 The Model CLI-1750, used in conjunction with the Model LST-1700 Signal Transmitter, helps identify and locate potential problems with the distribution network and home wiring prior to activating these new services.
The CLI-1750 and LST-1700 are compact home wiring testers capable of measuring not only routine power levels, but also digital average power, leakage, frequency domain reflectometry (FDR), and sweep, which can be useful for a wide range of trouble shooting from installation to characterizing existing wire. The instruments' superior user interface and performance can reduce the installation time and repair cost.
Designed for use by installers, the CLI-1750 and LST-1700 are easy to use, portable, and economical solutions that perform a comprehensive set of tests to verify the quality of the installation.
With these instruments, signal levels are checked to verify proper levels arriving at the tap and the house according to design and government regulations.
Frequency response is measured to verify proper losses as a function of cable length, type, number of passive components, and to uncover any roll-off or sharp changes in response.
A FDR test reveals precise location of sources of reflections, degree of severity, and enables surgical replacement of faulty cable or components, or repair of craftsmanship problems.
A reverse ingress scan test shows the presence of noise or ingress generated in the home that hampers reverse communication for all customers sharing the node. A leakage test finds potential points of ingress because the source of ingress may not be in operation while the installer is at the house.
