TESTING INSTRUMENT FOR CATV NETWORKS

摘要

An instrument (20) for testing a CATV network includes an input port (52, 64 ) for receiving first information from the network, a computer (22) coupled to input port (52, 64) for processing the first information received from the network, a user interface (34) permitting a user to create second informatio n for communication over the network, and a serial port (52) for coupling the second information to the network. The instrument (20) also includes a signature pad (54) permitting a user to enter handwritten communication for transmission over the network, and a port (430) for coupling handwritten communication-related signals to the network. The instrument (20) also includes an ethernet interface (56) for coupling (494) the second informatio n to the network.
