Field Uniformity Testing Services – Precision for EMC Compliance
BQuest Labs, aISO 17025 NABL-accreditedlaboratory for EMCchamber calibration services to different industries, is an accredited lab for field uniformity calibration precision. They provide the calibration services that will assure you that you are receiving a reliable EMC source. The key objective in EMC site validation is Field Uniformity Testing, which is vital for generating precise and repeatable results in the RF immunity testing phase.
What is Field Uniformity in EMC Testing?
Field Uniformity relates to the spatial uniformity of electromagnetic fields over a defined test area in an EMC chamber. The IEC 61000-4-3 Field Uniformity, establishes the field strength at the test plane must be maintained within ±1.25 dBto provide consistent exposure throughout the radiated RF immunity tests. At BQuest Labs, we conduct Field Uniformity Testing for RF immunity compliance in accordance with IEC 61000-4-3:2020, covering the 80 MHz to 18 GHz with Measurement range 1 V/mto 20 V/m @ (80MHz to 18 GHz) field uniformity measurement range. Our experts follow strict protocols to measure and verify field consistency in 3m or 10m test chambers.
Field Uniformity Calibration Process
Bquest Labs EMC Field Uniformity Measurement process includes evaluating electromagnetic fields at multiple points—typically 16—across a horizontal test plane. We use calibrated isotropic probes, high-power RF amplifiers, and broadband signal generators to conduct Field Uniformity Calibration accurately. If the field strength at any point deviates beyond the permissible range, we adjust antenna placement, power levels, or chamber configurations to restore compliance. This uniformity check in 3m/10m EMC test chamber ensures that your Device Under Test (DUT) receives uniform field exposure throughout testing.
Anechoic Chamber Field Uniformity Testing
Bquest labs have up-to-date anechoic chambers built to reduce the potential for reflections or interference. These chambers are ideal for conducting EMC Chamber FU Testing with high precision. We ensure the electromagnetic environment within the test chamber is fully compliant with global standards, minimizing the risk of test result inconsistencies.
Why Field Uniformity Matters
Inconsistent field strength can compromise test accuracy. A DUT might pass testing in one zone of the chamber and fail in another due to field variation. Potential costly redesigns, delays in product launch, or even regulatory rejection. Field Uniformity Testing, as performed by BQuest Labs, eliminates this risk by ensuring consistent, validated field conditions.
