Keysight 81618A/9A and Keysight 81620B/3B/4B/6B/8B Optical Heads User's Guide
Applicable to Keysight 81628B only.
Operation above 34 dBm (2.51 W) is at your own risk.
Operation at a continuous optical power, or an average optical power,
greater than 34 dBm causes, in the specified operating temperature
range, the metal parts (connector adapters, screws) to become hotter
than the required limit (55°C) of the safety standard IEC 61010- 1.
Keysight Technologies Deutschland GmbH will not be liable for any
damage caused by operation above 34 dBm.
Inspect the shipping container for damage. If there is damage to the
container or cushioning, keep them until you have checked the contents of
the shipment for completeness and verified the instrument both
mechanically and electrically.
The Performance Tests give procedures for checking the operation of the
instrument. If the contents are incomplete, mechanical damage or defect
is apparent, or if an instrument does not pass the operator's checks, notify
the nearest Keysight Technologies Sales/Service Office.
To avoid hazardous electrical shock, do not perform electrical tests when
there are signs of shipping damage to any portion of the outer enclosure
(covers, panels, etc.).
