Implementation of a Cross-Spectrum FFT Analyzer for a Phase-Noise Test System in a Low-Cost FPGA

<div>Cross-correlation phase-noise measurement of a free-running wideband VCO at 2.16 GHz with the APPH6040. Single correlation (blue) and maximum correlation (brown) per individual decades. Same measurement time of 1.2 sec for both traces.</div>
