Precise optical spectrum analysis with high resolution by an economical and reliable device is of much interest in optical science and technology. In this work, we propose a silicon-photonic ...

Spectrum analyzer for multiple SDR platforms (PyQtGraph based GUI for soapy_power, hackrf_sweep, rtl_power, rx_power and other backends) - xmikos/qspectrumanalyzer ...

Not yet another spectrum analyzer — an experimental DSP & graphics playground. It combines real-time C++ performance with Python flexibility, offering fully customizable FFT visualizations without ...

We present an architecture for millimeter-wave spectrum analyzers with Hz resolution and precision based on heterodyne down-conversion using ErAs:InGaAs photoconductive mixers driven by a tunable ...
