Time Domain Reflectometers

Time Domain Reflectometers (TDRs) are essential tools for cable testing and fault location. They offer a clear picture of coaxial or twisted pair cable lengths and accurately pinpoint cable faults. TDRs work based on the principle of sending an electrical pulse down the cable and measuring the reflections that occur when the pulse encounters impedance changes, such as cable ends, splices, or faults. These reflections are then displayed on the TDR screen, providing valuable information about the cable length and the location of any faults or anomalies.

We supply a range of TDRs offering a variety of features and capabilities that meet various testing and fault locating specifications. These products provide high-resolution measurements, adjustable output impedances, selectable velocity factors, and user-friendly interfaces for easy operation. They are designed to be portable, durable, and reliable, making them suitable for use in various industries such as telecommunications, power distribution, and network installation.
