Taking Care Of Microwave Connectors - Agilent Technologies 8719ES User Manual

Taking Care of Microwave Connectors

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.
This type of information is typically located in chapter 3 of the calibration kit manuals.
For additional connector care instruction, contact your local Agilent Technologies Sales
and Service Office about course numbers HP/Agilent 85050A+24A and 85050A+24D.
See the following table for quick reference tips about connector care.
