SMA Connectors
Inspect and Clean Connectors
Clean connector interfaces prolong connector life and produce more accurate
and repeatable measurements. When using SMA female connectors, pay special
attention to the contact fingers on the female center conductor. These can be
bent or broken, and damage to them is not always easy to see. A connector with
damaged contact fingers will not make good electrical contact and must be
repaired or replaced.
Inspect each connector to make sure that no particles or residue are present.

Always use protective eye-wear when using compressed air or
nitrogen.
Keep isopropyl alcohol away from heat, sparks, and flame.
Store in a tightly closed container. Isopropyl alcohol is
extremely flammable. In case of fire, use alcohol foam, dry
chemical, or carbon dioxide; water may be ineffective.
Use isopropyl alcohol with adequate ventilation and avoid
contact with eyes, skin, and clothing. It causes skin
irritation, may cause eye damage, and is harmful if
swallowed or inhaled. It may be harmful if absorbed
through the skin.
Wash thoroughly after handling. In case of spill, soak up
with sand or earth. Flush spill area with water.
Dispose of isopropyl alcohol in accordance with all
applicable federal, state, and local environmental
regulation.
– Use compressed air to loosen particles on the connector mating plane
surfaces.
– Apply a small amount of isopropyl alcohol to a lint-free swab. Clean the
connector threads. Let the alcohol evaporate, then blow the threads dry
with a gentle stream of clean, low-pressure compressed air or nitrogen.
Always completely dry a connector before you reassemble or use it.
