SpectraVue Capabilities

• FFT analysis using 2048 to 262144 point FFT's
  (real or complex).
• FFT amplitude resolutions from 10dB to .2dB per
  division.
• FFT amplitude power is in dB referenced to full
  scale (a single sine wave with amplitude of
  /-32767 or 16 bits).
• Various FFT data view modes including waterfalls
  and 2D and 3D plots.
• Display markers for accurate amplitude/frequency
  measurement.
• A continuum display for measuring spectral power
  over the entire span and/or the peak power within
  the span.
• Frequency Spans from 5KHz to 30MHz in various
  step sizes.(using SDR-14 unit)
• Signal demodulation of AM, NBFM, USB, LSB, narrow
  CW modes when using the 100 KHz Frequency Span
  and SDR-14 unit.
• Saving and playback of captured spectrum using
  RIFF .wav files.
