We discuss two different techniques for the comparison of polarization signal in magnetic fields, the calibration curves and derivative methods, for the case of an imaging magnetograph. The advantages and typical errors of both techniques are analyzed in respect to the instrumental characteristics, particularly the spectral response. Both methods present high degree of errors, but the calibration curves method is probably more suitable for the present instrumental configuration of the SVMG.
