Gigahertz Solutions NFA-1000
Three-axis magnetic and electric field analysis with long-term data logging for overnight bedroom studies.
Methodology
Our Process & Equipment
Repeatable, documented methodology using calibrated, lab-grade instruments — so your readings mean something and can be re-verified after remediation.
The six-step assessment
- 01
Pre-visit intake
You share the address, square footage and your primary concerns. We review tower registries, transmission corridors and utility infrastructure around the property before we arrive.
- 02
Exterior walk-around
Perimeter RF sweep with a directional antenna, powerline and transformer distance mapping, and smart meter measurement at the wall and at the nearest interior room.
- 03
Room-by-room survey
Every occupied room is measured for all four categories, with extended dwell time in bedrooms, home offices and children's rooms where exposure hours are highest.
- 04
Source tracing
Elevated readings are traced to a specific circuit, device or external transmitter — not left as an unexplained number on a page.
- 05
On-site debrief
Before we leave, you see the readings, understand what they mean against Building Biology guidance, and get the immediate no-cost changes you can make today.
- 06
Written remediation report
Within 48 hours: annotated measurements, photographs, guideline comparisons, and a prioritized action plan ranked by cost and impact. Vendor-neutral, always.
Instruments we use
Gigahertz Solutions HFE-59B
Directional RF measurement to 8 GHz with peak-hold and audio demodulation to identify each transmitter type.
AlphaLab TriField & Gaussmeter
Calibrated broadband magnetic and electric field verification and rapid room screening.
Stetzer & Greenwave line meters
Dirty electricity measurement from 2 kHz to 100 kHz at individual outlets and circuits.
Body voltage test kit
Quantifies the electric field actually coupling to an occupant in bed, not just the ambient room value.
Annual NIST-traceable calibration
Every meter is calibrated on the manufacturer's schedule; calibration dates are printed in your report.
Guidelines we report against
Every reading in your report is shown next to the Building Biology SBM-2015 sleeping-area benchmark as well as the FCC and ICNIRP limits, so you can see the full context rather than a single verdict.
| Field type | Target value | Reference |
|---|---|---|
| Magnetic (60 Hz) | < 0.2 mG in sleeping areas | SBM-2015 'no concern' |
| Radio frequency | < 0.1 µW/m² in sleeping areas | SBM-2015 'no concern' |
| Electric field | < 1 V/m body voltage equivalent | SBM-2015 'no concern' |
| Dirty electricity | < 50 GS units per circuit | Common practice threshold |
