Real-time spectrum analyzer

Post by jeanminet » Thu Dec 10, 2015 6:20 pm

Hello,

We've been working on implementing a spectrum analyzer on the FPGA.
4096-points FFTs are computed in real-time and averaged over-time:

The FPGA has been designed using the tcl-based approach from https://github.com/pavel-demin/red-pitaya-notes.
You can find the source code at https://github.com/Koheron/koheron-sdk.

The Graphical User Interface is written in Python using PyQtGraph (https://github.com/pyqtgraph/pyqtgraph).
You can find the source code at https://github.com/Koheron/laser-development-kit.

Cheers,
Jean
