Abstract
A calibration apparatus calibrates cross-frequency phases of large-signal network analyzer measurements and includes: a signal generator; a vector network analyzer that includes couplers and receivers that receive the calibration signal and the reference multitone signal from the signal generator; a calibration receiver that receives a calibration signal from the vector network analyzer and produces a digitized calibration temporal signal from the calibration signal; and a signal processor in communication with the signal generator and the vector network analyzer and that: receives the reference digitized signal from the reference receiver; receives the forward digitized signal from the forward coupled receiver; receives the reverse digitized signal from the reverse coupled receiver; receives the digitized calibration temporal signal from the calibration receiver; and produces a calibration factor from the reference digitized signal, the forward digitized signal, the reverse digitized signal, and the digitized calibration temporal signal.
