Keysight 849x and 1158x Operating and Service Manual
Installation
Initial inspection
1
Inspect the shipping container for damage. If the shipping container or cushioning material is
damaged, it should be kept until the contents of the shipment have been checked for
completeness and the instrument has been checked both mechanically and electrically.
– Check for mechanical damage such as scratches or dents.
– Procedures for checking electrical performance are given under “Operator's Check” or
“Performance Tests”.
2
If the contents are incomplete, if there is mechanical damage or defect, or if the instrument
does not pass the electrical performance test, contact the nearest Keysight Technologies Sales
and Service office. Refer to the Service and Support information in the front matter of this
manual. Keysight Technologies will arrange for repair or replacement of the damaged or
defective equipment. Keep the shipping materials for the carrier's inspection.
3
If you are returning the instrument under warranty or for service, repackaging the instrument
requires original shipping containers and materials or their equivalents. Keysight Technologies
can provide packaging materials identical to the original materials. Refer to Service and
Support information in the front matter of this manual for the Keysight Technologies nearest
you. Attach a tag indicating the type of service required, return address, model number, and
serial number. Mark the container
FRAGILE
to insure careful handling. In any correspondence,
refer to the instrument by model number and serial number.
