Radiated Emission Testing

Radiated Emission (RE) testing assesses the unintentional electromagnetic energy emitted by electrical and electronic equipment across the RF spectrum. The objective is to verify that the Equipment Under Test (EUT) does not exceed the permissible emission limits specified in international EMC standards. Excessive radiated emissions can couple into nearby systems through free-space propagation, potentially degrading the performance of communication links, sensitive electronics, or safety-critical subsystems

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.
  • Improves product reliability by identifying unintended emissions early in the design cycle.
  • Reduces field failures and warranty costs associated with EMC-related malfunctions.
  • Supports safe integration of equipment in environments with sensitive or safety-related electronics (medical, automotive, aerospace).
  • 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.

Our Process and Testing Capabilities

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.

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.
