Condition: Used

The Viavi CT-X (Trilithic TRI-LKG-CT-X) is a fully agile digital leakage channel tagger designed for CATV headend installations. It generates up to 4 simultaneous tagged carriers anywhere in the 130–1220 MHz channel lineup, supporting both next-generation digital chirp tagging (for use with the Seeker X detector) and Seeker D-compatible dual CW tags. This allows a single CT-X unit to serve mixed detector fleets including Seeker X, Seeker D, and Seeker D Lite. The CT-X is engineered to address leakage identification in overbuilt situations where multiple CATV systems operate in the same area. Installation is straightforward via front-panel push-buttons or integrated web interface, requiring only 1RU of rack space near the combiner.

The Viavi CT-X Digital Advanced Leakage Channel Tagger (also known by Trilithic part number TRI-LKG-CT-X) is a professional-grade CATV headend transmitter designed to enable high-sensitivity, full-band RF signal leakage detection across modern cable plant infrastructures.

The CT-X supports next-generation digital chirp tagging technology, which — when used in conjunction with the Viavi Seeker X leakage detector — delivers dramatically improved leak detection sensitivity while rejecting false positives. It also generates Seeker D-compatible dual CW tags, ensuring backward compatibility with existing Seeker D and Seeker D Lite detector fleets.
