Repeatability
If two identical measurements are made with the tester,
the differences in the measured data should be so small
that they do not affect the value of the measurement.
Connector repeatability may be a cause of poor
measurement results. Connector repeatability problems
may be affected by:
• Dirty or damaged connectors
• Connections that have been made without using
proper torque techniques (this applies when
connections to the tester have been removed, then
reconnected).
Extending the life of your cables and
connectors
• Minimize the bending of test cables. A single sharp
bend can damage a RF cable.
• Avoid repeated connection and disconnection of all
RF cable connections.
• Do not bend cables at or near the RF connectors. This
may affect the RF performance.
• Inspect all connectors for dirt, nicks, and other signs
of damage or wear before connection. A bad
connector can ruin a good connector instantly.
• Clean dirty connectors. Dirt and foreign matter can
cause poor electrical connections, affect RF
measurements, and may permanently damage the
connectors.
Never exceed the recommended connector torque values
