Abstract
For determination of the transmission function of a measurement apparatus, in particular of a spectrum analyzer, a calibration signal, modulated with a modulation signed such that a line spectrum arises within the frequency band of interest is provided in the measurement apparatus. In a computer, the modulation signal is calculated from the digitized output signal of the measurement apparatus. The desired transmission function is then calculated therefrom according to magnitude and phase.
