About this Manual
We’ve added this manual to the Agilent website in an effort to help you support
your product. This manual is the best copy we could find; it may be incomplete
or contain dated information. If we find a more recent copy in the future, we will
add it to the Agilent website.
Support for Your Product
Agilent no longer sells or supports this product. Our service centers may be able
to perform calibration if no repair parts are needed, but no other support from
Agilent is available. You will find any other available product information on the
Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

Safety
Considerations GENERAL
This product and related documentation must be reviewed for familiar-
ization with safety markings and instructions before operation.
This product is a Safety Class I instrument (provided with a protective
earth terminal).
SAFETY EARTH GROUND
A unterruptible safety earth ground must be provided from the main
power source to the product input wiring terminals, power cord, or sup-
plied power cord set.
CHASSIS GROUND TERMINAL
To prevent a potentialshock hazard, always connect the rear-panel chas-
sis ground terminalto earth ground whenoperating this instrument from
a dc power source.
SAFETY SYMBOLS
Indicates instrument damage can occur if indicated operating limits are
exceeded.
Indicates hazardous voltages.
Indicates earth (ground) terminal
WARNING A WARNING note denotes a hazard. It calls attention to a
procedure, practice, or the like, which, if not correctly performed
or adhered to, could result in personal injury. Do not proceed
beyond a WARNING sign until the indicated conditions are fully
understood and met.

CAUTION A CAUTION note denotes a hazard. It calls attentionto an operation
procedure, practice, or the like, which, if not correctly performed or
adhered to, could result in damage to or destruction of part or all of
the product. Do not proceed beyond an CAUTION note until the
indicated conditions are fully understood and met.
Safety Considerations for this Instrument
WARNING Any interruption of the protective (grounding) conductor (inside
or outside the instrument) or disconnection of the protective
earth terminal will cause a potential shock hazard that could
result in personal injury. (Grounding one connector of a two
conductor outlet is not sufficient protection.)
Whenever it likely that the protection has been impaired, the
instrument must be made inoperative and be secured against any
unintended operation.
If this instrument is to be energized via an auto transformer (for
voltage reduction), make sure the common terminal is connected
to the earth terminal of the power source.
Servicing instructions are for use by service trained personnel
only. To avoid dangerous electric shock, do not perform any
servicing unless qualified to do so.
Adjustments described in the manual are performed with power
supplied to the instrument while protective covers are removed.
Energy available at many points may, if contacted, result in
personal injury.
Capacitors inside the instrument may still be charged even if the
instrument has been disconnected from its source of supply.
For Continued protection against fire hazard, replace the line
fuse(s) only with 250 V fuse(s) or the same current rating and
type (for example, normal blow or time delay). Do not use
repaired fuses or short circuited fuseholders.
