Abstract
A method and arrangement is shown for measuring an indicator of delay mismatch between a phase information path and an amplitude information path of a polar modulator. In the solution according to the invention a substantially sinusoidal measurement signal () is injected both into the amplitude information path () and into the phase information path (). An indicator of the delay mismatch is obtained by measuring a quantity that is proportional to a difference between power represented by a lower side band of a spectrum of a polar modulated signal and power represented by an upper side band of the spectrum.
