A Time-Domain Reflectometer (TDR) is an electronic measurement device used to determine the characteristics of electrical lines by observing reflected waveforms. It is commonly employed for analyzing various types of transmission lines, including coaxial cables, twisted pairs, and waveguides, as well as for testing and locating faults in these lines. \#\#\# How TDR Works: 1. **Signal Transmission**: The TDR transmits a short pulse of electrical energy through the transmission line.
