Connectors
Taking proper care of cables and connectors will protect the ability of
your analyzer to make accurate measurements. Inaccurate
measurements often result from improperly made connections or dirty
or damaged connectors. Worn, out-of-tolerance, or dirty connectors
degrade the accuracy and repeatability of measurements.
Repeatability
If you make two identical measurements with your analyzer, the
differences should be so small that they do not affect the value of the
measurement. Repeatability (the amount of similarity from one
measurement to another of the same type) can be affected by:
• Dirty or damaged connectors
• Connections that have been made without using proper torque
techniques (this applies primarily when connectors in the analyzer
have been disconnected, then reconnected)
CAUTION This analyzer contains devices that are static-sensitive. Always take
proper electrostatic precautions before touching the center conductor of
any connector, or the center conductor of any cable that is connected to
the analyzer.
RF Cable and Connector Care
Connectors are the most critical link in a precision measurement. These
devices are manufactured to extremely precise tolerances and must be
used and maintained with care to protect the measurement accuracy
and repeatability of your analyzer.
To Extend the Life of Your Cables or Connectors:
• Avoid repeated bending of cables—a single sharp bend can ruin a
cable instantly.
• Avoid repeated connection and disconnection of cable connectors.
• Inspect the connectors before connection; look for dirt, nicks, and
other signs of damage or wear. A bad connector can ruin the good
connector instantly.
• Clean dirty connectors. Dirt and foreign matter can cause poor
electrical connections and may damage the connector.
• Minimize the number of times you bend cables.
