Abstract
The present invention relates to testing signals on a coaxial home network that carries a digital video signal. It has direct application to testing so-called Multimedia over Coax Alliance (MoCA) standards-compliant networks and applies to similar networks. In one mode, a computerized device joins the MoCA network and relays signals intended for a set-top-box to the STB. In another mode, the computerized device joins the MoCA network instead of the STB and tests signal strength, attenuation and similar physical layer characteristics.
