-Auto-power Spectra
+**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,
-The most common FFT analysis type.  Displays frequency spectrum resulting amplitude after FFT and data processing.
+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.
+**Frequency Response Function:** Often referred to as transfer functions, FRF describe the relationship between the input and output functions.  Result is commonly displayed in Frequency v Phase & Frequency v EU similar to FFT analysis.
