Principles of Microwave Connector Care
Proper connector care and connection techniques are critical for accurate, repeatable
measurements.
Refer to the calibration kit documentation for connector care information. Prior to making
connections to the network analyzer, carefully review the information about inspecting,
cleaning, and gaging connectors.
Having good connector care and connection techniques extends the life of these devices. In
addition, you obtain the most accurate measurements.
For additional connector care instruction, contact the nearest Agilent Technologies sales or
service office about course numbers HP/Agilent 24A and 24D.
See the following table for quick reference tips about connector care.

Use isopropyl alcohol Get liquid into plastic support beads
Clean connector threads
Gaging Connectors
Do Clean and zero the gage before use Do Not Use an out-of-spec connector
Use the correct gage type
Use correct end of calibration block
Gage all connectors before first use
Making Connections
Do Align connectors carefully Do Not Apply bending force to connection
Make preliminary connection lightly Over tighten preliminary connection
Turn only the connector nut Twist or screw any connection
