Use, Maintenance, and Care of the Devices
Visual Inspection

Visual Inspection
Visual inspection and, if necessary, cleaning should be done every time a
connection is made. Metal particles from the connector threads may fall into
the connector when it is disconnected.
Magnification is helpful when inspecting connectors, but it is not required and
may actually 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.
Look for Obvious Defects and Damage First
Examine the connectors first for obvious defects or damage: badly worn
plating on the connector interface, deformed threads or bent, broken, or
misaligned center conductors. Connector nuts should move smoothly and be
free of burrs, loose metal particles, and rough spots.
What Causes Connector Wear?
Connector wear is caused by connecting and disconnecting the devices. The
more use a connector gets, the faster it wears and degrades. The wear is
greatly accelerated when connectors are not kept clean, or are not connected
properly.
Connector wear eventually degrades performance of the device. Verification
devices should have a long life if their use is on the order of a few times per
week. Replace devices with worn connectors.
The test port connectors on the PNA test set may have many connections each
day, and are, therefore, more subject to wear. It is recommended that an
adapter be used as a test port saver to minimize the wear on the test set’s test
port connectors.
Obvious Defects or Damage
Examine the connectors first for obvious defects or damage:
— Plating
— Bare metal showing
— Burrs or blisters
— Deformed threads
Devices with damaged connectors should be immediately discarded or
clearly marked and set aside for repair. A damaged device will in turn
damage any good connector to which it is attached. Determine the cause
of the damage before connecting a new, undamaged connector in the
same configuration.
