This article describes one of the most valuable tools in the EMC engineer's “bag of tricks” – the high-frequency current probe. Current probes are invaluable for measuring high-frequency common-mode (or “antenna”) currents flowing on wires or cables. Experience has proven that poorly terminated (bonded or filtered) cables are the no. 1 cause for radiated emissions failures at a … [Read more...]
The Urgent Need to Integrate EMC and Product Safety into Engineering Curriculum of Technical Universities
There is an evolution in the study of electromagnetic field effects on electrical and electronic products and systems. It is progressing from an engineering art to an engineering science. The complexity and sophistication of newer technology products has added to an increased need for more consideration of EMC and Product Safety issues. These factors have increased the … [Read more...]
Alternatives in EMI Connectors
There is no generic solution for all problems associated with I/O interfaces ORVILLE HAAS, WILLIAM E. KUNZ SOURCES OF RF INTERFERENCE WITH CLOCK FREQUENCIES of a few gigahertz, today's electronic systems are using pulse edges in the subnanosecond range. Networking interfaces deliver data rates in excess of 100 Mbits/s (Fast Ethernet and FDDI—fiber distributed data interface) … [Read more...]
