The portable, rugged 1502B TDR Cable Tester is a portable maintenance tool that is simple to operate and will test most dual conductor metallic cable under virtually any condition. The 1502B identifies and locates cable faults. When the tester is connected to the line to be tested it sends out electrical pulses that are reflected back to the tester by impedance changes in the cable. The 1502B displays impedance changes in the cable as a function of distance. Moving the cursor to the displayed fault produces an on-screen readout of distance to the fault.

The 1502B transmits 200 ps rise time step pulses down the cable under test. The reflected energy is displayed on the LCD and the type of fault can then be determined by the user. When testing 50 ohm cable with a velocity of propagation equal to 0.66, the 1502B Metallic TDR allows the determination of 0.5 ohm cable faults. Multiple faults as close together as 0.8 of an inch can be resolved.

The 1502B offers a variety of parameters and information that can be accessed using menus. The main menu allows you to access Help Screens, Velocity Propagtion Values, Impedances of Different Cables, Instrument/Front Panel Configurations and Instrument Diagnostics.
