1. A method for testing faults and non-conformities in a waveguide of a transmitting station for radio or television, comprising:
generating an ultra-wide-bandwidth signal with a transmitter,
injecting the ultra-wide-bandwidth signal in the waveguide,
receiving a backscattered signal with a receiver,
generating a nonconformity or a fault along the waveguide based on the backscattered signal.
