The Evolution of EMI Receivers

Since the discovery of electromagnetic interference (EMI) in the early 1900s, the need for testing for radiated emissions continues to grow as products get more complicated. The time to test has also grown, and, in some cases, can take days to complete. The introduction of fast Fourier transform (FFT) technology into EMI receivers can greatly decrease the required testing time, but is it applicable for everyone?
