Care and Maintenance
Disconnect the Keysight U9361C/F/G/M from USB power before cleaning.
Use a dry cloth or one slightly dampened with water to clean the external
case parts. Do not attempt to clean internally.
The U9361C/F/G/M receiver calibrator is not field-repairable, and requires
return to Keysight for both repair and calibration. Do not attempt to open
the instrument enclosure.
Connector Care
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 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.
Obvious defects or damage
Examine the connectors first for obvious defects or damage:
Plating
— Bare metal showing
— Burrs or blisters
Deformed threads
Center conductors
— Bent
— Broken
— Misaligned
— Concentricity
Connector nuts should move smoothly and be free of:
— Burrs
— Loose metal particles
— Rough spots
Any connector that has obvious defects should be replaced.
