Video Demonstrations
This video demonstrates why crossing a clock, or other
high speed signal, over a split in the (ground) return
plane is bad news for EMI.
This fun video shows some experiments done with a
low-cost Tesla coil!
This video demonstrates why pigtails in I/O cables is
bad news for EMI.
This simple spreadsheet for analyzing clock harmonics
was developed by my coauthor, Patrick André and is also
available on his web: http://andreconsulting.com.
The current probe is one of my most used tools during
EMI troubleshooting. The purpose is to measure the very
small RF currents in a wire or cable that can
potentially cause radiated emissions failures. This
video demonstrates how to use the current probe.
Ringing on switch-mode power supply waveforms can cause
a broadband peak in EMI. This video demonstrates this
effect.
This video explains how to use near field probes to
help troubleshoot EMI problems.
This video demonstrates how several common devices can
generate broadband noise (or EMI), which may be used to
assess the radiated RF immunity of an electronic
product.
This video demonstrates some unique sources of ESD you
may use to help assess the immunity of your product
prior to compliance testing.
