Getting Started
Connector Care
3. Add a few drops of high-purity isopropyl alcohol to a small cleaning swab
(do not apply alcohol directly to the parts).
4. Gently wipe connecting surfaces with the end of the cleaning swab.
5. Blow dry with compressed air.
6. Inspect and repeat cleaning procedure if necessary.
Visual Inspection
Visual inspection and, if necessary, cleaning should be done every time a
connection is made. Metal particles from connector threads may fall into the
connector when it is disconnected. One connection made with a dirty or
damaged connector can damage both connectors beyond repair.
Magnification is helpful when inspecting connectors, but it is not required and
may be misleading. Defects and damage that cannot be seen without
magnification generally have no effect on electrical or mechanical
performance. Magnification is of great use in analyzing the nature and cause of
damage and in cleaning connectors, but it is not required for inspection.
Obvious defects or damage
Examine the connectors first for obvious defects or damage:
1. Plating
— Bare metal showing
2. Burrs or blisters
3. Deformed threads
4. Center conductors
— Bent
— Broken
— Misaligned
— Concentricity
5. Connector nuts should move smoothly and be free of:
— Burrs
— Loose metal particles
When using isopropyl alcohol to clean connectors do not allow the liquid
to flow down Keysight U9361 RCal Receiver Calibrator inside the
connector. This may cause measurement errors due to residue inside the
connector. If possible, keep the connector downward facing.
