IEC 61000-4-3 Radiated RF Electromagnetic Field Immunity Testing
Radiometrics Midwest Corporation provides IEC 61000-4-3 radiated RF electromagnetic field immunity testing at our A2LA-accredited EMC laboratory in Romeoville, Illinois.
IEC 61000-4-3 is used to evaluate the immunity of electronic and electrical equipment to radiated radio-frequency electromagnetic fields. The test helps determine whether equipment will continue to operate as intended when exposed to RF energy that may be present in its operating environment.
Radiometrics performs IEC 61000-4-3 testing in characterized EMC test environments using calibrated RF generation, amplification, field monitoring, and test systems appropriate for the required frequency range and field strength.
What Does IEC 61000-4-3 Testing Evaluate?
IEC 61000-4-3 testing exposes the equipment under test (EUT) to a controlled radio-frequency electromagnetic field while the equipment is operating and being monitored.
The RF field is swept through the required frequency range using the modulation, frequency step size, dwell time, field strength, antenna polarization, and equipment orientations specified by the applicable standard or test plan.
During exposure, the EUT is monitored for degradation of performance, unintended operation, loss of function, data errors, resets, or other responses that may affect its ability to meet the required performance criteria.
Radiometrics IEC 61000-4-3 Testing Capabilities
Radiometrics maintains multiple EMC test environments for radiated RF immunity testing. Our facilities allow us to select an appropriate test environment based on the size and configuration of the equipment under test, required field strength, frequency range, and applicable test specification.
Our IEC 61000-4-3 testing capabilities include:
- Testing in characterized electromagnetic field environments
- Horizontal and vertical antenna polarization as required
- Multiple equipment orientations when required by the applicable test plan
- Controlled frequency stepping and dwell times
- Continuous monitoring of RF field strength during testing
- Operation and monitoring of the equipment under test during RF exposure
- Testing at field strengths and frequency ranges specified by the applicable product standard or customer test plan
- Engineering assistance when susceptibility is observed during testing
Multiple RF Immunity Test Environments
Radiometrics operates multiple EMC chambers and shielded test environments. This provides flexibility in matching the test facility to the size and configuration of the equipment rather than relying on a single test chamber for every IEC 61000-4-3 program.
Our compact semi-anechoic and fully anechoic test chambers include uniform-field characterization for IEC 61000-4-3 radiated immunity testing. This allows many electronic, industrial, medical, laboratory, and commercial products to be tested efficiently in an appropriately sized EMC environment.
What Determines an IEC 61000-4-3 Test Program?
The time required for IEC 61000-4-3 testing can vary significantly depending on the applicable product standard, customer specification, and configuration of the equipment under test.
Factors that can affect the test program include:
- Required frequency range
- Required field strength
- Frequency step size
- Dwell time at each frequency
- Number of antenna polarizations
- Number of equipment orientations
- Number of operating modes
- Equipment monitoring requirements
- Product setup and support equipment
Because the RF field is swept through the specified frequency range, seemingly small differences in frequency step size or dwell time can substantially affect total test time. Programs requiring multiple equipment orientations, antenna polarizations, or operating modes may require the frequency sweep to be repeated for each required configuration.
Providing the applicable standard or customer test specification before scheduling allows Radiometrics to determine the required test parameters and develop a more accurate estimate of laboratory time.

IEC 61000-4-3 Pre-Compliance Testing and Troubleshooting
Radiated RF immunity problems can be difficult to predict from design review alone. Pre-compliance testing can help identify RF susceptibility before a product enters its final compliance program.
If a product exhibits unintended operation, resets, communication errors, measurement errors, loss of function, or other performance changes during RF exposure, Radiometrics can work with your engineering team to help identify the susceptibility and evaluate corrective changes.
When appropriate, modifications can be evaluated during the test program to determine whether they improve the product’s RF immunity before final testing is completed.
