Calibration method and calibration system

A calibration method for calibrating an electronic device is described. The method comprises: generating a test signal having a predefined bandwidth, said test signal comprising an asymmetric signal component being asymmetric in frequency domain, and said test signal further comprising a symmetric signal component being symmetric in frequency domain; processing said test signal via said electronic device, thereby generating a response signal of said electronic device to said test signal; analyzing said response signal, thereby generating measurement data comprising information on impairments due to at least one of a frequency selective channel of said electronic device and an IQ mismatch of said electronic device; and adapting at least one operational parameter of said electronic device based on said measurement data in order to calibrate the electronic device. Further, a calibration system is described.
