Storage and shipment
Original packaging
Containers and materials identical to those used in factory packaging are
available through Keysight Technologies offices. If the instrument is being
returned to Keysight Technologies for servicing, attach a tag indicating the type of
service required, return address, model number, and serial number.
Also, mark the container FRAGILE to assure careful handling. In any
correspondence, refer to the instrument by model number and serial number.
Operation
Operation precautions
If the following energy and power levels are exceeded, the power meter system
may be damaged.
a Maximum Average Power: 200 mW (+23 dBm)
b Maximum Peak Power: 200 mW (+23 dBm)
Maximum torque at the connector should not exceed 12 in-lb (135 Ncm) for the
Type-N connector, or 8 in-lb (90 Ncm) for the 3.5-mm connector to avoid damage
to the connector.
Connect the power sensor by turning only the hex nut portion of the connector.
Damage can occur if torque is applied to the power sensor body.
The connector plastic insulator bead deteriorates when contacted by acetone,
trichloroethylene, carbon tetrachloride, benzene, etc. Refer to Application Note
326, Principals of Microwave Connector Care (5954-1566) or Microwave
Connector Care (08510-90064) for proper cleaning methods.
BEFORE CONNECTING THE POWER SENSOR TO OTHER INSTRUMENTS,
ensure that all instruments are connected to the protective (earth) ground.
Any interruption of the protective earth grounding will cause a potential
shock hazard that could result in personal injury and cause damage to the
power sensor.
