Safety Notices
The following general safety precautions
must be observed during all phases of
operation of this instrument. Failure to
comply with these precautions or with
specific warnings or instructions
elsewhere in this manual violates safety
standards of design, manufacture, and
intended use of the instrument. Agilent
Technologies assumes no liability for the
customer's failure to comply with these
requirements.
General
Do not use this product in any manner
not specified by the manufacturer. The
protective features of this product may be
impaired if it is used in a manner not
specified in the operation instructions.
Before Applying Power
Verify that all safety precautions are
taken. Make all connections to the unit
before applying power. Note the
instrument's external markings described
under "Safety Symbols"
Ground the Instrument
This product is a Safety Class 1
instrument (provided with a protective
earth terminal). To minimize shock
hazard, the instrument chassis and cover
must be connected to an electrical
ground. The instrument must be
connected to the AC power mains
through a grounded power cable, with the
ground wire firmly connected to an
electrical ground (safety ground) at the
power outlet. Any interruption of the
protective (grounding) conductor or
disconnection of the protective earth
terminal will cause a potential shock
hazard that could result in personal injury.
Load Connections
Power supplies can output high currents
and high voltages. Make sure that the
load or device under test can safely
handle the output current and voltage.
Also, make sure that the connection
leads can safely withstand the expected
currents and are insulated for the
expected voltages.
Power supply outputs may be connected
so as to float relative to earth ground.
Isolation or floating voltage ratings are
indicated on the instrument, near the
output connectors (see example below).
Do not float the power supply output on
the line-voltage mains. Observe all safety
markings and protection limits.
Fuses
The instrument contains an internal fuse,
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 Modify the Instrument
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.
Cleaning
Clean the outside of the instrument with
a soft, lint-free, slightly dampened cloth.
Do not use detergent or solvents.

1 Quick Reference
12 Model N6705 User’s Guide
The Agilent N6705 DC Power Analyzer – At a Glance
The Agilent N6705 DC Power Analyzer is a multi-functional power
system that combines the functions of a multiple-output DC voltage
source with the waveform/data capturing capability of an
oscilloscope and data logger.
As a multiple-output DC source, the Agilent N6705 provides up to
four configurable outputs. Available power modules have power
levels of 20 W through 500 W, have various voltage and current
combinations, and provide a variety of performance features as
described under “Power Module Capabilities”. Each output also has
arbitrary (Arb) waveform generation capability, which lets you
program predefined voltage and current waveforms – or define your
own waveforms. Agilent N678xA Source/Measure Units (SMU) have a
multiple-quadrant power mesh with separate voltage and current
priority source modes.
As a measurement system, the Agilent N6705 displays the average
output voltage and current in Meter View. Waveforms are displayed
in Scope View, which you can adjust using vertical and horizontal
controls. The Data Logger View measures and charts average and
peak voltage and current measurements over an extended period.

8 Aux Voltage Measurement
connector
Auxiliary voltage measurement connector. Only available on Agilent N6705B
mainframes for use with Agilent N6781A power modules.
9 Wiring access ports Access for sense and output wire connections. Only available on Agilent N6705B
mainframes. Used for output connections on power modules rated > 20 A.
Also used for Agilent N678xA SMU power modules when extremely precise
measurements or output guarding is required.
WARNING SHOCK HAZARD The power cord provides a chassis ground through a third
conductor. Be certain that your power outlet is of the three-conductor type
with the correct pin connected to earth ground.
