Safety Summary
The following general safety precautions must be observed during all phases of operation,
service
,and repair of this instrument. F
ailure to comply with these precautions or with specic
W
ARNINGS
given elsewhere in this manual violates safety standards of design, manufacture,
and intended use of the instrument.
The A
gilent T
echnologies assumes no liability for the customer's failure to comply with these
requirements
.
DO NOT Operate In An Explosive Atmosphere
Do not operate the instrument in the presence of ammable gasses or fumes
.Operation of any
electrical instrument in such an environment constitutes asafety hazard.
K
eep A
way From Live Circuits
Operating personnel must not remove instrument covers
. Component replacement and internal
adjustments must be made by qualied maintenance personnel. Do not replace components
with the power cable connected. Under certain conditions
, dangerous voltages may exist even
with the power cable removed. T
oavoid injuries
,always disconnect power and discharge
circuits before touching them.
DO NOT Service Or A
djust Alone
Do not attempt internal service or adjustment unless another person, capable of rendering rst
aid and resuscitation, is present.
DO NOT Substitute P
arts Or Modify Instrument
Because of the danger of introducing additional hazards
,do not substitute parts or perform
unauthorized modications to the instrument. Return the instrument to aAgilent T
echnologies
Sales and Service Oce for service and repair to ensure the safety features are maintained.
Dangerous Procedure Warnings
Warnings
,suchas the example below
,precede potentially dangerous procedures throughout
this manual. Instructions contained in the warnings must be followed.
Warning
Dangerous voltages
,capable of causing death, are present in this
instrument. Use extreme caution when handling, testing, and adjusting
this instrument.
The voltage levels found in this test xture when used with the intended instruments do not
warrant more than normal safety precautions for operator safety
.
iv

Operating Precaution
Do not exceed the operating input power, voltage, and current level and signal type
appropriate for the instrument being used, refer to your instrument's operation manual.
Caution
Electrostatic discharge (
esd
)candamage the highly sensitive microcircuits in
your instrument. ESD damage is most likely to occur as the test xtures are
being connected or disconnected. Protect them from ESD damage by wearing a
grounding strap that provides ahigh resistance path to ground. Alternatively
,
ground yourself to discharge any static charge built-up by touching the
outer shell of any grounded instrument chassis before touching the test port
connectors
.
Never touch the test clip contacts
.
Use awork station equipped with an anti-static work surface
.
Certication
Agilent T
echnologies certies that this product met its published specications at the time
of shipment from the factory
.Agilent T
echnologies further certies that its calibration
measurements are traceable to the United States National Institute of Standards and
T
echnology
,to the extent allowed by the Institution's calibration facility
,or
to the calibration
facilities of other International Standards Organization members
.

of the instrument, or software
,orrmware will be uninterrupted or error free
.
v

Limitation Of Warranty
The foregoing warranty shall not apply to defects resulting from improper or inadequate
maintenance by Buyer
,Buyer-supplied software or interfacing, unauthorized modication or
misuse
,operation outside the environmental specications for the product, or improper site
preparation or maintenance
.
No other warranty is expressed or implied. A

Safety Symbols
General denitions of safety symbols used on equipment or in manuals.
Instruction manual symbol: the product is marked with this symbol when it is
necessary for the user to refer to the instruction manual in order to protect
against damage to the instrument.
Indicates dangerous voltage (terminals fed from the interior by voltage
exceeding 1000 volts must be so marked).
Protective conductor terminal. F
or protection against electrical shock in case
of afault. Used with wiring terminals to indicate the terminal that must be
connected to ground before operating equipment.
Low-noise or noiseless, clean ground (earth) terminal. Used for asignal
common, as well as providing protection against electrical shock in case of
fault. Aterminal marked with this symbol must be connected to ground in the
manner described in the installation (Operation) manual, and before operating
the equipment.
Frame or chassis terminal. Aconnection to the frame (chassis) of the
equipment which normally includes all exposed metal structures
.
Alternating current (power line).
Direct current (power line).
Alternating or direct current (power line).
W
arning
