Abstract

A digital signal processor (DSP)-based FFT analyzer capable of adapting its behavior according to specific application requirements was set up. A suitably designed user-interface allows both the specific application to be chosen and its main parameters to be defined. An automatic optimization procedure then reorganizes the instrument configuration in order to meet user requirements. 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
