Reverberation chambers, Mode-Stirred and Mode-Tuned Testing,
resonant cavities...
We hear these terms often in
the EMC community. But what's behind this technology--Is it really that
new? And why is it important for EMC testing?
The physics of resonance has
been studied and applied for years. We recognize its importance in acoustics
for musical instruments and concert halls, and also with mechanical vibrations
in buildings, bridges, and machinery. More recently, nuclear magnetic resonance
and optical resonance in lasers have brought new understanding and great
benefits to our everyday lives.
Here at Elite, resonance and
reverberation chamber technology are used for testing digital electronics for
RF susceptibility. Mode-Tuned testing in our reverberation chambers provides a
very robust evaluation of RF susceptibility because of the characteristic
"isotropy, random polarization, and uniformity" of this
method.
To
help explain this very interesting convergence of electromagnetics and
statistics, Elite will host an IEEE
technical presentation on reverberation chamber testing for
EMC. Don't miss this great opportunity to learn about this topic and why
concepts like isotropy and random polarization make a difference for your EMC
tests...And it's Oktoberfest-themed!
