The 1500C Series is designed to quickly and easily locate
opens, shorts, crimps, and other defects in metallic cables. The 1503C
can measure cables up to 50,000 feet (15,000 meters) in length; 2,000
feet (625 meters) for the 1502C.
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 Ohm cable with a Vp of 0.66, the
1502C allows the determination of 0.5 Ohm cable faults. Multiple
faults can be measured as close as 10 inches with the 1503C or 0.8 inch
with the 1502C. The 1503C can measure cables with impedances of 50, 75,
93, and 125 Ohm; the 1502C measures 50 Ohm impedance only.
Typical Cable Measurements
- Distance to faults
- Cable propagation velocity
- Cable return loss in dB
- Faulty taps and unterminated line in LAN and CATV networks
