-**Auto-power Spectra:** The most common FFT analysis type.  Displays frequency spectrum resulting amplitude after FFT and data processing.+**Auto-power Spectra:** APS is our in-house terminology for a standard FFT analysis.  Displays frequency spectrum corresponding amplitude after FFT and data processing. Typically results are displayed in Hz (Frequency) on the X-axis,  
 +EU Y-Axis scaled to dB, LogMag, or Lin Mag.
  
-**Frequency Response Function:** Often referred to as transfer functions, FRF describe the relationship between the input and output functions.  +{{::fft.gif?}}
