Abstract
A monitor for a transmitter, receiver, or transceiver is proposed. The transmitter, receiver or transceiver has at least one component with at least one varying setting parameter controlled by a parameter controller to adjust a spectral degradation of a signal processed by the transmitter, receiver, or transceiver. The monitor comprises an input for receiving the at least one varying setting parameter from the parameter controller, and a setting parameter analyzer for evaluating the at least one varying setting parameter to determine whether the at least one component is normally operating within a desired operating range and to issue a warning signal in case the at least one component is abnormally operating within the desired operating range. The varying setting parameter may be, for example, predistortion parameters or tuning parameters of a voltage controlled oscillator. A corresponding method for monitoring a transmitter, receiver or transceiver is also proposed. Furthermore, a computer program product comprising instructions for the manufacture of the monitor and a computer program product that enable a processor to carry out the monitoring method are proposed.
