The 1500C Series is designed to quickly and easily locate opens, shorts, crimps, and other defects in metallic cables. The 1502C can measure up to 2,000 feet (625 meters).

Using a process similar to radar, the 1500C Series transmits electrical pulses down the cable under test. Impedance changes in the cable reflect some of the pulse energy back to the MTDR. The reflections are displayed on a backlit, HyperTwist, high-contrast nematic LCD display. The characteristics of the displayed trace allow the user to determine the nature of the cable fault.

When testing 50 Ω cable with a Vp of 0.66, the 1502C allows the determination of 0.5 Ω cable faults. Multiple faults can be measured as close as 0.8 inch. The 1502C measures 50 Ω impedance.

Typical Cable Measurements
  • Distance to faults
  • Cable propagation velocity
  • Cable return loss in dB
  • Faulty taps and unterminated line in LAN and CATV networks
