Diagnosing RF cable faults requires meticulous attention to keep communication systems operational and functional without failure. One method, time-domain reflectometry (TDR), examines the cable pulse's response to check for breaks or impedance mismatches. Frequency-domain reflectometry (FDR) evaluates the frequency-response characteristics of a cable. In addition to TDR and FDR, other important methods include visual inspections for damages using advanced cable testers which have specialized diagnostic tools. Such testers enable cable technicians to conduct rapid assessments confirming the continuity of smooth and uninterrupted RF signal transmission.
