Fault location and structural return loss
(Option 100)
For fully characterizing cable performance and antennafeedline systems, this option provides both fault-location
and structural-return-loss capability. Fault-location measurements help identify where cable or system faults,
such as bends, shorts, or corroded or damaged connectors, occur. In addition to displaying faults in terms of
distance into the cable or feedline, the magnitude of the fault is also displayed.
Structural return loss is a special case of return loss(reflection) measurements, optimized for measuring
periodic reflections of small magnitude. These periodic reflections can occur from physical damage to the cable
caused by rough handling, or from minor imperfections imparted during the manufacturing process. Structural
return loss problems occur when these periodic reflections sum at half-wavelength intervals, causing high signal
reflection (and low transmission) at the corresponding frequency.
