Tektronix 1502C-04

Wavelength: 1310/1550

TDR Cable Tester

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

Applications include LANs, On-Board Systems and Manufacturing QC. The general purpose 1502C Portable MTDR Cable Tester generates a 1/2 sine pulse, with selectable pulse widths of 2, 10, 100, or 1000 ns. The high-resolution 2 ns pulse permits the identification of multiple faults as close together as one foot. The 1000 ns pulse gives the 1502C a range of 5,000 to 50,000 feet (depending on cable type and condition). The ultra-high-resolution 1502C Portable MTDR Cable Tester generates a 200 ps rise time step pulse and has an output impedance of 50 ohms. The fast rise time permits the identification of multiple faults as close together as 0.6 inches. For most TDR applications, where determining distance to an impedance change is the key measurement, the 1502C is the best choice.

Typical Cable Measurements:

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