Cleaning Connectors
1. Use Compressed Air or Nitrogen
Clean connectors are essential for ensuring the integrity of RF and microwave coaxial connections.
WARNING Always use protective eyewear when using compressed air or nitrogen.
Use compressed air (or nitrogen) to loosen particles on the connector mating plane surfaces.
You can use any source of clean, dry, low-pressure compressed air or nitrogen that has an effective
oil-vapor filter and liquid condensation trap placed just before the outlet hose.
Ground the hose nozzle to prevent electrostatic discharge, and set the air pressure to less than 414 kPa
(60 psi) to control the velocity of the air stream. High-velocity streams of compressed air can cause
electrostatic effects when directed into a connector. These electrostatic effects can damage the device.
Refer to "Electrostatic Discharge" on page 3-2
2. Clean the Connector Threads
WARNING Keep isopropyl alcohol away from heat, sparks, and flame. Store in a tightly closed
container. It 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 regulations.
Use a lint-free swab or cleaning cloth moistened with isopropyl alcohol to remove any dirt or stubborn
contaminants on a connector that cannot be removed with compressed air or nitrogen. Refer to
on page 6-3 for a part number for cleaning swabs.
a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab.
b. Clean the connector threads.
