Innovative Viavi Ct-4 Digital Leakage Channel Tagger Trilithic Tri-lkg-ct4 120 - 240 Vac Ps Massive 45% Savings [e2EkOjvK]

Condition: Used

Key Features
  • Generates proprietary dual CW Carriers for use with the Seeker D and Seeker D Lite Digital Leakage Detectors
  • Operates in both the aeronautical (135– 139 MHz) and LTE (610.5–615 MHz) frequency bands
  • Adjustable output from 10 to 30 dBmV
  • Carriers injected at ~30 dB below adjacent digital carriers, eliminating the risk of affecting digital services
  • 8 available tag settings for digital leakage 
The CT-4™ is a 1U rack-mounted unit located in the headend that provides an uncompromising tagging solution for active analog or digital systems. 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-4 is designed to deal with the problem of leakage identification in up to 8 overbuilt situations. Used as a system with VIAVI leakage receivers, the CT-4 eliminates all “false alarm” triggers and increase leak detection sensitivity by four times over un-tagged systems.

The CT-4 works in conjunction with Seeker D™ and Seeker D Lite Digital Leakage Detectors to accurately detect and measure signal leakage within the LTE and aeronautical frequency bands at the same time. The Seeker D detects the proprietary signal from the CT-4 with an unsurpassed sensitivity of 2 to 2000 μV/m (20 to 2000 μV/m for the Seeker D Lite) with measurements that are scaled to an analog or QAM carrier of your choice. Consequently, readings taken from the existing Seeker meter and the new Seeker D and Seeker D Lite meters produce similar results in the aeronautical band, if the low band correlation of the Seeker D and Seeker D Lite is set to analog. Whether testing for leaks in both digital and analog systems, or monitoring aeronautical or LTE bands, the CT-4 used in conjunction with the Seeker D and Seeker D Lite provides all of the capability to find and fix leaks quickly, accurately, and effectively.
