A system for measuring radio frequency power of an incoming radio frequency signal is described, with at least one radio frequency interface for receiving the radio frequency signal, a signal processing unit for processing the radio frequency signal, a frequency selection unit for separating at least two frequency bands of the incoming radio frequency signal, the frequency selection unit comprising several filters, at least one power detector for measuring the radio frequency power of at least one of the frequency bands processed by the at least one power detector. At least one of the several filters is connected with the at least one power detector. The frequency selection unit is configured to forward the incoming radio frequency signal to at least one of the filters wherein the frequency selection unit has at least a first operation state in which the incoming radio frequency signal is forwarded to more than one filter simultaneously or subsequently.
