Wideband Spectrum analyzer on your terminal/ssh console with ASCII art. Hacked from Ettus UHD RX ASCII Art DFT code for ADALM PLUTO.
Pan & Zoom spectrum using keyboard controls [decrement-Increment]. [Full feature demo]
- Center Frequency using keys [f-F]
- Sampling rate using keys [r-R]
- Bandwidth using keys [b-B]
- Gain using keys [g-G]
- Reference level using keys [l-L]
- Dynamic Range using keys [d-D]
- Frame rate using keys [s-S]
- Peak Hold using keys [h-H]
- DFT bin count using keys [n-N]
- Tuning step using keys [t-T]
- Hide/Show controls using keys [c-C]
- Quit program using keys [q-Q]
Tuning step applies for decrementing / Incrementing Center Frequency, Sampling Rate and Bandwidth.

Requires: libiio, libcurses, libboost-program-options
sudo apt install libiio-dev libncurses5-dev libboost-program-options-dev libgpm-dev
Build:
For running a Linux host with Pluto connected via USB / Ethernet / Wifi.
make
Compiling static binary for arm (raspi / pluto - requires libtinfo-dev libgpm-dev):
make arm
Static binaries for running natively on Pluto can be built on Raspberry Pi (or cross-compiled). The static binary can then be scp'ed to Pluto after build - steps shown below.
Run:
./retrogram-plutosdr --rate 5e6 --bw 5e6 --freq 100e6 --step 1e6
Max rate/bw/gain:
./retrogram-plutosdr --rate 61e6 --bw 56e6 --gain 73 --freq 935e6 --step 5e6
Run natively on Pluto (static binary - requires 'linux' terminfo files):
wget https://github.com/r4d10n/retrogram-plutosdr/raw/master/retrogram-plutosdr.arm
scp retrogram-plutosdr.arm root@192.168.2.1:/tmp
scp /usr/share/terminfo/l/linux root@192.168.2.1:/tmp (or)
wget https://github.com/r4d10n/retrogram-plutosdr/raw/master/linux
scp linux root@192.168.2.1:/tmp
ssh root@192.168.2.1
cd /tmp
mkdir /usr/share/terminfo
mkdir /usr/share/terminfo/l
cp linux /usr/share/terminfo/l
export TERM=linux
chmod +x ./retrogram-plutosdr.arm
./retrogram-plutosdr.arm --rate 61e6 --bw 56e6 --gain 73 --freq 935e6 --step 5e6
