Coaxial Cable Testing

Coax is gaining popularity as the medium of choice for transferring

communications in and around customer premises. Whether the technology is

broadcast or IP video, data over coax technologies, or whole-home digital video

recorder (DVR) services, the IW-1000 can ensure that the inside coaxial plant

is properly connected. The IW-1000 also helps technicians detect and eliminate

unwanted coaxial elements such as hidden splitters, bad barrels, and damaged

cables.

Coax Map

The Coax Map feature of the IW-1000 is a single-ended coax physical layer test

based on frequency domain reflectometry (FDR), a powerful technique used in

analyzing RF transmission lines. The Coax Map test measures signal quality as it

passes through the transmission line by identifying impairments that cause

standing waves.

Coax Active Identification

The IW-1000 helps technicians quickly identify which cable goes to which room

in a house. Using the Cable ID mode, technicians can determine coax wire

endings for each room with a coax run. A common problem occurs when an

unexpected splitter exists in the middle of the coax run. However, the Active IDs

of the IW-1000 work through splitters to display multiple IDs, which helps to

locate the wall outlet or outlets that are connected via a splitter network.

Noise Immunity Test

The Noise Immunity Test (NIT) provides good indications of coaxial cable

shielding issues. Problems arise when the inside coax has staples, sheared

jacketing, an exposed stinger, or an unterminated end present. The NIT gives

technicians a better chance of catching impairments before subscribers

experience service degradation. The NIT measures the signal strength of local FM

carriers and compares them to the same measurement on the cable to determine

the isolation of the coax to off-air ingress.

The NIT helps users locate isolation issues in coax

cable to identify which legs contain faults that could

allow ingress into the coax network
