Abstract
An fast Fourier transform analyzer with capabilities of auto-configuration, continuous signal analysis, and estimation of spectral component parameters has been provided with the capability of evaluating the uncertainty of the estimated values. The instrument, which has been implemented on a two-DSP hardware, has been characterized through several experimental tests, proving the metrological and operating performances. This paper describes the hardware and the algorithms used for the instrument, and it details the analytical development of the relationships for the uncertainty evaluation and the preliminary compensation of systematic effects. This paper also reports the main experimental results.
