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.

sudo apt install libiio-dev libncurses5-dev libboost-program-options-dev libgpm-dev
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.
