## Overview

The TL280 Cable Fault Tester is a professional-grade TDR locator designed for coaxial and communication cables up to 4km. Featuring an ARM CPU with FPGA technology, it delivers rapid and accurate fault waveform analysis enhanced by digital gain control and automatic waveform recognition. Its daylight-visible color LCD and 10-hour lithium battery empower field technicians to diagnose cable faults efficiently and reliably, making it an indispensable tool for network professionals.

## Description

Review: A really good piece of equipment. It does a snapshot analysis which is helpful. If you need to live monitor an issue it becomes awkward to constantly refresh the scan. I would have given it 5 stars if it did that. Over all it’s pretty easy to use and works well for common troubles
Review: A cable fault tester is a must have tool for those working in the field of networking of coaxial cable. This fault tester has a pretty long distance measurement range of 2.4 miles on auto. The screen is very clear and bright. You can tell someone designed this to be seen easily outdoors during the daytime. Once you understand the functions of the machine, it is easy to navigate. I would have liked to have seen a little longer battery time so that you have a little extra buffer between days, but for the type of device it is, 10 hours is quite a bit. I like the fact that it’s a multi-function cable fault tester as well, making it a more versatile device. Overall, it gives a lot of data, in order to diagnosis the fault problems and is worth the investment.

## Features

- DAGC (Digital Gain Automatic Control) system: The gain can be modified digitally. Eliminate the waveform distortion caused by the potntiometer knob. It can also do pure linear adjustment, which is convenient for manual testing.
- Using ARM CPU with FPGA technology, can quickly perform various complex operations and determine fault waveform accurately.
- Digital waveform automatic recognition technology: automatically recognize the waveform that are difficult for human to determine.
- Waveform comparison function, it is convenient to compare the test waveform of the fault cable and the normal cable, and clearly find the fault point location.
- High-power lithium battery, which can be used for up to ten hours (with specialized power charger). With data interface to support customers upgrade the system remotely..Large-screen LCD color display, humanization design of the interface menu, fast digital press button, easy for users to operate.
