Plot a spectrum from a CSV file using the format of rtl_power from RTL-SDR.
This is a fork of Kyle “Keenerd” Keen repository, only keeping files under the
original heatmap directory. His version is unmaintained since several years,
yet this utility is still useful for spectrum offline plotting. In this fork, I
only maintain compatibility with newer versions of Python and dependent
libraries.
In the current directory, simply wget the needed utility and launch it with
python. For example:
wget https://raw.githubusercontent.com/pierreay/heatmap/master/heatmap.py
python heatmap.py- flatten.py
- Summarize a
rtl_powerCSV by printing to the standard output the magnitude of each frequency band over the whole sweeping time. - heatmap.py
- Plot a
rtl_powerCSV into an image representing the spectrum. - raw_iq.py
- Plot raw I/Q data (e.g.,
numpy.complex64) into the same image format and style thatheatmap.py.
