1. A method utilizing a signal source having a plurality of signal outputs coupled to particular circuit and provide inputs thereto, the particular circuit having an output, the method comprising the steps of:

  • applying a training configuration to the signal source to highlight imperfections within the signal source and within the particular circuit;

    measuring parameters, during application of the training configuration, to develop an error model representing the imperfections in the signal source and in the particular circuit, wherein at least some of the parameters are measured at the plurality of signal outputs, and wherein at least one of the parameters is measured at the output of the particular circuit; and

    applying compensation to the signal source based on the parameters, which compensation affects the plurality of signal outputs and compensates for the imperfections in the signal source and in the particular circuit;

    wherein;

    the imperfections are related to amplitude and phase imbalance among at least two of the plurality of signal outputs; and

    the step of measuring parameters further comprises the step of measuring power level at the plurality of signal outputs from the signal source, and at the output of the particular circuit, to determine the parameters.
