IEC 61000-4-3 Testing & Field Uniformity Validation

Don’t settle for testing that adds complexity and risk to your schedule. Shielding Integrity Services (SIS) delivers expert, fully accredited, independent IEC 61000-4-3 Testing based on decades of practical, hands-on experience—not just theory. We use state-of-the-art automated systems that maximize testing efficiency, ensuring fast turnaround of accurate data and quick troubleshooting for any required performance adjustments. Whether validating a compact 3-meter setup or a specialized 10-meter facility anywhere in the world, SIS delivers the precise, compliant results you need to confidently move your projects forward.

Field uniformity testing is essential for radiated immunity measurements. The homogeneity of the field in the test area (the “quiet zone”) must be proven to guarantee that your device under test (DUT) is exposed to a consistent, standardized field strength.

Test Standard & Necessity

Primary Test Standard

The most commonly performed and recognized method of field uniformity measurement is IEC 61000-4-3.

• This validation ensures that deviations in field strength across the test volume meet strict international limits.

SIS Automated Methodology: Speed and Precision

What previously was a time-consuming task, taking days to perform, we can now complete in a few hours thanks to our proprietary technology. This dramatically reduces your chamber downtime and expense.

Automated System Advantage

• We employ a patented, fully automatic probe positioning system with proprietary measurement software to maximize performance, accuracy and efficiency.
• The equipment is configured to establish the required field strength at each test frequency (typically 80 to 6 GHz in 1% increments).
• After leveling, the system automatically shuttles the probe, reconfigures generator levels, and records the data points.

Test Range & Accuracy

Our standard capabilities ensure comprehensive validation across critical frequency ranges, confirming performance even in the most challenging chamber environments.

Measurement Parameters

• Measurement Range: Our standard capabilities cover measurements in the 80 MHz to 18 GHz range.
• Data Integrity: When all sixteen points are measured and compared with the first leveling point, a deviation is precisely extracted from the recorded data values.

Expert Troubleshooting & Chamber Support

We are not just testers; we are experts in troubleshooting and resolving field uniformity issues in all types of facilities.

• New Facilities: We perform initial measurements on newly installed facilities.
• Problem Resolution: We specialize in troubleshooting and resolving complex field uniformity issues in existing chambers.

SIS Chamber Testing is the efficient, expert solution for meeting your IEC 61000-4-3 requirements.
