Look for metal particles from the connector threads and other signs of wear
(such as discoloration or roughness). Visible wear can affect measurement
accuracy and repeatability. Discard or repair any device with a damaged
connector. A bad connector can ruin a good connector on the first mating. A
magnifying glass or jeweler's loupe is useful during inspection.
Use caution when mating SMA connectors to any precision 2.4 mm or 3.5
mm RF connector. SMA connectors are not precision devices and are often
out of mechanical tolerances, even when new. An out-of-tolerance SMA
connector can ruin a 2.4 mm or 3.5 mm connector on the first mating. If in
doubt, gauge the SMA connector before connecting it. The SMA center
conductor must never extend beyond the mating plane.
1. Blow particulate matter from connectors using an environmentally-safe
aerosol such as Ultrajet. This product is recommended by the United
States Environmental Protection Agency and contains
chlorodifluoromethane. You can order this aerosol from Agilent
Technologies (see Table
2. Use an alcohol wipe to wipe connector surfaces. Wet a small swab with
alcohol (from the alcohol wipe) and clean the connector with the swab.
3. Allow the alcohol to evaporate off the connector before making
connections
