Connector care and maintenance
How to connect and torque an SMA connector
1 First, ensure that the mating halves of the connector are correctly aligned.
2 Next, engage the threads of the nut and tighten it by hand, ensuring that the mating
halves do not move relative to each other.
3 Then use a torque spanner to tighten the connector, in order to ensure consistent
matching and to avoid mechanical stress.
Torque settings for connectors are:
