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.

Spectrum Analysis of Signals in Simulink

Use Simulink® and Communications Toolbox™ to perform spectrum analysis of the downstream signals. You can tune the radio to a band where a signal is present by changing the center frequency. You can then use the spectrum analyzer to view and make measurements on the received spectrum. You can either use recorded data from a file, or receive over-the-air signals in real time using an RTL-SDR radio, ADALM-PLUTO radio, or USRP™ radio.
