Designation: Associate Engineer Department : Electrical & Electronics Center, EMC and Telecoms Job Scope: Test Officer, testing electronics products for EMC certification Specialized: RF testing Certification and Auditing Services Testing Services Inspection Services Product Certification Services PSB Learning Products from Service Quality (SQ) Centre – Training and Consulting
Overview • Technology Development • EMC Testing • RF Testing • Future Technology Trends • Technical Challenges • Economics & Market Value • Importance of EMC & RF compliance in society
Technology Developments • Electronics Revolution ( Starting in 1947 ) • World’s 1st Microprocessor, the 4004 ( 1971) • Satellites and Wireless Communications • GSM mobile Phones & Internet Services • RFID technology • Home & Office Appliances • Industrial & Military Systems
Impact on Society • Efficiency • Productivity • Mobility • Communication • Ease of daily life Operations Interoperability Interference Crowded Spectrum Accidents due to interference
EMC & RF Compliance Compatibility with Environment EMC testing RF testing Regulatory Authorities • IEC • CISPR • ETSI • FCC • BSI
EMC & RF Compliance EMC Testing Emission & Immunity • Radiated & Conducted Means • Limits & Classes ITE(Information Technology Equipment), Audio/Video, ISM (Industrial, scientific, Medical) Products Goal: Certified for Industrial or Home/Offices Uses
EMC & RF Compliance EMC 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 technology Generally, @ 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 Compliance RF 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
Technology Trends • Proliferation of Processors • Higher Operating Frequency • Large Equipment and Systems • Health & Electromagnetic Fields • Accelerating Product Life cycles • Paucity of EMC engineers & Economy Technical Challenges Fixed 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
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 Testing SAFETY & 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
