That is correct. You'll get 80 sweeps per second across 100 MHz. (In a test I just ran for verification, I had 81.37 sweeps per second.) > What kind of computer does one need to run something like hackrf_sweep > than returns the FFT, with a resolution of 100kHz ie 10 bins per MHz? With 100 kHz bin width, my test used 20% of one core of this CPU: model name : Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz bogomips : 5427.48 Bin width is the main thing that affects CPU utilization.
