WARNINGS
The following general safety precautions must be observed during all phases of operation, service, and
repair of this product. Failure to comply with these precautions or with specific warnings elsewhere in this
manual violates safety standards of design, manufacture, and intended use of the product. Agilent Technologies assumes no liability for the customer's failure to comply with these requirements.
This is a safety Class 1 instrument (provided with a protective earthing ground, incorporated in the powercord). The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. Any
interruption of the protective conductor inside or outside of the instrument is likely to make the instrument
dangerous. Intentional interruption is prohibited.
DO NOT operate the product in an explosive atmosphere or in t he presence of flammable gasses or fumes.
For continued protection against fire hazard, replace the line fuses only with the same type and ratings (see
.Fuse Ratings on page 2-10). The use of other fuses or materials is prohibited.
Keep away from live circuits: Operating personnel must not remove equipment covers or shields. Proce-
dures involving the removal of covers and shields are for use by service-trained personnel only. Under certain conditions, dangerous voltages may exist even with the equipment switched off. To avoid dangerous
electrical shock, DO NOT perform procedures involving cover or shield removal unless you are qualified to
do so.
DO NOT operate damaged equipment: Whenever it is possible that the safety protection features built into
this product have been impaired, either through physical damage, excessive moisture, or any other reason,
REMOVE POWER and do not use the product until safe operation can be verified by service-trained personnel. If necessary, return the product to an Agilent Technologies Sales and Service Office for service and
repair to ensure the safety features are maintained.
DO NOT service or adjust alone: Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present.
DO NOT substitute parts or modify equipment: Because of the danger of introducing additi onal hazards, do
not install substitute parts or perform any unauthorized modification to the product. Return the product to an
Agilent Technologies Sales and Service Office for service and repair to ensure the safety features are maintained.
If this instrument is not used as specified, the protection provided by the equipment could be impaired. This
instrument must be used in a normal condition (in which all means of protection are intact) only.
No operator serviceable parts inside. Refer servicing to qualified personnel. To prevent electrical shock do
not remove covers.

Safety Considerations
This product is a Safety Class 1 instrument (provided with a protective earth terminal).
The instrument and manual should be reviewed for safety markings and instructions
before operation. Also read the Warnings page at the front of this manual
Safety Information
The following general safety precautions must be observed during all phases of operation,
service, and repair of this instrument. Failure to comply with these precautions or with
specific warnings elsewhere in this manual violates safety standards of design,
manufacture, and intended use of the instrument. Agilent Technologies Company assumes
no liability for the customer's failure to comply with these requirements.

General Information
Safety Considerations
While this is a Class I product, provided with a protective earthing conductor in a
powercord, an external protective earthing terminal has also been provided in later
models. This terminal (shown in the photograph below) is for use where the earthing
cannot be assured. At least an 18AWG earthing conductor should be used in such an
instance, to ground the instrument to an assured earth terminal.
General
DO NOT operate the product in an explosive atmosphere or in the presence of flammable
gasses or fumes.
DO NOT use repaired fuses or short-circuited fuseholders. For continued protection
against fire, replace the line fuse(s) only with fuse(s) of the same voltage and current
rating and type.
DO NOT perform procedures involving cover or shield removal unless you are qualified
to do so. Operating personnel must not remove equipment covers or shields. Procedures
involving the removal of covers and shields are for use by service-trained personnel only.
DO NOT service or adjust alone. Under certain conditions, dangerous voltages may exist
even with the equipment switched off. To avoid dangerous electrical shock, service
personnel must not attempt internal service or adjustment unless another person, capable
of rendering first aid and resuscitation, is present.
DO NOT operate damaged equipment. Whenever it is possible that the safety protection
features built into this product have been impaired, either through physical damage,
excessive moisture, or any other reason, REMOVE POWER and do not use the product
until safe operation can be verified by service-trained personnel. If necessary, return the
product to an Agilent Technologies Sales and Service Office for service and repair to
ensure the safety features are maintained.
DO NOT substitute parts or modify equipment. Because of the danger of introducing
additional hazards, do not install substitute parts or perform any unauthorized
modification to the product. Return the product to an Agilent Technologies Sales and
Service Office for service and repair to ensure the safety features are maintained.

necessary for the user to refer to the instructions in the supplied documentation.
Alternating current (AC)
Indicates the field wiring terminal that must be connected to earth ground before operating
the equipment - protects against electrical shock in case of faul t . See Page 1-3 for further
details.
This symbol indicates the position of the operating switch for ‘On’ mode .

CAUTION
This symbol indicates the position of the operating switch for ‘Off’ mode.
This symbol indicates the position of the opera ti ng switch for ‘Stand -b y’ mode . Note, the
instrument is NOT isolated from the mains when the switch is in this position.
To isolate the instrument, the mains coupler (mains input cord) should be removed from the
power supply.
This symbol represents the ‘IN‘ position of a bi-stable push-button switch.
This symbol represents the ‘OUT‘ position of a bi-stable push-button switch.
Warning denotes a hazard. It calls attention to a pro ced ur e, which if not corr ectly performed or adhered to could result in injury or loss of life. Do not proceed beyond a warning
note until the indicated conditions are fully understood and met.
Caution denotes a hazard. It calls attention to a procedure, which if not correctly performed
or adhered to could r esult in damage to or destr uction of the instr ument. Do not proceed

Introduction
The Agilent 12.5 Gb/s BERT products offer a range of product options to suit user
applications. There are two standard core products (Agilent 71612 and Agilent 70843)
each having a set of user options. The core products cannot be ordered or supplied on their
own; they must be ordered with an option. They are as follows:
• Agilent 71612: comprises an Agilent 70004A display and an Agilent 70843 product
base.
• Agilent 70843: comprises an Agilent Technologies MMS system II cabinet with
PSU and control hardware/firmware functions for a BERT, pattern generator or error
detector option. Agilent 70843 options are provided for users who may not require
an Agilent 70004A display or who wish to operate the instrument remotely via
GPIB.
The following tables list the options available for the Agilent 71612 and Agilent 70843
core products.
