Uncontrolled emissions compromise life-critical receivers long before specific absorption rate (SAR) thresholds become relevant. A disciplined RF exposure testing lab therefore treats spectral hygiene as the primary safety gate. MiCOM Labs validates radiated and conducted limits in-house and can fold accredited partner SAR data into the same dossier when exposure evidence is mandatory, and releases a single conformity file ready for FCC, VCCI, KS, and RED submission.

Why Choose MiCOM Labs® for RF Exposure Testing

ISO 17025 Chamber Coverage

MiCOM’s semi-anechoic and open-area sites are accredited from 30 MHz through 220 GHz, so a single radiated or conducted sweep satisfies FCC Part 15, CISPR 32, VCCI, and KS KN32 without secondary distance-correlation curves. Using one universally accepted data set eliminates duplicate scans and shrinks multi-market debug loops, especially when schedule pressure peaks near release.

Automated Notified-Body Decision Pipeline

The ISO 17065 Notified-Body Assessment team can review MiTest® raw files the moment a scan finishes, because results flow directly into the secure MiPassport® workspace. Physical location stops mattering; certificates for RED Annex III and UKCA Schedule 3 often issue within ten working days because no hardware or paperwork travels between sites.

MiTest® Real-Time Measurement Automation

MiTest orchestrates antenna sweeps, detector changes, and worst-case EUT mode cycling, then overlays traces on the active limit line while the dwell runs. Engineers see any over-limit harmonic in seconds, make firmware or shielding tweaks before the sample leaves the chamber, and avoid the cost and delay of a second booking slot.

MiPassport® Unified Compliance Workspace

Instead of juggling regional templates, teams upload schematics, BOM, and block diagrams once; MiPassport repackages the material for FCC CB, EU Technical Documentation, KC files, and VCCI confirmation reports. Automated deadline alerts flag expiring grants, so compliance upkeep becomes a routine calendar task rather than a last-minute scramble that stalls shipments.

Global expertise without Freight Delays

Lab engineers can quickly pull up tasks and reports from their California, Shenzhen, and Bangalore offices and work from the same cloud-resident MiTest and MiPassport data sets. Test protocols, device specifics and interim reports never leave the secure portal, which means advice remains consistent worldwide and progress is not slowed by shipping hardware across time zones for review.

Audit-Ready Data Stewardship

MiCOM archives raw captures, calibration certificates, and site-uncertainty budgets for ten years, matching VCCI and EU surveillance windows. When an authority requests evidence, the full chain of custody is retrieved within four hours, preventing shipment holds from snowballing into stock-outs and preserving launch momentum for follow-on models.

RF Exposure Testing Best Practices

Switching-regulator ripple dominates the 150 kHz–2 MHz conducted window
Issue Solution
Uncoordinated converter clocks stack harmonics until the average detector trace drifts within a few decibels of the limit line. Lock all switchers to a common frequency band and give every rail a modest π-filter footprint on the PCB so layout teams can insert attenuation without a board respin if margin disappears during pre-scan.
High-band Wi-Fi traffic produces low-band mixing products

Issue Solution
6 GHz frames can interact with internal reference clocks and land a spur in the aviation DME band or other protected channels. During system bring-up, test with worst-case channel bandwidth and simultaneous high data throughput, then hard-gate firmware to that profile once emissions are verified below limits.
Spread-spectrum clocking disabled late in firmware freeze

Issue Solution
Production images sometimes ship with SSC off to simplify timing closure, moving third harmonics directly onto a limit-line crest. Embed a firmware compliance flag that must report “SSC-enabled” before the lab releases its final report, ensuring harmonic spreading survives code-freeze pressure.
Power-over-Ethernet cabling radiates strong common-mode noise
Issue Solution
Long runs of untuned PoE pairs can act as efficient antennas between 30 MHz and 300 MHz, especially when shield termination is an afterthought. Balance the pair routing early, reserve space for a common-mode choke at the magnetics, and plan for 360-degree shield termination at the enclosure wall so hardware teams are not forced into a last-minute ferrite hunt.
Display boost converters spike radiated bins around 60–100 MHz
Issue Solution
Fast edge rates on OLED or LCD boost stages couple into flex cables and bezel seams, driving a narrow-band peak that escapes initial design reviews. Place the converter inside an RF gasketed zone, route the switch node over a continuous return, and leave PCB keep-out space for a small RC snubber so engineering can damp the edge if chamber data show a surprise peak.

Frequently Asked Questions

Which safety standards do your chambers natively support?

Our lab supports FCC Part 15/B/C, CISPR 32 Class A/B, KS KN32, VCCI Class B radiated and conducted emissions testing, plus radiated immunity for pre-compliance debugging.

MiTest® produces delta-plots in seconds; engineering receives recommended filter or shielding tweaks and a slot for immediate retest.

We can retain raw data up to ten years after the last manufacture date in MiPassport®, which aligns with VCCI and EU surveillance requirements.

SAR and APD are executed by ISO 17025-accredite partners. MiCOM embeds the data and signs the composite RED or FCC technical construction file for submission and/or retention.

No. MiCOM supplies the Notified-Body certificate; you or a third-party agent maintain EU REP responsibility.

Choose the International RF Exposure Testing Partner

Spectral safety sits at the intersection of disciplined emissions engineering, meticulous documentation, and, when mandated, exposure validation. MiCOM Labs delivers all three under one project code so RF projects clear global regulators without collateral schedule risk.
