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 and functional test; the high-speed measurement capability supports design validation of battery-powered digital devices where understanding current drain and DUT power management is important. A companion configuration, the N6705 DC Power Analyzer, brings the same module platform to the R&D bench. It is a modular instrument that sources and measures DC voltage and current into a device under test, combining one to four DC power supplies (or electronic loads) with the functions of a digital multimeter, oscilloscope, arbitrary waveform generator, and data logger in a single integrated unit. All sourcing, loading, and measuring functions are available directly from the front panel with no programming required, giving R&D engineers insight into a device's power consumption without writing a single line of code. 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 supply or 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; the bench analyzer mounts in a standard 19-inch rack as a 4U instrument. 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, ready to support the engineers, labs, and production teams who rely on us. ## 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, which carries this product line forward today. 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 low-profile 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 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. For the bench, the same modules run in the N6705 DC Power Analyzer mainframe (four module slots, 600 W of total available power), allowing test correlation and program sharing between R&D and manufacturing. The N6705B is the four-slot DC Power Analyzer mainframe ordered together with separately boxed modules that you assemble yourself; buyers who prefer a fully tested, assembled system can instead order the N6715B build-to-order configuration, which ships as one mainframe with one to four installed modules. The current-generation N6705C and its build-to-order N6715C counterpart carry the same 600 W four-slot platform forward. The N6705 rear panel provides access ports to route high-current wiring for modules rated above 20 A. The modules themselves fall into distinct series — basic DC power (the N6730 50 W, N6740 100 W, and N6770 300 W ranges), high-performance autoranging (N6750 series), precision (N6760 series), source/measure units (N6780 series), application-specific modules (N6783A), and DC electronic loads (N6790 series) — so a single mainframe can combine a high-power autoranging output with several economical basic outputs. Basic modules provide clean, economical DC power at 50 W, 100 W, and 300 W with outputs up to 150 V and up to 20 A. High-performance autoranging and precision modules add autoranging outputs, lower noise, and faster voltage changes with available power up to 500 W; the precision series further provides dual programming and measurement ranges with 16-bit programming and 18-bit measurement precision and simultaneous voltage and current digitizing. The N6780 source/measure units add multi-quadrant (two- and four-quadrant) operation, battery emulator/charger and CC/CV load functions, ranges down to a 10 microampere current range, and highly accurate measurements down to nanoamperes (up to 80 W). The application-specific N6783A-BAT and N6783A-MFG provide two-quadrant battery charge/discharge and mobile-device manufacturing test functions at 18 W to 24 W. The N6790 electronic loads offer 100 W and 200 W modules with constant voltage, current, resistance, and power modes (up to 200 W, 60 V, and 40 A). Each pre-owned model linked below is its own dedicated product page with condition-matched pricing. Select the mainframe or module that matches your channel count, output rating, and interface needs, and review that page for its specific specifications and availability. The mainframes differ chiefly in total available output power — 400 W, 600 W, and 1200 W for the N6700B, N6701A, and N6702A respectively. Only the N6702A offers automatic AC-line power scaling: at turn-on it senses the available AC line power and limits output to 600 W so the 1200 W frame can be plugged into any standard outlet, reaching full 1200 W only when operated at 200–240 VAC (with option 929). Output sequencing synchronization across multiple mainframes 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, programming and measurement accuracy, and which series each belongs to. The 300 W and 500 W autoranging and precision modules (N6753A–N6756A and N6763A–N6766A) and the higher-power loads each occupy two of the four module slots; all other modules occupy one slot. The comparison table below lays out the mainframe ratings side by side.

Across the family, basic modules are rated 50 W, 100 W, and 300 W; high-performance autoranging and precision modules reach 500 W; source/measure units run 20 W to 80 W; the N6783A application-specific modules are 18 W to 24 W; and electronic loads provide 100 W to 200 W. The N6753A–N6756A and N6763A–N6766A double-wide modules and the N6792A load each occupy two of the four mainframe slots.

If the sum of the installed module power exceeds the mainframe's available output power, the power management feature allocates available power to the outputs where it is needed. > **Important:** Front-panel binding posts are rated for 20 A per post; modules with outputs rated greater than 20 A (such as the N6753A or N6792A) 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:** 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 mount hardware, rails, or slides will not work and are not compatible with the N6700 because of its 1U size and airflow requirements. > **Important:** DC power and electronic load modules require an N6700B/N6701A/N6702A (or N6710B/N6711A/N6712A build-to-order) mainframe or an N6705A/N6705B DC Power Analyzer mainframe to operate; a module is not a standalone instrument, and a module's available capabilities depend on the hardware and firmware of the mainframe in which it is installed. > **Important:** Option 760 (Output Disconnect/Polarity Reversal Relays) is not available on Models N6741B, N6751A, N6752A, N6761A, N6762A, and N6781A–N6784A, and it limits the output current to 10 A maximum on Models N6742B and N6773A. > **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 current is derated 1% per °C above 40 °C ambient temperature. > **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:** Maximum series operation is 240 V; maximum rated parallel operation is 100 A per N6705. > **Important:** Output sequencing synchronization across multiple mainframes is supported on the N6700B, N6701A, and N6702A mainframes; it is not supported on the discontinued N6700A mainframe. > **Important:** For model N6702A (and the N6712A system), maximum output power is limited to 600 W at 100–120 VAC; to achieve full 1200 W output you must use option 929 and operate at 200–240 VAC. AC mains circuits rated at 100–180 VAC cannot supply enough current to power the N6702A at full rated power; on such mains, internal circuits limit the power available to modules to 600 W maximum. > **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. > **Important:** New modules N6753A and N6754A require mainframe firmware version C.02.00 or greater (available at www.agilent.com/find/N6700firmware). > **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:** Published current/power ratings for Models N6751A and N6752A differ between the datasheet's specification table (N6751A 50 V/5 A/50 W, N6752A 50 V/10 A/100 W) and the ordering tables (both listed as 50 V/1.5 A/50 W); confirm the installed module's rating from the instrument before relying on maximum output. > **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 / Keysight N6700 Modular Power System Family Specifications Guide, part number N6700-90001. Performance specifications for the N6780 Series 2-quadrant SMU modules are in the separate 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 the family's DC power and electronic load modules installed in up to four N6705 mainframes — up to 16 modules — from a single PC, adding enhanced data visualization and management. The later BV9200B PathWave BenchVue Advanced Power Control and Analysis Software provides the same up-to-four-mainframe, up-to-16-module control from a single PC. ## About this Pre-Owned unit This pre-owned unit is inspected and functionally verified in-house before it ships and is backed by our pre-owned warranty.
