Upload the code to ESP32 using Arduino, or any other method you prefer. Pay attention on the problems with the analogRead function described in the documentation. Use the sketch in sketch_sample_rate ...

First-person-view (FPV) flying, by adding a camera, video transmitter, and video goggles to the meat on the ground, is one of the best ways to experience remote-controlled flight. For just a few hu… ...

This guide will walk you through the steps required to set up a virtual environment using venv and run the real-time FFT visualization application. Ensure your Arduino is connected to the correct ...

However, their spectrum analysis abilities are lacking. While these scopes do have a Fast Fourier Transform (FFT) function, it’s limited and nearly useless for RF.

This paper describes a new high speed spectrum analysis technique that tiles a spectral display using a rapid step and dwell spectral sweep. The step and dwell translation operates as a block down ...

This paper belongs to a set of efforts aimed to improve the education of engineering in electronic and telecommunications, based on virtual equipment. It stand on a previous work called Networking ...

RF spectrum analyzers have been popular since the 1960s. A considerable evolution in technology and capability has taken place inside the spectrum analyzer over the years. Today, three basic types ...

The spectrum analyzer uses a fixed number of 1024 samples for each FFT acquisition. That fixed size, combined with an FFT-overlapping process and a FFT rate of 146,484 FFT/s, results in a gap-free ...

Although a spectrum analyzer exhibits better dynamic range and less distortion, the digital oscilloscope FFT provides a cost-effective, space-saving alternative.
