This paper describes a new method that enables time domain pulsed RF measurements with a sub-sampling system. It consists of replacing the FFT with a rectangular windowed short-time Fourier transform. The algorithm automatically extract Fourier coefficients within the pulses and the system does not need any trigger signal or clocking circuit. This minimal software modification enhances the standard Large Signal Network Analyzer, enabling pulsed measurements without any hardware modifications.
