A digital signal processor (DSP)-based FFT analyzer capable of adapting its
behavior according to specific application requirements was set up. A suit
ably designed user-interface allows both the specific application to be cho
sen and its main parameters to be defined. An automatic optimization proced
ure then reorganizes the instrument configuration in order to meet user req
uirements. Multi-DSP architecture implementation ensures real-time behavior
. The experimental test results indicate that the instrument is capable of
optimally operating in a large number of typical applications.
