Dear Customer,
As of November 1,1999, four of Hewlett-Packard'sbusinesses,test and measurement,
semiconductor products,healthcare solutions, and chemical analysis became a new company,
Agilent Technologies. Now, many of your Hewlett-Packardproductsand services are in the care of
Agilent Technologies.
At Agilent Technologies, we are working diligentlyto makethis transition as smooth as possiblefor
you. However,as a result of this transition, the products and related documentationcontained in this
shipment may be labeledwith either the Hewlett-Packardname and logo, the Agilent Technologies
name and
logo, or a combinationof both. Information in this package may refer to Hewlett-Packard

For Continuedprotectionagainstfirehazard,replacethe line fuse@)
only with
250 V fuse(s) or the same current rating and type (for
example, normalblow
or time delay).Do not use repaired fusesor
short circuited fuseholders.
Always use the three-prongac power cordsuppliedwith this
product. Failure
to ensure adequate earth groundingby not using
this cord may causeproduct damage.
Thisproduct is designed foruse in Installation Category I1 and
Pollution Degree 2 per ZEC 1010 and ZEC 664 respectively. FOR
INDOOR USE ONLY.
This product has autoranginglinevoltageinput,be surethe supply

To prevent electricalshock,disconnect instrument from mains (line)
before cleaning.
Use a dry cloth or one slightly dampenedwith water
to clean the externalcaseparts.
Do not attemptto clean internally.
VentilationRequirements:When installingthe product in a cabinet,
the convectioninto and out of theproduct must not be restricted.
The ambient temperature (outsidethe cabinet)must be less than the
maximum operatingtemperature
of theproduct by 4" C for every 100
watts dissipated in the cabinet. If thetotal power dissipated in the
cabinet is greater than
800 watts, then forced convectionmust be
used.

SAFETY CONSIDERATIONS
GENERAL
This product and related documentation must be re-
viewed for familiarization with safety markings and
instructions before operation.
This product is a Safety Class I instrument (provided
with a protective earth terminal).
BEFORE APPLYING POWER
Verify that the product is set to match the available
line voltage and the correct fuse is installed.
SAFETY EARTH GROUND
An uninterruptible safety earth ground must be pro-
vided from the main power source to theproduct input
wiring terminals, power cord,
or supplied power cord
set.
SAFETY SYMBOLS
Instruction manual symbol: the product will
A be marked with this symbol when it
is necessary for the user to refer to the instruction
manual (refer to Table of Contents).
Indicates hazardous voltages.
Indicates earth (ground) terminal.
f
VI
The WARNING sign 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 in-
jury.
Do not proceed beyond a WARNING sign until
the indicated conditions arefully understood and met.
TheCAUTION sign denotes a haz-
ard. It calls attention to an
operating procedure, practice, or the like,which, if not
correctly performed or adhered to,could result in dam-
age to
or destruction of part or all of the product. Do
not proceed beyond a CAUTION sign until the indi-
cated conditions are fully understood and met.
Any interruption of the protective (ground-
ing) conductor (inside
or outside the instru-
ment)
or disconnecting the protective earth
terminal will came a potential shock hazard
that could result
in personal injury. (Ground-
ing one conductor of a two conductor outlet
is not sufficient protection).
Whenever it is likely that the protection has
been impaired, the instrument must be made
inoperative and be secured against any unin-
tended operation.
If this instrument is to be energized via an
autotransformer (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 areper-
formed withpower supplied to the instrument
while protective covers are removed. Energy
available at manypoints may, ifcontacted, re-
sult
in personal injury.
Capacitors inside the instrument may still be
charged even
if the instrument has been dis-
connected from its source of supply.
For continued protection against fire hazard,
replace the line fuse(s)only with
250V fuse(s)
of the same current rating and type (forexam-
ple, normal blow, time delay, etc.).
Do not use
repaired fuses
or short circuited
fuseholders.

ATTENTION
Static Sensitive
Devices
This instrument was constructed in an ESD (electro-static dis-
charge) protected environment. This
is because most of the semi-
conductordevices used
in this instrument are susceptible todamage
by static discharge.
Depending on the magnitude of the charge, device substrates can
be punctured
or destroyed by contact or mere proximity of a static
charge. The results can cawe degradation of device performance,
early failure, or immediate destruction.
These charges are generated in numerous ways such as simple con-
tact, separation
of materials, and normal motions of persons
working with static sensitive devices.
Whenhandling or servicing equipment containing static sensitive
devices, adequate precautions must be taken toprevent device dam-
age
or destruction.
Only those who are thoroughly familiar with industry accepted
techniques for handling static sensitive devices should attempt to
service circuitry with these devices.
In all instances, measures must be taken to prevent static charge
build-up
on work surfaces and persons handling the devices.
For further information on ESD precautions, refer to “SPECIAL
HANDLING CONSIDERATIONS FOR STATIC SENSITIVE
DEVICES” in Section VIII Service Section.

Thisproduct is a SafetyClass I instrument, that is, one provided with a protective earth terminal. The
Multifunction Synthesizer and
all related documentation must be reviewed for familiarization with
safety markings and instructions before operation. Refer to the Safety Considerations pages found at
the beginning of this manual for a summary of the safety information. Safety information pertinent
to the
task at hand, that is, installation, operation, performance testing, and adjustments, is found
throughout this manual.
1-3. DESCRIPTION
The HP 8904A is a Multifunction Frequency Synthesizer that produces six fundamental waveforms
to create complex signals. The waveforms available are: dc, sine wave, ramp (sawtooth), triangle,
square wave, and white (Gaussian) noise. The standard instrument is equipped with a single internal
channel
and one output. The addition of available options can provide: a second signal output port,
three additional internal channels with modulation capabilities, and the ability to fast-hop between
different phase, frequency, and amplitude settings. Multi-instrument synchronization and high level
balanced output are also available.
A description of the available options is given in paragraphs 1-6 and 1-7.
