Bandwidth and sweep time of FFT EMI receivers
Aussteller Round Table von Narda Safety Test Solutions S.r.l.
Nowadays Fast Fourier Transform is the standard technique adopted in spectrum analysis and in EMI receivers too.
One of the advantages of this algorithm is to reduce process time since a relatively wide portion of the spectrum, the so called FFT bandwidth, is simultaneously analyzed.
When considering bandwidth, which is in theory directly proportional to emission test speed, compliance with CISPR 16-1-1 must also be kept in mind.
