the number of samples in the source waveform. If the source waveform contains fewer samples that required (that is, fewer than twice the number of the frequency bins), then MaxiSope will zero-pads the waveform up to the next power of two. For example, if the scope view contains 10,000 samples, and you set Spectrum Bins to 16,384, then MaxiScope zero-pads the waveform to 16,384 samples, which is the nearest power of two above 10,000.
