sVSWR Chamber Validation (1 GHz – 18 GHz)
Don’t settle for testing that adds complexity and risk to your schedule. Shielding Integrity Services (SIS) delivers expert, fully accredited, independent sVSWR Chamber Validation 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.
Test Objectives
The Site Voltage Standing Wave Ratio (sVSWR) test is a critical requirement for evaluating test site suitability above 1 GHz. It measures the reflections from the chamber walls, floor, and ceiling to ensure they do not excessively interfere with the direct signal from the Equipment Under Test (EUT).
Technical Specifications
sVSWR testing is required as operating frequencies for modern electronics continue to climb.
- Frequency Range: Validation is performed in the 1 GHz to 18 GHz range.
- Test Distances: Typically conducted at a 3-meter test distance.
Methodology
Because high-frequency beams are highly directional, sVSWR utilizes a volumetric test approach to ensure the entire quiet zone is compliant.
- Measurements are taken using specialized omnidirectional antennas.
- We evaluate multiple positions within the defined test volume by moving the receive antenna along a specific line-of-sight path.
- Our automated positioning systems ensure highly repeatable, precise data capture, minimizing chamber downtime.
Standards & Performance
This measurement verifies compliance with the industry’s most trusted international standards for high-frequency anechoic performance. Validation is performed in strict accordance with CISPR 16-1-4, ensuring your facility provides accurate and legally compliant data.
