Megahertz [MHz]

If you’re an electrical engineer and consider proper EMC shielding a mechanical only issue, please reconsider your position and keep reading. Proper EMC shielding is both an electrical and mechanical design issue. Thoughtful coordination between the two disciplines is key to successful EMC shielding implementation on most product development projects.

Single electromagnetic pulses like lightning, ESD, powerline transients, NEMP, etc., are generally described in time domain, while filters and shields are practically always characterized in frequency domain. This article describes a quick and handy formula and nomogram providing a fair estimate of the filter or shield response to a conducted or radiated threat.

This article discusses the common-mode and differential-mode radiation from cables and presents the measurement results from the SMPS connecting wires.

Ever tried to measure low-level signals in the presence of noise? Or wanted to capture a measurement isolated from ground, like that of an ungrounded hand-held digital multi-meter, but also needed to capture finer details of the signal, like those captured with an oscilloscope?

CDM discharges exhibit a fast initial current step when the stray capacitance of the pogo pin is charged. It is demonstrated that the high slew rate can damage sensitive gate oxides. The miscorrelation of CDM and CC-TLP methodologies is addressed by applying pulses with 20 ps rise time.
