Abstract
A system and method for performing wide-band spectral analysis of transient signals using a real-time spectrum analyzer (RTSA). A frequency window is selected for RTSA acquisition, the frequency window being narrower in bandwidth than the frequency spectrum of interest. An RTSA is successively tuned to a plurality of different frequencies within the frequency spectrum of interest, where such successive tuning is controlled based on a characteristic of the signal. The RF signal is received, and, for each of the plurality of different frequencies, power data is acquired for the signal in a band centered on the frequency and having a bandwidth equal to that of the frequency window. A representation of the frequency spectrum of interest is then constructed from the power data acquired during the successive tunings of the RTSA.
