Communications Test CFL 510 G Handheld TDR 1

The New Megger CFL 510 G n Auto Set Up • Instant use n Fast 2 ns Pulse • Near end fault identification n Long Reach • 15, 000 ft maximum range n Simple Operation • 4 way control n Trace hold feature • On screen comparison n High Definition Display 2

Technology n Well proven n Long used technology n Electrical, telephone and CATV industries. n Increasing in use • Provide information on cable status much faster than other methods. • Some industry commentators suggest that a TDR will be built into many instruments in the future 3

Product Uses n TDRs are typically used to find existing faults on cables and have more applications in related areas such as: • • • Defining and proving a cable installation Establishing a benchmark for future comparison Cable length measurement (installed and on reel) Locate and evaluate events such as splices and joints Detect Bridge taps 4

Additional Uses n Also research by NASA suggests that Aircraft Maintenance can be aided by regular TDR measurement n TDR may be used to identify chafing of electrical wires on aircraft 5

TDR Overview n TDRs locate and identify faults on metallic paired cable n TDRs look for a change in impedance on the cable • Cable damage, water ingress, taps and slices, flaws, etc. n A pulse of energy is transmitted down a cable • When the pulse reaches the end of the cable, or a fault, part of the energy is reflected back • The reflected pulse can identify the nature and location of the fault n Used in Electrical, telephone and CATV industries. • Provide information on cable status much faster than other methods 9

Typical TDR Reflections n TDR used to locate cable faults and determine length n Shape of reflected pulse indicates fault type n Knowing VOP for cable allows distance to fault to be displayed n Length of cable on drum can be determined n Variable pulse widths enable location of near and far faults 10
