Patent ID: 7949039

Claim:
A testing device for home networks comprising: an input port for inputting a home network signal, the input port including connectors for mating with at least one cable selected from the group consisting of coaxial cables, telephone cables, and electrical cables; a first filtering apparatus for removing all signals from the home network signal except those in a measurement band of a first home network technology generating a first filtered signal; a second filtering apparatus for removing all signals from the home network signal except those in a measurement band of a second home network technology, different than the first home network technology, generating a second filtered signal; measuring equipment connected to said first and second filtering apparatuses for determining which home network technology is present on a home network; and switches for selecting which one of the connectors to be connected with which one of the first and second filtering apparatuses, and which one of the first and second filtering apparatuses to be connected with the measuring equipment; wherein the measuring equipment comprises: an amplitude demodulator for generating a resultant voltage signal; and a transformer for conducting a fast Fourier transform on the resultant voltage signal generating a transformed signal.
