which is not customer accessible.
Do Not Operate in an Explosive
Atmosphere
Do not operate the instrument in the
presence of flammable gases or fumes.
Do Not Remove the Instrument
Cover
Only qualified, service-trained personnel
who are aware of the hazards involved
should remove instrument covers. Always
disconnect the power cable and any
external circuits before removing the
instrument cover.

Do not install substitute parts or perform
any unauthorized modification to the
product. Return the product to an Agilent
Sales and Service Office for service and
repair to ensure that safety features are
maintained.
In Case of Damage
Instruments that appear damaged or
defective should be made inoperative and
secured against unintended operation
until they can be repaired by qualified
service personnel.
A CAUTION notice denotes a hazard.
It calls attention to an operating
procedure, practice, or the like that, if
not correctly performed or adhered to,
could result in damage to the product
or loss of important data. Do not
proceed beyond a CAUTION notice
until the indicated conditions are fully
understood and met.
A WARNING notice denotes a
hazard. It calls attention to an
operating procedure, practice, or the
like that, if not correctly performed
or adhered to, could result in

The Agilent N6700 Modular Power System – At a Glance
The Agilent N6700 Modular Power System is a configurable, one rack-
unit (1U) platform that lets you mix and match power modules to
create a power system optimized for your test system requirements.
Agilent N6700–N6702 MPS mainframes are available in power levels
of 400 W, 600 W, and 1,200 W. Up to four power modules can be
installed in each mainframe. Power modules come in power levels of
20 W through 500 W, have various voltage and current combinations,
and provide the following performance features:
The N673xB, N674xB, and N677xA DC Power Modules provide
programmable voltage and current, measurement, and protection
features, making these economical models suitable for powering
the device-under-test or system resources such as fixture controls.
The N675xA High-Performance, Autoranging DC Power Modules
provide low noise, high accuracy, fast programming times, and
advanced programming and measurement capabilities to speed
test throughput.
The N676xA Precision DC Power Modules provide precise control
and measurements in the milli- and micro-ampere region with
the ability to simultaneously digitize voltage and current and
capture those measurements into an oscilloscope-like data buffer.
The N678xA Source/Measure Units (SMU) have a multiple-
quadrant power mesh with separate voltage and current priority
source modes. These models are optimized for applications such
as battery drain analysis and functional testing.
The N6783A Application-Specific DC Power Modules are two-
quadrant low-wattage models specifically designed for battery
charging/discharging and mobile communications applications.
The output and system features are described in the following
sections. Not all output features are available on every power
module. The “Model Differences” section describes the features that
apply only to specific power modules.
