EMC & RF ComplianceEMC Testing

Emission & Immunity

o Radiated & Conducted Meanso Limits & Classes

ITE(Information Technology Equipment), Audio/Video, ISM (Industrial, scientific, Medical) Products

Goal: Certified for Industrial or Home/Offices Uses

EMC & RF ComplianceEMC Tests

• Conducted Emissions• Radiated Emissions• Electrostatic Discharge

(ESD) immunity• Radiated field Immunity• Conducted disturbances

immunity• Voltage surge immunity• Electrical fast

transient / burst immunity

• Voltage fluctuation / flicker

EMC & RF Compliance

RF Testing

Wireless & RF technologyGenerally, @ unlicensed band, multiple

systems coexist and interfere• 802.11 networks, Bluetooth

systems, walkies-talkies• Spectrum Sharing Rules

Goal : fair, efficient and compatible sharing of Frequency

EMC & RF ComplianceRF Tests

Basically,• Maximum Output Power• 6dbm Channel

bandwidth (Emission Bandwidth)

• Maximum Peak Power Spectrum Density

• Unwanted Emissions in Non-Restricted Bands

• Unwanted Emissions in Restricted Bands

• Band Edge Measurement

Economics & Market Value

• Vital in Product Launch

• Affecting in business strategy, program management, and organizational design

• Regulatory Authorities Inspection

• Third Party Certification Bodies

Technical ChallengesFixed and mobile transmitter

Higher frequency, more severe immunity test Required

Facility to host large systems, inaccuracy of measurement

Widespread of fear on EM field, introducing health effects measurement in EMC & RF

Flaw in standardization as time is limited

EMC knowledge is not encouraged, economy and academic

Technology TrendsProliferation of Processors

Higher Operating Frequency

Large Equipment and Systems

Health & Electromagnetic Fields

Accelerating Product Life cycles

Paucity of EMC engineers & Economy

Trends of Technology

• CR(Cognitive Radio) - Dynamics Spectrum

Access

• Smart Grid- systems of systems(More Electronics Components & Compliance issues)

• Nuclear Facility Compliance for EMC

Importance of RF & EMC TestingSAFETY & HEALTH for Society

• Current & Future Technology (More Interference)

• Emergency Situations

• High Reliance on electronics devices in daily

• Continuous advantageous of employing high mobility electronics

Conclusion

•Consistency of the Standards

•Standardization for easy reference for developers

•Evaluate and Focus on future

•Co-ordination of Standards committee, Industrial Partners and Business Dealer
