This project presents the operating principle, analytical dimensioning, and experimental characterization of an analog heterodyne spectrum analyzer.
The system was entirely developed at the functional block level—including a triangular wave generator, voltage-controlled oscillator (VCO), analog multiplier, band-pass filter, and an AC-RMS converter. It was subsequently implemented and validated in the laboratory on a breadboard, with a detailed analysis of real-world non-idealities such as mixer feedthrough phenomena and the dynamic limitations of the active components.
