Distortion measurement and correction system and method

A computer program product residing on a computer readable storage medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations for determining a magnitude and phase of a distortion component comprising:

• receiving 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.
