New version of XMachina: [ 1180209 ]. An option to digitize impedance characteristics in logarithmic scale has been added to the axis definition window. (For example Scan-Speak data datasheets use logarithmic impedance charts). Few simple tools have been implemented in the measurement simulator, supporting to estimate characteristics outside the loaded range. The characteristics can be “tailed” with a specified slope or extrapolated with a slope calculated from the characteristic shape at the edge. In case of impedance characteristics, values of DC resistance (Re) and voice coil inductance (Le) can be utilized for the estimation (Re for low and Le for high frequency range). Estimation improves the accuracy of phase calculation. It was used also in the previous version but only as an “on the fly” action during the acceptance of measurements simulator results.
