APS and FRF are the most used analysis types.  APS is our internal term, Auto-Power Spectrum, it is what is commonly thought of as an FFT power spectrum and has a wide array of applications.  FRF are sometimes called transfer functions and describe the relationship between input and output. Reference channel will default to time stream data from channel 1 of the data source provided from previous step.

-Make selections for block size / spectral lines to determine ∆f and dynamic range. Overlap ratio, recommended at least 50% for Hanning window. Average mode and average number based on testing requirements. Window selection can be left as Hanning for most testing applications; Uniform may be desired for shock or transient impulse testing.+Make selections for block size / spectral lines to determine ∆f and dynamic range. Overlap ratio, recommended at least 50% for Hanning window. Average mode and average number should be adjusted based on testing requirements, if no direct requirements to change these settings leave as default. Applying a window to the data has a smearing effect which allows for the signal to be treated as periodic within time blocks.  Each window type has slightly different properties, Hanning is good for precisely distinguishing between different sine waves.  Flattop windows are good for identifying peaks.  The data Window selection can be left as Hanning for most testing applications; Uniform may be desired for shock or transient impulse testing.
