A transmitter is configured to transmit data to a receiver over a communications network. The transmitter includes a memory for storing computer-executable instructions and a processor in operable communication with the memory. The processor is configured to (i) collect spectrum data of a spectral band over a first sampling interval, and (ii) store the collected spectrum data in the memory. The transmitter further includes a common path distortion (CPD) detection unit configured to (i) sample the collected spectrum data, over a second sampling interval less than the first sampling interval, for a plurality of sub-bands within the spectral band, (ii) analyze the spectral band and each sub-band for indications of common path distortion, and (iii) inject a test signal configured for detection at a headend of the communications network. The transmitter further includes a modem portion configured to operably communicate with the headend and the receiver.
A transmitter configured to transmit data to a receiver over a communications network, the transmitter comprising:
