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 of the customer’s failure to comply with the
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
operating instructions.
Environmental Conditions
Never use the instrument outside of the specified environmental conditions described in
the Environmental Characteristics of the specifications.
Ground the Instrument
This product is provided with protective earth terminals. To minimize shock hazard, the
instrument must be connected to the AC 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 injury
or death.
Before Applying Power
Verify that all safety precautions are taken. All connections must be made with the unit
turned off, and must be performed by qualified personnel who are aware of the hazards
involved. Improper actions can cause fatal injury as well as equipment damage. Note
the instrument's external markings described under "Safety Symbols".
Some power modules generate voltages exceeding 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.
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. Disconnect the power cable and any external circuits before
removing instrument covers.
Keysight N6700C Series User's Guide 10
Legal and Safety Information

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.
Fuses
The instrument contains an internal fuse, which is not customer accessible.
Cleaning
To prevent electric shock, always unplug the unit before cleaning. 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.
In Case of Damage
Instruments that are not functioning correctly, appear damaged or defective should be
made inoperative and secured against unintended operation until they can be repaired
by qualified service personnel.

Features at a Glance
The Keysight 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.
Keysight 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:
lN673xB, 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.
lN675xA High-Performance, Autoranging DC Power Modules provide low noise, high accuracy, fast
programming times, and advanced programming and measurement capabilities to speed test
throughput.
lN676xA 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.
lN678xA 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.
lN6783A Application-Specific DC Power Modules are two-quadrant low-wattage models spe-
cifically designed for battery charging/discharging and mobile communications applications.
lN679xA Electronic Load Modules are single-quadrant 100 W and 200 W models having constant
current, constant voltage, constant power, and constant resistance operating capabilities. They
also provide many of the existing measurement and protection features of the other power mod-
ules.

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.
Output features
lProgrammable voltage, current, power, or resistance - Full programming capability is provided for
the entire range of output voltage and current for all power modules. Power and resistance pro-
graming is available on Keysight N679xA load modules.
lLow output noise - Available on Keysight N676xA and N675xA power modules. Output noise is less
than 4.5 mV peak-to-peak, which is comparable to linear supplies.
lArbitrary waveform generation - This allows the output to act as a DC bias transient generator or
an arbitrary waveform generator.
lFast up/down programming - Available on Keysight N675xA, N676xA, and N678xA SMU power
modules. Response time is less than 1.5 millisecond from 10% to 90% of the output rating.
lFast transient response - Available on Keysight N675xA, N676xA, and N678xA SMU power mod-
ules. Transient response is less than 100 μs.
lOutput autoranging capability - Available on Keysight N676xA and N675xA power modules. Autor-
anging supplies the maximum rated power over a continuous range of voltage and current settings
lOutput On/Off sequencing - A turn-on/turn-off delay capability for each output allows output
on/off sequencing.
lRemote voltage sensing - Two remote sensing terminals are provided for each output. When
shipped, the remote sense jumpers are included in a separate bag. See Items Supplied.
lOutput protection - Each output has over-voltage, over-current, and over-temperature protection.
Over-voltage and over-current protection are programmable.
lMultiple-Quadrant operation - Available on Keysight N678xA SMU and N6783A power modules.
2- quadrant operation provides source and sink output capability. Keysight model N6784A offers
4- quadrant output operation.
lElectronic Load operation - Available on Keysight N679xA load modules. 100 W and 200 W input
ratings are available.
Measurement features
lMultiple-output/Single-output meter display - Switch between a 4-output summary view and a 1-
output detailed view of power system information. All power modules display real-time output
voltage and current measurements as well as status information.
lSeamless measurement autoranging - Available on Keysight N678xA SMU power modules. Out-
put measurements seamlessly autorange between ranges – however, the 10 μA current range
must be selected manually.
Keysight N6700C Series User's Guide 15
1 Quick Reference

lMicroampere current measurements - Available on Keysight N6761A, N6762A, and N678xA SMU
power modules. Current measurement can be made as low as 1 μA in the 10 μA range.
lFast Digitizing Available on Keysight N678xA SMU power modules. 5.12 μs/sample for one para-
meter; 10.24 μs/sample for two parameters.
System features
lChoice of three interfaces - GPIB (IEEE-488), LAN, and USB remote programming interfaces are
built in.
lBuilt-in Web server - A built-in Web server lets you control the instrument directly from an internet
browser on your computer.
lSCPI language - The instrument is compatible with the Standard Commands for Programmable
Instruments (SCPI).
lFront panel I/O setup - Menus let you set up GPIB and LAN parameters from the front panel.
lReal-time status information - The front panel indicates the status of each output. It also indicates
when a protection shut-down has occurred.
lModule identification - Each module has identifying data stored in non-volatile memory. Inform-
ation includes model number, serial number, and options.
lUniversal AC input - Mainframes have universal input voltage capability with active power factor
correction.
