Keysight M9383B Microwave Signal Generator Security Guide

Safety Information
Do not exceed the maximum signal levels of the instruments and accessories, as defined in the
specifications and operating information, and as shown on the instrument or test fixture panels,
or switching card.
When fuses are used in a product, replace with the same type and rating for continued
protection against fire hazard.
Chassis connections must only be used as shield connections for measuring circuits, NOT as
safety earth ground connections.
If you are using a test fixture, keep the lid closed while power is applied to the device under
test. Safe operation requires the use of a lid interlock.
Instrumentation and accessories shall not be connected to humans.
Before performing any maintenance, disconnect the line cord and all test cables.
To maintain protection from electric shock and fire, replacement components in mains circuits -
including the power transformer, test leads, and input jacks - must be purchased from
Keysight. Standard fuses with applicable national safety approvals may be used if the rating
and type are the same. Other components that are not safety related may be purchased from
other suppliers as long as they are equivalent to the original component (note that selected
parts should be purchased only through Keysight to maintain accuracy and functionality of the
product). If you are unsure about the applicability of a replacement component, call an Keysight
office for information.
No operator serviceable parts inside. Refer servicing to qualified personnel. To prevent
electrical shock do not remove covers. For continued protection against fire hazard, replace
fuse with same type and rating.
