All electronic products which are intended for commercial, residential, industrial or military use must pass EMC (Electromagnetic compatibility) and electromagnetic interference (EMI) standards tests. They must perform their intended function in the electromagnetic environment and also must not degrade the performance of other devices.
These standards are country specific and are governed by local organizations. The EMI testing on electronic equipment for the United States is handled by the Federal Communications Commission (FCC) and is commonly referred as Part 15 testing. The EMI testing for Canada is presented in the Industry Canada ICES-003 standard. In Japan the EMI testing standard is outlined by VCCI. Majority of worldwide standards are derived from Comite International Special des Perturbations Radioelectriques (CISPR) standards or International Electrotechnical Commission (IEC) EMC/EMI/ESD standards.
EMC and EMI tests are often performed late in the product development cycle, generally at the system level using expensive anechoic chamber. This approach leads to lengthy development cycle and turns out to be very expensive if violations are discovered at this stage.
It is recommended to opt for design analysis services if your product is time or mission critical. Many optimizations can be done at PCB design phase and layout can be modified with minimal cost and effort.Using design, analysis and verification techniques early in design cycle is recommended as it helps in eliminating many layout iterations.
Analysis of radiated emission, far and near field emission , EMC emission can be done. SI and crosstalk issues can be resolved at this stage These analyses provide insights that helps in successful regulation compliance testing and thus avoid costly hardware re-spins and reduce time-to-market.
Argus Embedded System in USA, UK and India offers various design analysis services including EMI and EMC simulation services and will help you in Identifying EMI/EMC related problems early in the design cycle to ensure success of your new product.
