OKI Engineering (President: Hiroyuki Oba, Head Office: Nerima-ku, Tokyo, hereinafter 'OEG'), which provides technical services for reliability evaluation, environmental testing, and EMC testing within the OKI Group, will launch a new 'Radiated Noise Measurement Service using Reverberation Chamber (Note 1: hereinafter 'RVC')' for multimedia equipment such as information, video, and audio devices, starting April 24, 2026. This service responds to the need for 1GHz-6GHz band radiated noise measurement under near-real-world conditions, supporting customers in shortening development periods and reducing evaluation costs through quick and highly accurate assessments. The company aims for 200 million yen in sales over three years until fiscal year 2028.
In recent years, with the improvement of communication speed and processing capability, multimedia equipment has seen an increase in operating frequencies. This raises the risk of interference and communication failures with wireless communications such as mobile phones and Wi-Fi. In addition, the international standard CISPR 32 (Note 2), which defines noise measurement for multimedia equipment, proposes the addition of RVC as a method for radiated noise measurement in the 1GHz-6GHz frequency band. Development sites are therefore demanding measurement methods that are closer to real-world conditions and highly reproducible.
Based on approximately 10 years of RVC expertise and achievements cultivated through immunity testing (Note 3), OEG has been at the forefront of developing RVC-based radiated noise measurement technology among domestic testing laboratories. Furthermore, by collaborating with test equipment manufacturers, OEG has developed measurement software, enabling the provision of this service. A key feature of RVC measurement is its high reproducibility and short measurement time, as it is less dependent on the placement conditions of the object within the test chamber. This is expected to reduce the burden of retesting and condition adjustments, contributing to shorter development periods and more efficient evaluation operations. OEG employs iNARTE-EMC Engineer (Note 4) holders who are well-versed in RVC operation and provides services under a quality management system as an ISO/IEC 17025 accredited testing laboratory (Note 5).
Moving forward, OEG plans to closely monitor the latest EMC standard trends for multimedia equipment and various other electronic devices, and to rapidly develop and provide new evaluation methods. Through this, the company will support customers in product development, quality improvement, and reliability enhancement, contributing to technological innovation and strengthening international competitiveness in Japanese manufacturing.

Reverberation Chamber Overview
Glossary
Note 1: Reverberation Chamber (RVC)
A test chamber that creates a random electromagnetic field inside by reflecting radio waves with metal walls and a stirrer.
Note 2: CISPR 32
An international standard established by the International Special Committee on Radio Interference (CISPR) regarding 'Electromagnetic compatibility of multimedia equipment – Emission requirements.'
Note 3: Immunity Testing
Testing to evaluate whether electronic equipment operates normally when exposed to external radiated noise.
Note 4: iNARTE-EMC Engineer
A global technical qualification that certifies EMC technology and skills.
Note 5: ISO/IEC 17025 Accredited Testing Laboratory
An accreditation system where the technical competence and quality management system of a testing laboratory are internationally recognized.
Note 6: EMC
Electromagnetic Compatibility. The ability not to emit noise and to withstand noise within an acceptable range.
