We measure and record electric field strength (V/m) and magnetic field strength (A/m) from various RF sources from 14 kHz – 26 GHz. Including electric field, plane wave, and microwave sources: - RF Sources Include Intentional & Unintentional (spurious): mobile, marine, UHF/VHF, cell/PCS, radar, radio navigation services, government time radio stations, military communication, distributed antenna systems (DAS), etc. - Typical sources include: TV/AM/FM Broadcast transmitters, WiFi Nodes & Cellular Phones - Typical sources include: Variable Frequency Drive (VFD) pumps and motors, fluorescent light ballasts, RFID scanners and/or heat sealers Radio Frequency Interference (RFI), is increasingly an issue for siting sensitive instruments, communications system design and operation, and human RF exposure safety. RF interference assessment is a requirement for: - Sensitive medical devices (e.g. MRI’s, NMR’s, EEG’s, MEG’s) - Sensitive research equipment (e.g. STMs, some AFM’s, certain cryogenic amplifiers, CCD’s, and other applications) - Commercial Grade recording/production studios - Systems employing RFID (e.g. manufacturing, medical) - High-Rise buildings with first-responder/cellular repeaters - Safety Systems – Elevator Controllers, Environmental controls - Dense RF transmitter environments (rooftops, etc.) Evaluation EMF human exposure/risk assessment standards for government and military personnel, contractors, and visitors based upon: ACGHI, NCRP, IRPA/INIRC, OSHA, WHO, DOD, and the FCC OET Bulletin 65 Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields. See standards below: - RF – electric/magnetic field site survey (14 KHz – 26 GHz) - Industrial Scientific & Medical (ISM) RF frequencies E and H field (i.e., heat sealer) compliance site survey (13 MHz, 27 MHz, 40 MHz, 915 MHz, 2.45 GHz, 5.8 GHz and 24 GHz) - FCC OET Bulletin 65 Addition 97-01, Evaluation Compliance with FCC for RF Human Exposure Limits, (300 kHz – 100 GHz)
