Connecting RF Cables
Many
are desigened for connecting test equipment via RF cables.
Excessive tightening of coaxial RF connections can damage the connectors of both
cables and modules. Too weak tightening leads to inaccurate measurement results.
Connecting RF cables / TORQUE RECOMMENDATIONS
For best connections, proceed as follows:
1. Carefully
align
the connectors along a common axis.
2. Mate the connectors along the common axis until the male pin of the inner connec-
tor engages with the female socket of the outer connector.
3. When fastening the connectors,
only turn the nut
of the outer connector until the
connectors are firmly coupled.
Avoid rotating the body of the outer connector.
4. If the inner connector is on a cable, hold it stationary with a spanner.
5. For fastening the connection, use a calibrated
torque wrench
suitable for the con-
nector type.
Never use a standard open-end wrench.
6. Fasten the nut of the outer connector to the specified torque limit.
For specifications, refer to
application note 1MA99
