency drives (VFDs), LED, fluorescent, and incandescent lighting systems.
We can evaluate the building grounding plans and identify potential ground loops that can generate elevated and high magnetic fields emissions in new buildings. Alternatively, as the electrical infrastructure will degrade in older buildings or due to N.E.C violations (i.e., grounded neutrals, wiring errors, etc.), Vitatech suggests mapped magnetic field site surveys in the building to identity the elevated levels and areas requiring ground/net current remediation.

RF interference assessment is a requirement for:
See standards below:
Epoxy coated rebar testing is performed to evaluate and assess the continuity (resistance) in ohms between adjacent epoxy coated steel rebar members and uncoated rebar sections. This service is highly recommended for NMR, MRI and electron imaging facilities during pre-construction to ensure minimal ground/net current magnetic fields directly beneath EMI sensitive research tools.
For shield performance and verification testing, we use a high current and high magnetic field (1 mG up to 4,000 mG RMS) 3 phase copper bus test to expose the shielding to the predicted or simulated magnetic field environment.
People are typically exposed to very high 50/60-Hz magnetic field levels ranging between 10-1,000 mG (milligauss) when their offices and apartments are next to, over or under transformer vaults, network protectors, secondary feeders, switchgears, distribution busways and/or electrical rooms. Usually employees and tenants are not aware of this potential hazard unless the magnetic field source compromises audio/video equipment, electronic instruments, magnetic storage media, VDT’s, computers, and networks. Once detected it ultimately becomes the responsibility of the building owner/manager to remedy, otherwise the employee and/or tenant may seek legal action. Unfortunately, there are only three practical solutions to mitigate magnetic field exposure produced from electrical systems within buildings: move the victims (people and equipment) away from the source, shield the source or shield the victims from the source.
EMF human exposure/risk assessment standards for government and military personnel, contractors, and visitors based upon: ACGHI, NCRP, IRPA/ICNRP, OSHA, WHO, DOD, and the FCC OET Bulletin 65 Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields.
Vitatech is pleased to introduce vibration and acoustic measurements to our industry leading EMI/RFI surveys. These new capabilities allow us to provide comprehensive site analysis, both pre and post development, for the Semiconductor, Nanotech and CryoEM markets. Vitatech is using the best industry standard equipment and processes to produce vibration and acoustic reports that can stand alone or be utilized by other consultants.
Most equipment that is sensitive to magnetic fields is also sensitive to noise and vibration. Multi-sensitive equipment examples are E-beam, CD-SEM, STEM and FIB tools in the semiconductor industry; MRI, Cryo-TEM in the medical field and most especially research tools like NMR, SEM, EPMA, and Aberration Corrected STEM/TEM. These tools universally have complex site requirements that demand precise and detailed planning.
Combining surveys for EMI, acoustics and vibration can streamline development, especially at the site selection and preparation phases of a project. Timely, comprehensive and accurate information allows more definitive selection of strategies. The result is better decisions made with a high degree of confidence.
