A system and method of monitoring a signal repeating device in a wireless communication system is provided. An operational noise measurement is obtained by measuring a noise value outside of a bandwidth of a first element, but within a bandwidth of a second, subsequent element in a signal path of the device. The operational noise measurement is alternatively obtained by tuning an input band of the device to shift the input band partially or completely outside of a bandwidth of a first element to create an open band or by suppressing an input of an antenna and measuring noise within the open bandwidth of the device. A stored parameter is retrieved and compared to the measured operational noise. Alternatively, a leakage signal of the device may be received at a signal receiver and compared to a reference. The reference is a function of elements of the device in a leakage path of the leakage signal. |
