Measurement and system for performing a calibration

A calibration system for calibrating a first system, the calibration system comprising:

• a synthesizer circuit configured to:
• generate a set of calibration tones one tone at a time with a repeatable known phase value and a different frequency value with respect to a most recent previously generated tone;
• and
• generate a reference signal which is phase-coherent with each generated tone;
• and
• a processor circuit configured to:
• apply each generated tone to the first system, one tone at a time;
• and
• determine at least phase-related information for a set of calibration coefficients corresponding to the set of calibration tones by calculating a phase deviation between a respective measured phase of each generated tone and the repeatable known phase value.

A method for calibrating a receiver device or a stimulus-response system comprising a receiver device, the method comprising:

• generating, by a synthesizer circuit, a set of calibration tones, comprising generating one tone of the set of calibration tones at a time with a repeatable known phase value and a different frequency value with respect to a most recent previously generated tone, and applying each generated tone to the receiver device or to the stimulus-response system one tone at a time;
• generating, by the synthesizer circuit, a reference signal, which is phase-coherent with each generated tone, to measure each generated tone in a phase-coherent way with the receiver device or with the stimulus-response system;
• measuring at least a respective phase of each generated tone using the receiver device or the stimulus-response system;
• and
• determining, by a processor circuit, at least phase-related information for a set of calibration coefficients corresponding to the set of calibration tones comprising calculating a phase deviation of the measured respective phase from the repeatable known phase value for each generated tone.
