Cable Preparation Problems
Follow the preparation instructions provided by the connector
manufacturer and take great care to avoid the following cable
preparation problems:
• bent cable
• deformed cable
• contaminated dielectric
• damaged outer conductor
• non-flush cut
Bent Cable
Poor measurement results can occur if the cable is bent or kinked near
the end of the spool. See Figure 2-1 and Figure 2-2.
Figure 2-1 Bent/Kinked Cable
The upper trace in Figure 2-2 is an SRL measurement. The lower trace is
a fault location measurement showing the connector at 0.0 ft and the
first 15 ft of the cable. The multiple bumps in the SRL response indicate
the likelihood of multiple cable faults. The fault location response shows
two significant bumps at 0.0 ft and at 1.5 ft. The bump at 1.5 ft is a
response from the bend in the cable. The bend should be removed before
proceeding with the SRL measurement.
