Abstract :
The inadequacy of deterministic methods to correlate measurements from a radio frequency (RF) semianechoic absorber lined chamber and open area test site is discussed. An alternate method for statistically estimating correlation is given, based on a large number of measurements of computing products typically tested at the facilities being correlated. Statistical correlation is shown as a chamber enhancement that increases electromagnetic interference (EMI) testing productivity
