Radiated Emissions Testing (RE)
Radiated Emission Testing
Radiated Emission (RE) testing is a fundamental component of Electromagnetic Compatibility (EMC) testing, used to evaluate the unintended electromagnetic energy emitted by electrical and electronic products across the radio frequency spectrum. The purpose of radiated emissions testing is to verify that the Equipment Under Test (EUT) complies with the emission limits specified by applicable international EMC standards, supporting EMC compliance, regulatory compliance, product certification, and access to global markets.
Excessive electromagnetic emissions can propagate through free space and interfere with wireless communications, electronic control systems, sensitive instrumentation, and safety-critical equipment. By performing comprehensive radiated emission testing at an accredited EMC testing laboratory, manufacturers can identify potential compliance issues early, demonstrate conformity with EMC requirements, and support certification pathways such as FCC Certification, ISED Certification, CE Certification, and other international approval schemes. Stancer Testing-Lab provides accredited EMC testing services to help manufacturers achieve efficient product certification and global market access.
Benefits of Radiate Emission Testing
- Ensures regulatory compliance with CISPR, FCC, ICES, and other global EMC standards.
- Mitigates the risk of electromagnetic interference (EMI) with nearby communication systems, sensors, and industrial control electronics.For both sub‑6 GHz and mmWave frequencies enabling clients to leverage next‑generation connectivity
- Improves product reliability by identifying unintended emissions early in the design cycle.
- Reduces field failures and warranty costs associated with EMC-related malfunctions.
- Supports the safe integration of equipment in environments containing sensitive or safety-related electronics, including medical device EMC testing, automotive EMC testing, aerospace systems, industrial automation, and other applications requiring electromagnetic compatibility (EMC) compliance and product reliability.
- Enhances market access by ensuring conformity for multiple regions (North America, EU, Asia-Pacific).
- Optimizes design performance through diagnostic pre-compliance testing and emission source identification.
At Stancer Testing-Lab, our radiated emission testing capability covers a wide-range of frequencies from 9 kHz to 325 GHz, enabling us to assess everything from low-frequency industrial equipment to advanced wireless, Radar and mmWave/RF systems. This broad coverage ensures full compatibility with global EMC regulatory requirements across commercial, automotive, aerospace, medical, and IT sectors.
Our Process and Testing Capabilities
All measurements are performed in our state-of-the-art 3-meter semi-anechoic chamber, engineered with high-performance hybrid absorbers to maintain stable free-space conditions. A full set of power line filter (with 100dB attenuation), ensures the test environment is electromagnetically isolated, delivering clean, accurate, and repeatable measurements.
Our services are aligned with leading EMC standards, including CISPR 11, CISPR 22/32, CISPR 25, FCC Part 15, ICES-003, and UNECE R10, covering a wide spectrum of product categories from industrial and IT equipment to communication devices and automotive modules.
To ensure high precision and fast turnaround, we rely on the Rohde & Schwarz ESW44 EMI receiver integrated with Elektra automation software for fully automated scanning, limit analysis, and reporting. This advanced system provides precise, repeatable results while significantly streamlining the test process.
Our experienced EMC engineers oversee each step from test configuration and maximization procedures to final compliance assessment delivering reliable, efficient, and industry-standard radiated emission testing for all product types.
