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. Keysight 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 a Keysight
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.

The Keysight 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 Keysight 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. Keysight N678xA
Source/Measure Units (SMU) have a multiple-quadrant power mesh with
separate voltage and current priority source modes.

As a measurement system, the Keysight 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.

When you receive your DC Power Analyzer, inspect it for obvious
damage that may have occurred during shipment. If there is damage,
notify the shipping carrier and nearest Keysight Sales and Support Office
immediately. Refer to www.keysight.com/find/assist

.

Until you have checked out the DC Power Analyzer, save the shipping
carton and packing materials in case the unit has to be returned. Check
the list under “Items Supplied” and verify that you have received these
items with your instrument. If anything is missing, please contact your
nearest Keysight Sales and Support Office.

Keysight N6705 User’s Guide

Installing the Unit

Safety Considerations

WARNING

Some models generate voltages in excess of 60 VDC. Ensure that
instrument connections, load wiring, and load connections are either
insulated or covered so that no accidental contact with lethal output
voltages can occur.

Environment

WARNING

Do not operate the unit in the presence of flammable gasses or fumes.

Cleaning

WARNING

SHOCK HAZARD To prevent electric shock, unplug the unit before
cleaning.

Power Module Location

This DC Power Analyzer is a Safety Class 1 instrument, which means it
has a protective earth terminal. That terminal must be connected to earth
ground through a power source equipped with a ground receptacle.

Refer to the Safety Summary page at the beginning of this guide for
general safety information. Before installation or operation, check the
DC Power Analyzer and review this guide for safety warnings and
instructions. Safety warnings for specific procedures are located at
appropriate places throughout this Guide.

The environmental conditions of the instrument are documented in
Appendix A. Basically, the instrument should only be operated indoors in
a controlled environment.

The dimensions of your instrument as well as an outline diagram are
given in Appendix A. Fans cool the DC Power Analyzer by drawing air
through the side and exhausting it out the opposite side and back. The
instrument must be installed in a location that allows sufficient space at
the sides and back of the unit for adequate air circulation.

Use a dry cloth or one slightly dampened with water to clean the
external case parts. Do not use detergent or chemical solvents. Do not
attempt to clean internally.

The location of the power modules inside the mainframe determines their
front panel output assignments. To view the module/output assignments,
turn the unit on, press the Settings key, then press Properties. The power
modules are listed under each output channel.

Outputs that are not connected to a power module will not be displayed
in the Meter view.

The information in this section applies if you have purchased an N6705
mainframe without the power modules installed, or if you are adding a
power module to the mainframe.

Turn the mainframe off and disconnect the power cord before installing
or removing power modules. Observe all standard electrostatic
discharge precautions before handling electronic components.

T10 Torx driver;

Small flat-blade screwdriver

5.5 mm hex wrench

Newer power modules can only be installed in N6705
mainframes with the latest firmware. Refer to the “Updates” section in
the front of this manual for more information. If your mainframe has the
latest firmware version, install the power module. If not, download and
install the latest version firmware from the web.

Loosen the thumb-screws to remove the covers. Turn the unit upside­down to remove the bottom cover.

Align the power module over the pins and gently push it down onto the
connector. Install the screws at each end of the power module. The
torque specification for the screws is 9 inch-pounds.

If you are installing a double-wide power module, you must first remove

the center deflector. Use a T10 Torx to remove the top deflector; use a

5.5 mm hex to remove the bottom deflector. Install the deflector in the
storage location on the opposite end of the module. Connect the
double-wide power module to output 1 or output 3 only.

Remove the 12A connector plug from the wire harness and install the 8­pin connector plug provided with the power module. Install the front
panel cable wires in the output connector as shown. Observe the output
color code. Tighten all connector screws. An adapter “A” is required to
install modules in Keysight N6705A mainframes.

For models N6781A and N6785A, also connect the auxiliary
measurement cable. Remove the cable from its rear panel storage
location and insert the connector into the power module. The cable’s
color code corresponds to the AUX voltage measurement label on the
rear panel.
