The Agilent N6700 Low-Profile Modular Power System (MPS) is a 1U-high, multiple-output programmable DC power supply system that gives test system integrators the flexibility to mix and match from over 30 different DC power modules. The result is a 1- to 4-channel DC power system that can be optimized to match a specific set of test requirements, letting engineers invest in high-performance outputs where speed and accuracy matter and basic outputs where simple DC power is all that is needed. The system is built on an advanced switching power supply design that fits within 1U of rack space.

The N6700 MPS is built for automatic test equipment (ATE) systems in R&D, design validation, and manufacturing. Power supplies are a fundamental component of test systems across aerospace and defense, consumer electronics, computers and peripherals, communications, semiconductor, and automotive electronics — industries where complex ATE systems often require multiple power sources and where reducing occupied rack space and increasing test throughput are constant pressures. Within the family, precision modules are suited to semiconductor and passive device testing where a precisely controlled output and highly accurate measurements are needed, while the source/measure unit modules support applications such as battery drain analysis, optimizing power consumption, maximizing battery life, and functional test.

ValueTronics stocks and holds its own test-and-measurement inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Keeping inventory on hand and verifying used units in our own facility means an order can be filled quickly and with confidence in the unit's condition.

Brand Heritage

These instruments are branded Agilent Technologies. Agilent Technologies was formed in 1999 as a spin-off of Hewlett-Packard's test and measurement business; that electronic measurement business was subsequently established as Keysight Technologies in 2014. Equipment originally branded Agilent is part of that continuous corporate lineage.

Compare Other Models in This Series

The N6700 Modular Power System is a single 1U platform built around three mainframes — the 400 W N6700B, the 600 W N6701A, and the 1200 W N6702A — each able to hold one to four DC power modules. Rather than a fixed-configuration supply, it is a user-reconfigurable system: integrators select from over 30 modules to assemble exactly the channel count, voltage, current, and performance grade a test station calls for. The same module platform is also offered as the N6705 DC Power Analyzer, a bench mainframe described below.

The modules themselves fall into distinct series — basic DC power (the N6730/40/70 ranges), high-performance autoranging (N6750), precision (N6760), source/measure units (N6780), and application-specific (N6783A) — plus the N6790 electronic loads, so a single mainframe can combine a high-power autoranging output with several economical basic outputs. The system can be purchased as a mainframe plus separate modules for self-assembly, or as a build-to-order N6710B, N6711A, or N6712A system shipped fully assembled.

Each pre-owned model below is its own dedicated product page with condition-matched pricing. Select the mainframe or module that matches your configuration to see its pre-owned availability and details.

The mainframes differ chiefly in total available output power — 400 W, 600 W, and 1200 W for the N6700B, N6701A, and N6702A respectively. The 1200 W N6702A automatically senses the available AC line power at turn-on and limits output to 600 W on a standard outlet, drawing full 1200 W power only when operated at the higher AC input (200 VAC with option 929). Cross-mainframe output sequencing synchronization — wiring the rear-panel I/O ports together — is supported on the N6700B, N6701A, and N6702A and is not supported on the discontinued N6700A mainframe.

Among the modules, the differences are output rating (from 18 W up to 500 W), voltage and current range, ripple and noise, and programming and measurement accuracy, along with which series each belongs to. The 300 W and 500 W autoranging and precision modules each occupy two of the four module slots. The comparison table below lays out the headline ratings side by side so the right module can be matched to each output requirement.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

N6705 DC Power Analyzer Configuration

The same N6700 modules also run in the Agilent N6705 DC Power Analyzer, a modular bench instrument that sources and measures DC voltage and current into a device under test. The N6705 combines one to four DC power supply or electronic load modules with the functions of a digital multimeter, oscilloscope, arbitrary waveform generator, and data logger in a single integrated unit, positioned as an entirely new instrument category for R&D engineers — all sourcing, loading, and measurement functions are available directly from the front panel without writing a single line of code. Because the same modules are shared between the N6705 bench analyzer and the N6700 low-profile mainframes used in ATE, test correlation and program sharing between R&D and manufacturing are possible.

The analyzer is intended for R&D testing and design validation at the bench. Engineers use it to set up and view turn-on and turn-off sequences, measure and display voltage and current versus time to visualize power into the DUT, control DC bias and electronic-load ramp-up and ramp-down rates, generate DC bias transients and disturbances, and log data over seconds, minutes, hours, or even days to capture current and power consumption or anomalies. A common task is inrush current measurement: triggering the integrated oscilloscope on the output's on/off key in single-shot mode captures the current flowing into the DUT as the output turns on. While designed primarily as an R&D bench tool, it is fully programmable and LXI Class C certified, which makes it useful in ATE systems for visualizing results as tests execute, for device troubleshooting, and for test development; it mounts in a standard 19-inch rack as a 4U instrument.

The N6705B is the four-slot DC Power Analyzer mainframe, ordered together with separately boxed modules that you assemble yourself, and it provides 600 W of total available power; the N6715B (and later N6715C) build-to-order configuration ships as one mainframe with one to four installed modules. The N6705 provides four module slots, front-panel binding posts rated 20 A per post, 4 gigabytes of internal non-volatile storage, a built-in real-time clock, and power management that allocates available mainframe power to the outputs where it is needed. The N6705B rear panel also provides access ports to route high-current wiring for modules rated above 20 A. Modules installed in an N6705 DC Power Analyzer gain front-panel scope view, arbitrary waveform generation, and data logging that are not present in the lower-profile N6700-series mainframes.

Product Core & Specifications

Full DC output ratings, ripple and noise, and programming and measurement accuracy for every companion module in the family — the N6730/N6740/N6770 basic, N6750 high-performance autoranging, N6760 precision, N6780 source/measure, and N6783A application-specific modules — are published on each module's own dedicated product page; the headline voltage, current, and power ratings are summarized in the comparison table above.

Replaces: per the manufacturer, this model replaces 6621A, 6622A, 6623A, 6624A, 6625A, 6626A, 6627A, 6628A, 6629A.

Important: DC power and electronic load modules require an N6700B/N6701A/N6702A or N6705 DC Power Analyzer (N6705A/N6705B) mainframe to operate; a module is not a standalone instrument and is ordered separately. The basic capabilities of a power module depend not only on its own hardware but also on the hardware and firmware of the mainframe in which it is installed.

Important: Each module occupies one module slot, except the N6753A–N6756A and N6763A–N6766A double-wide modules, which each occupy two of the four mainframe slots; modules rated ≥ 300 W in the high-performance and precision series are double-wide.

Important: The mainframe's total available output power is fixed (e.g. 600 W on the N6705B). If the sum of the installed module power exceeds the available output power, the mainframe's power management feature allocates available power to the outputs where it is needed.

Important: Installing a 500 W module in the 400 W N6700B mainframe may prevent that module from running at its full rated output power.

Important: Output current is derated 1% per °C above 40 °C ambient temperature.

Important: Front-panel binding posts are rated for 20 A per post; for modules with outputs rated greater than 20 A (such as the N6753A), high-current wiring must be routed through the N6705's rear panel — the N6705B mainframe provides rear-panel access ports for this (for an N6705A mainframe, order N6705U-057 to replace the rear panel).

Important: Option 760 (Output Disconnect/Polarity Reversal Relays) limits the output current to 10 A maximum on Models N6742B and N6773A, and is not available on Models N6741B, N6751A, N6752A, N6761A, and N6762A.

Important: Option 2UA (200 µA measurement range) is available only on Models N6761A and N6762A.

Important: Option LGA (large-size FPGA) must be ordered on the N6751A and N6752A modules; it is required to support output sequencing between multiple mainframes.

Important: Output sequencing synchronization across multiple mainframes is supported on N6700B, N6701A and N6702A mainframes; it is not supported on the discontinued N6700A mainframe.

Important: For model N6712A, the maximum output power is limited to 600 W at 100 VAC; to achieve full output power of 1200 W you must use option 929 and operate at 200 VAC. AC mains circuits rated at 100–180 VAC cannot supply enough current to power the N6702A mainframe at full rated power; on a 100–180 VAC mains, internal circuits limit the power available to modules to 600 W maximum.

Important: If you will be rack mounting your N6700, you must order the rack mount kit (option 908 / N6709A). Standard rack mount hardware, rails, or slides are not compatible with the N6700 because of its 1U size and airflow requirements.

Important: When configuring a mainframe with fewer than four filled module slots, you must order a filler panel kit (N6708A); each kit contains three filler panels, and every empty module slot must be filled with a filler panel for proper operation.

Important: Maximum series operation is 240 V; maximum rated parallel operation is 100 A per N6705. Output terminal isolation: no output terminal may be more than ±240 VDC from any other terminal or chassis ground. When using the auxiliary measurement input terminals on the N6781A, no output or input terminal may be more than ±60 VDC from any other terminal and chassis ground.

Important: N6783A modules cannot be used in series with other N6783A modules or any other N67xx module. When sinking power, Model N6784A can operate at the maximum rated output power for only a limited amount of time; the unit monitors internal power device temperature and latches the output off if the safe limit is exceeded (annunciated by the OT status bit).

Important: New modules N6753A and N6754A require mainframe firmware version C.02.00 or greater (available at www.agilent.com/find/N6700firmware). If you add modules with model numbers N673xA, N673xB, N674xA, N674xB, N6753A, N6754A or N677xA to an N672xA, you will not be able to access the Agilent 662x command set for any installed modules; only SCPI commands will be accepted.

Important: This data sheet does not include a comprehensive list of all power module specifications and characteristics; complete performance specifications and supplemental characteristics for all power modules are in the Agilent N6700 Modular Power System Family Specifications Guide, part number N6700-90001. Performance specifications for the N6780 Series 2-quadrant SMU modules (N6781A, N6782A) are in the N6780 Series Source/Measure Units (SMUs) for the N6700 Modular Power System Data Sheet, literature number 5990-5829EN.

Recommended pairing: the Agilent 14585A Control and Analysis Software controls up to four N6705 mainframes — up to 16 power and electronic load modules simultaneously — from a single PC, adding enhanced data visualization and management.
