ABSTRACT OF THE DISCLOSURE A method for measuring crossview between channels in a wired television broadcasting system is described in which a pseudo random binary pulse sequence signal is applied to a first channel, and the signal on a second channel is correlated with an identical sequence to provide an output representative of the crossview between the first and second channels. This enables crossview measurements to be easily made without interrupting television signals on the channels. The pseudo random binary pulse sequence signal may be applied directly to the first channel or modulated on a carrier for application to the first channel.
