Caring for Connectors

Introduction

Introduction
Recent advances in measurement capabilities have made connectors and
connection techniques more important than ever before. Damage to the
connectors on calibration and verification devices, test ports, cables, and
other devices represent an increasing burden in downtime and expense.
This Appendix will help you get the best performance from all coaxial
microwave connectors:
• To know what to look for when cleaning and inspecting them, in order
to preserve their precision and extend their life.
• To make the best possible microwave connections, improving the
accuracy and repeatability of all of your measurements, saving both
time and money.
Connector Part Numbers
Refer to the latest edition of the HP RF and Microwave Test Accessories
Catalog for connector part numbers.
Handling and Storage
Microwave connectors must be handled carefully, inspected before use
and when not in use, stored in a way that gives them maximum
protection. Avoid touching the connector mating plane surfaces and
avoid setting the connectors contact-end down, especially on a hard
surface.
Never store connectors with the contact end exposed. Plastic end caps
are provided with all Agilent connectors and these should be retained
after unpacking and placed over the ends of the connectors whenever
they are not in use. Extend the threads of connectors that have a
retractable sleeve or sliding connector nut, then put the plastic end cap
over the end of the connector.
Above all, never store any devices loose in a box or in a desk or a bench
drawer. Careless handling of this kind is the most common cause of
connector damage during storage.
