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 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. The precision modules in the family are suited to semiconductor and passive device testing where a precisely controlled output and highly accurate measurements are needed, while the high-speed measurement capability supports design validation of battery-powered digital devices where understanding current drain and DUT power management is important. The source/measure unit modules support applications such as battery drain analysis 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.
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, which carries this product line forward today. Equipment originally branded Agilent is part of that continuous corporate lineage.
The N6700 Modular Power System is a single platform built around a 1U mainframe and an extensive catalog of interchangeable DC power and electronic load 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, then swap or add modules as test needs change.
The low-profile mainframes come in three power tiers — the 400 W N6700B, the 600 W N6701A, and the 1200 W N6702A — each holding one to four modules. The same module platform is also offered as the N6705 DC Power Analyzer, a bench mainframe that adds front-panel scope view, arbitrary waveform generation, and data logging for R&D work; the N6705 and the low-profile N6700 mainframes share the same modules, allowing test correlation and program sharing between R&D and manufacturing. 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.
The modules fall into distinct series — basic DC power (the N6730, N6740, and N6770 ranges), high-performance autoranging (N6750 series), precision (N6760 series), source/measure units (N6780 series), application-specific modules (N6783A), and electronic loads (N6790 series) — so a single mainframe can combine a high-power autoranging output with several economical basic outputs. Autoranging output is available on the high-performance and precision modules; the precision series adds dual programming and measurement ranges with 16-bit programming and 18-bit measurement precision and simultaneous voltage and current digitizing; the source/measure units add multi-quadrant operation and highly accurate measurements down to nanoamperes; and the electronic load modules offer constant voltage, current, resistance, and power priority modes with programmable slew rates.
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 — and only the N6702A offers automatic AC-line power scaling: it senses the available AC line power at turn-on and limits output to 600 W on a standard outlet, requiring 200 VAC operation (and option 929) to reach its full 1200 W, so a high-power mainframe can be plugged into any standard outlet. Cross-mainframe output sequencing is supported on the N6700B, N6701A, and N6702A by wiring the rear-panel I/O ports together.
Among the modules, the differences are output rating (from 18 W up to 500 W), voltage and current range (5 V up to 150 V), 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 these per-model ratings side by side so the right module can be matched to each output requirement.

| Net weight (N6705 with 4 modules, typical) | 16 kg / 35 lbs |
| Dimensions (Height / Width / Depth) | 194.7 mm / 425.6 mm / 313 mm (7.665 in. / 16.756 in. / 12.319 in.) |
| Module slots | 4 |
| N6705 internal storage / clock | 4 gigabytes of internal non-volatile storage and a built-in real-time clock; built-in digitizer to 200 kHz, up to 256 k samples/trace (512 k via SCPI), ~30 kHz measurement bandwidth |
Important: 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: Front-panel binding posts are rated for 20 A per post; modules with outputs rated greater than 20 A (such as the N6753A) route their high-current wiring through the N6705 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: Power modules require an Agilent N6700-series (N6700B/N6701A/N6702A) or N6705 DC Power Analyzer (N6705A/N6705B) mainframe to operate; a module is not a standalone instrument. 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. At least one DC power module is required for the system to function.
Important: The mainframe's total available output power is 600 W (N6705B / N6715B). 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 N6700B 400 W mainframe may prevent that module from running at its full rated output power.
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. The N6753A and N6754A 300 W high-performance autoranging modules each occupy two slots; all other modules occupy one slot.
Important: Option 760 (Output Disconnect/Polarity Reversal Relays) is not available on Models N6741B, N6751A, N6752A, N6761A, N6762A, and N6781A–N6784A, and limits the output current to 10 A maximum on Models N6742B and N6773A.
Important: Option 2UA (200 µA measurement range) is only available 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: For model N6712A (and N6702A), 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 rated at 100–180 VAC cannot supply enough current to power the N6702A mainframe at its full rated power; on a 100–180 VAC mains, internal circuits limit module power to 600 W maximum.
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: Rack mounting requires the rack mount kit (option 908 / N6709A); standard rack rails or slides are not compatible with the N6700 because of its 1U size and airflow requirements.
Important: Maximum series operation is 240 V; maximum rated parallel operation is 100 A per N6705 mainframe.
Important: Output current is derated 1% per °C above 40 °C ambient temperature.
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: N6783A modules cannot be used in series with other N6783A modules or any other N67xx module.
Important: 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: 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. New modules N6753A and N6754A require mainframe firmware version C.02.00 or greater.
Important: Performance specifications for the N6780 Series source/measure unit modules are not included in this overview; see the N6780 Series Source/Measure Units (SMUs) for the N6700 Modular Power System Data Sheet, literature number 5990-5829EN. Complete performance specifications and supplemental characteristics for all power modules are in the N6700 Modular Power System Family Specifications Guide, part number N6700-90001.
Recommended pairing: the Agilent 14585A Control and Analysis Software controls the family's DC power and electronic load modules in up to four N6705 mainframes — up to 16 modules simultaneously — from a single PC, adding enhanced data visualization and management.
