Model 87 time-division reflectometer locates bridged taps and faults and measures lengths to within one foot on installed cables. The TDR also measures up to 1500 feet of cable on a reel. This handheld device locates open, shorted and good cable pairs from one end of the cable, without the use of a remote adapter. Two built-in RJ-45 jacks and a BNC connector are included for testing systems.
