According to one exemplary embodiment, a method of preventing harmonics from causing distortion in a communications system includes feeding a test signal through a pre-distortion circuit in the communications system to a transmitter in the communications system. The method continues by transmitting a distorted output signal produced by the transmitter to an analyzer, analyzing the distorted output signal to identify one or more undesired harmonics, and generating and sending calibration data from the analyzer to calibrate the pre-distortion circuit, thereby preventing the one or more undesired harmonics from causing distortion in the communications system. In one embodiment, a system to prevent harmonics from causing distortion in a communications system includes a pre-distortion circuit, a transmitter, and an analyzer configured to identify one or more undesired harmonics and to generate and send calibration data to prevent the undesired harmonics from causing distortion.
