Overview

Time-Domain Reflectometers (TDR) are specialized instruments used to locate faults in cables, such as breaks, shorts, or impedance mismatches. By sending a signal down a cable and measuring the reflected signal, TDRs can accurately pinpoint the location and nature of the fault. They are commonly used in telecommunications, network maintenance, and other fields requiring precise cable diagnostics.

FAQ

What should I consider when buying a used TDR?
