The Trilithic CT-2 Channel Tag is a headend-mounted device used with
Trilithic's leakage receivers used to help identify leakage sources
in overbuilt areas, to increase detection range and to increase
immunity to interference. When several CATV systems operate in the
same area, it is often difficult to determine which system is the
source of a detected leak. The CT-2 solves this problem by "tagging"
the system video carrier, with low-frequency modulation. This
modulation is ignored by TV sets, but causes a distinctive response
in Trilithic's SEARCHER PLUS leakage receiver, SUPER PLUS
leakage receiver, SEARCH LITE leakage receiver, and the
TRICORDER signal level meters when operated in leakage mode.
Used as a system with the Super Plus leakage receiver, the CT-2
eliminates all "false alarm" triggers and increases leak detection
sensitivity by four times over previous models. |
