In this paper, Timothy Hegarty Applications Engineer from Texas Instruments offers some perspective on standards for radiated emissions, particularly those pertaining to automotive, multimedia and industrial applications.
Today’s automobiles have increased their electronic content, with numerous microprocessors, various radio-frequency (RF) transmitters and receivers, motor drive systems, and associated power management. Tracking all possible interactions that might lead to a radiated EMI problem is a formidable task – particularly given the relatively small volume in a vehicle characterised by densely packed arrangements of power and signal runs in the cable harness.
Nevertheless, it is possible to test components and systems in order to meet automotive EMC requirements. As such, assessing EMI performance is an issue of heightened concern for engineers involved in automotive design and testing.
