  • Method Details

    • getCenterFrequency

      int getCenterFrequency()
       Center Frequency [Hz].
      uint32 center_frequency = 1;
      Returns:
      The centerFrequency.

    • getSampleRate

      int getSampleRate()
      
 Sample rate [Hz].
 Observed band is [-sample_rate/2,+sample_rate/2),
  centered at (center_frequency).
      uint32 sample_rate = 2;
      Returns:
      The sampleRate.

    • getFftSize

      int getFftSize()
      
 FFT size, i.e. number of samples used in a single FFT block.
 This translates directly into the number of frequency bins of the FFT
  result. Each bin has bandwidth (sample_rate / fft_size).
 Thinking of a waterfall plot, this is the number of steps of the x axis
  (frequency).
      uint32 fft_size = 3;
      Returns:
      The fftSize.

    • getAggregationFactor

      int getAggregationFactor()
      
 Number of FFT blocks aggregated into an aggregated FFT block.
 The duration observed for a single FFT block is
  (fft_size / sample_rate). Accordingly, the duration observed for an
  aggregated FFT block is (aggregation_factor * fft_size / sample_rate).
      uint32 aggregation_factor = 4;
      Returns:
      The aggregationFactor.
