The Tektronix 1503C Metallic-cable Time-Domain Reflectometer (MTDR) is a cable test instrument that uses radar principles to determine the electrical characteristics of metallic cables. It generates a half-sine wave signal, applies it to the cable under test, and detects and processes the reflected voltage waveform. These reflections are displayed in the 1503C liquid crystal display (LCD), where distance measurements may be made using a cursor technique. Impedance information may be obtained through interpreting waveform amplitude. The waveform may be temporarily stored within the 1503C and recalled or may be printed using the optional dot matrix strip chart recorder, which installs into the front-panel Option Port.

The 1503C may be operated from an AC power source or an internal lead-acid battery that supply a minimum of five hours operating time. The battery pack is a standard feature of the 1503C and is user-replaceable. The instrument is designed to be rugged and portable, with a durable case and a handle for easy carrying. The Model 1503C MTDR is a versatile and reliable cable test instrument that is ideal for a wide range of applications. It is suitable for use in a variety of industries, including telecommunications, power generation, and transportation. The device is designed to be easy to use, with a simple interface and intuitive controls. It is also rugged and portable, making it ideal for use in the field.
