Installation
Initial Inspection Inspect the shipping container for damage. If the shipping container or
cushioning material are damaged, they should be kept until the contents of
the shipment have been checked for completeness and the instrument has
been checked mechanically and electrically. A procedure for checking
electrical performance is provided under “Operator’s Check” on page 8 (see
also “Performance Tests” on page 9).
If the contents of the shipment are incomplete, or if there is mechanical
damage or defect, or if the instrument does not pass the electrical
performance test, notify the nearest Agilent Technologies office. If the
shipping container is damaged, or the cushioning material shows signs of
stress, notify the carrier as well as the Agilent Technologies office. Keep the
shipping materials for the carrier's inspection. The Agilent office will
arrange for repair or replacement without waiting for claim settlement.
NOTE Containers and materials identical to those used in factory packaging are
available through Agilent Technologies offices. If the instrument is being
returned to Agilent for servicing, attach a tag indicating the type of service
required, return address, model number, and full serial number. Also, mark
the container FRAGILE to assure careful handling. In any correspondence,
refer to the instrument by model number and full serial number.
Mating Connectors Mating connectors used with the Option 001 must be type-N male
connectors, which comply with U.S. military standard MIL-C-39012. For
Option 002, male SMA connectors must be used. For Option 003, APC-7
mating connectors must be used.
CAUTION When installing the instrument, make sure that the connectors do not support
weight or bear torque. The preferred procedure is to set up all equipment in
position before connecting the instrument. Either connector may be used as
the input or output connector.
Installing with Base The attenuators may be installed with or without the base. The base is
removed by unscrewing the two fillister head screws from the bottom of the
base. The attenuator may be mounted without the base by inserting two 4-40
screws into the screw holes in the bottom of the attenuator. Removing the
base and mounting the attenuator does not affect the performance of the
attenuator.
