Patent ID: 8798198

Claim:
A method of calibrating an electronic device having wireless communications circuitry with a calibration system, wherein the calibration system includes data acquisition equipment and calibration computing equipment and wherein the wireless communications circuitry comprises a calibration pattern generator and local oscillator, the method comprising: with the wireless communications circuitry, transmitting an amplitude-modulated calibration signal to the data acquisition equipment; with the data acquisition equipment, transferring the amplitude-modulated calibration signal to the calibration computing equipment; with the calibration computing equipment, extracting a phase drift correction from the amplitude-modulated calibration signal; with the calibration computing equipment, extracting pre-distortion coefficients from the amplitude-modulated calibration signal; with the calibration pattern generator, generating a known amplitude-modulated calibration pattern; with the local oscillator, generating a carrier signal; and with the wireless communications circuitry, before transmitting the amplitude-modulated calibration signal to the data acquisition equipment, modulating the carrier signal with the known amplitude-modulated calibration pattern to create the amplitude-modulated calibration signal.
