WebNov 22, 2024 · Time domain reflectometers (TDR) are test devices that generate an energy pulse or step on the cable to determine the location and magnitude of cable faults, breaks, splices, terminations, or other events along the length of a conductive cable. What are the advantages of TDR over regular Ohmmeters when troubleshooting cables? WebBased on a modified integrating sphere, it measures total reflectance at seven sub-bands in the 300-2500nm spectral regions. Total, diffuse, and specular reflectance is reported for the data at 20 degrees incidence. A total of twenty-one data points are produced during a single data acquisition cycle.
