Spectrum Analysis of Signals

Downstream spectrum analysis of signals using MATLAB®, Communications Toolbox™ and DSP System Toolbox™. You can either use captured signals, or receive signals in real time using the RTL-SDR Radio, ADALM-PLUTO Radio or USRP™ Radio. You can change the radio's center frequency to tune the radio to a band where a signal is present. You can then use the spectrum analyzer to view and make measurements on the received spectrum.

Spectral Analysis of signals in Simulink®

Use the captured signals, or receive signals in real time using RTL-SDR, ADALM-PLUTO or USRP™ radio, as a data source for downstream spectrum analysis with MATLAB® and Simulink®. You can change the radio's center frequency to tune the radio to a band where a signal is present. You can then use the spectrum analyzer to view and make measurements on the received spectrum.
