Distortion measurement and correction system and method

摘要

A method, computer program product, and computer system for determining a magnitude and phase of a spurious-free dynamic range component. A first signal and a second signal may be received from a first source operatively connected to a differential component. A first output associated with the first signal and a second output associated with the second signal may be nulled. The first signal and the second signal may be shorted. A second source operatively connected to the differential component may be disconnected. The first signal of the first source may be applied at a same phase as the second source with an additional phase delta, +Y∘. A first differential residual signal may be measured using the first signal at the same phase as the second source with the additional phase delta, +Y∘. The second signal of the first source may be applied at the same phase as the second source with an additional phase delta, −Y∘. A second differential residual signal may be measured using the second signal at the same phase as the second source with the additional phase delta, −Y∘. The magnitude and phase of the distortion component of the first source may be determined based upon, at least in part, the first and second differential residual signal.

1. A computer-implemented method for determining a magnitude and phase of a distortion component comprising:
receiving, by a computing device, a first signal and a second signal from a first source operatively connected to a differential component; nulling a first output associated with the first signal and a second output associated with the second signal; shorting the first signal and the second signal; disconnecting a second source operatively connected to the differential component; applying the first signal of the first source at a same phase as the second source with an additional phase delta, +Y∘; measuring a first differential residual signal using the first signal at the same phase as the second source with the additional phase delta, +Y∘; applying the second signal of the first source at the same phase as the second source with an additional phase delta, −Y∘; measuring a second differential residual signal using the second signal at the same phase as the second source with the additional phase delta −Y∘; and determining the magnitude and phase of the distortion component of the first source based upon, at least in part, the first and second differential residual signal.
