Eliminating FFT Artifacts in Vector Signal Analyzer Spectra

This article presents a method to minimize the spectral leakage in measurements of periodic signals made with a vector signal analyzer (VSA) by taking into account the periodic nature of the Fast Fourier Transform (FFT). This method negates the need fo...
The vector signal analyzer (VSA) has several measurement advantages over a spectrum analyzer in the acquisition of bandpass RF signals, including its time-domain capture, which enables measurement of both magnitude and phase information, and its ability to display data in the time and frequency domains. 1,2 The highly sampled,...
