limeSNA ported to ADALM-PLUTO

This is a Scalar Network Analyzer program initialy written for the LimeSDR mini by github user nepeee (https://github.com/nepeee/limeSNA).
I replaced the SoapySDR layer by pow tool, and added Pluto TXgain and RXgain controls to the webpage.
Sweep time is not optimal and can be improved : approx. 1 hop/s

Dependencies

  • pow tool : you will need to compile pow tool.
    build pow tool :

    gcc -std=gnu99 -g -o pow pow.c -liio -lm -Wall -Wextra
    

    Test :

    ./pow -l 430600000 -g 40 -f 3   
    

    result : 430600000 2.49 95.75
    units : freq (Hz), signal (dB) computed by pow, RSSI (dB) returned by pluto through IIO

  • numpy (pip)

  • flask (pip)
