Defining the Analysis Parameters
RMS/RMS Peak
The RMS and RMS Peak algorithms calculate the root mean square value
of the
power data above a given
Width Threshold
, taking the full power data (RMS) or
simply the Power at Peak (RMS Peak) for the calculation.
Gaussian Fit/Lorentzian Fit
The Gaussian Fit and Lorentzian Fit algorithms fit a curve to the data and calculate
the spectral parameters using
Width Threshold
from this fit.
If
Modal Analysis
is set to OFF (see
Fitting Options
below), the curve fits a Gaussian
or Lorentzian to the main peak.
If
Modal Analysis
is set to ON, the curve fits a Gaussian or Lorentzian to all peaks
above
Mode Threshold
.
