<p>The present invention relates to a method for calibrating a receiver device or a stimulus-response system comprising a receiver device. The method comprises the steps of generating at least one tone with a repeatable and known phase value, said at least one tone being stepped in frequency to cover a given set of calibration tones, and applying the at least one tone to the receiver device or to the stimulus-response system, generating a reference signal, which is phase-coherent with the at least one tone, to measure in a phase-coherent way with the receiver device or with the stimulus-response system the at least one tone, measuring at least the phase of the at least one tone using the receiver device or the stimulus-response system, determining at least phase-related information for calibration coefficients at the given set of calibration tones by calculating a phase deviation of the measured phase from the known phase value of the at least one tone.</p> |
