Shared Networks- Cheking Coaxial Cable 

Before   dealing   with   any   shared   network   to 
provide   the   ability   to   distribute   data   using 
CoaxData modem, you must know whether the 
network has its return channel in optimal state.

This requires the following equipment:

• 

Advanced   coaxial   network   analyzer   to 

measure the noise in the return channel  as 
Televes H45 or H60 spectrum analyzers.

• 

Signal Noise Generator ref.5930

• 

CoaxData   Gigabit   Diplexer   filter: 

ref.769220:   Data   (2-65Mhz)   and   TV   (87-
2150Mhz)
