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

Figure 2

Block diagram of the cross-correlation method. This method uses two independent reference sources (REF1, REF2) and phase detectors (mixers). The two baseband outputs are measured with a cross-spectrum analyzer.
