The Fitting Tool is an optional function supplied as an add-in to the standard measurement software.

The tool calculates series and parallel resonance frequency as well as frequencies of maximum and minimum impedance/admittance by fitting an idealized resonance function into measurement data, based on least square algorithm.

The following characteristic parameters are derived for Serial and Parallel Resonance frequency plots:

• fres = Resonance Frequency
• HVW = Half Value Width
• Q = Q-value (= fres / HVW)
• max = Height of peak
• min = Base line

The following characteristic parameters are derived for Resonance and Anti-Resonance frequency plots (= frequency plots of max/min impedance or admittance):

• fn = Frequency of min. impedance (max. admittance)
• |Z|min (|Y|max) = Min. impedance (max. adm.) value of the fit function
• fm = Frequency of max. impedance (min. admittance)
• |Z|max (|Y|min)  = Max. impedance (min. adm.) value of the fit function

Implementation of automated fitting routines and related data processing is possible as part of our customized add-ins development services.
