Info

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. This type of information is typically located in Chapter 3 of the calibration kit manuals For additional connector care instruction, contact your local Hewlett-Packard Sales and Service Office about course numbers HP 8505OA + 24A and HP 8505OA + 24D. See the following table for quick reference tips about connector care. Service Equipment and Analyzer Options l-5
