The Keysight N6700 is a low-profile Modular Power System (MPS) — a 1U-high, multiple-output programmable DC power supply and electronic load system that lets test system integrators optimize performance, power, and price to match their test needs. Built on an advanced switching power supply design that fits within 1U of rack space, a single mainframe holds one to four DC power or electronic load modules, and the system lets you mix and match from over 30 different modules to create a 1- to 4-channel DC power system tailored to specific test requirements. Test system engineers can invest in high-performance outputs where speed and accuracy are needed, or choose basic performance outputs for simple DC power requirements, with electronic load modules available for power supply testing.

The N6700 MPS is designed for automatic test equipment (ATE) systems in R&D, design validation, and manufacturing, where designers must reduce the rack space occupied by multiple supplies or loads while increasing test system throughput. Power supplies and electronic loads of this kind are a fundamental component of test systems across aerospace and defense, consumer electronics, computers and peripherals, communications, semiconductor, and automotive electronics. 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 and maximizing battery life of battery-powered devices, and functional test.

The closely related Keysight N6705C is a DC power analyzer mainframe at the heart of the N6700 family. It combines one to four DC power supply or electronic load modules with the functions of a DMM, oscilloscope, arbitrary waveform generator, and data logger in a single integrated instrument that sources and measures DC voltage and current into a device under test, with all sourcing, loading, and measurement functions available directly from the front panel without requiring any programming. R&D engineers use it to gain insight into a device's power consumption without writing code, to set up and view critical turn-on and turn-off sequences, to control DC bias supply or electronic load ramp-up and ramp-down rates, and to generate DC bias transients and disturbances as arbitrary waveforms. 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. It can also log current and power consumption over seconds, minutes, hours, or days to capture anomalies, and being fully programmable and LXI Class C certified it also serves ATE systems for test development, DUT troubleshooting, and visualizing results as tests execute.

Brand Heritage

Keysight Technologies traces its measurement heritage to Hewlett-Packard, whose test and measurement business was spun off as Agilent Technologies in 1999. Agilent's electronic measurement division was then established as Keysight Technologies in 2014, the brand under which this product line is offered today.

Compare Other Models in This Series

The N6700 Modular Power System is a family built around a 1U mainframe and an extensive catalog of interchangeable DC power and electronic load modules. Rather than a fixed instrument, it gives test system designers the flexibility to mix and match from over 30 different modules to create a 1- to 4-channel DC power system optimized to meet specific test requirements — investing in high-performance outputs where speed and accuracy are needed, and basic outputs for simple DC power requirements.

The catalog organizes modules into distinct series: basic DC power modules (the N6730, N6740, and N6770 ranges), high-performance autoranging modules (N6750 series), precision modules (N6760 series), source/measure units (N6780 series), application-specific modules (N6783A), and DC electronic loads (N6790 series). Mainframes are available in 400 W, 600 W, and 1200 W tiers. Each module occupies one mainframe slot, except the double-wide N6753A–N6756A, N6763A–N6766A, N6785A–N6786A, and N6792A, which occupy two of the four slots.

The N6700 family centers on three low-profile mainframes — the N6700C/N6701C/N6702C (and the earlier N6700B/N6701A/N6702A) — rated at 400 W, 600 W, and 1200 W of total available output power, each holding one to four modules within a single 1U chassis. The N6705C DC Power Analyzer mainframe is the bench counterpart: it has four slots and 600 W of total available power, accepts one to four modules ordered separately, and adds front-panel scope view, arbitrary waveform generation, and data logging that the lower-profile N6700C-series mainframes do not provide. The N6715C is the build-to-order version shipped fully assembled with one to four modules installed; the same modules also run in the N6700-series low-profile mainframes used for ATE, allowing test correlation between bench and manufacturing setups.

Each model linked below is its own dedicated product page with condition-matched pricing. Select the specific mainframe or module that fits your configuration to see its availability and price.

Across the mainframes, output sequencing can be synchronized between multiple units by wiring the rear-panel I/O ports together — a capability supported on the N6700B, N6701A, and N6702A mainframes but not on the discontinued N6700A. The N6702A/N6702C 1200 W mainframe additionally senses the available AC line power at turn-on and automatically scales back output power to avoid overloading a standard AC outlet, limiting output to 600 W so a high-power mainframe can be plugged into any standard outlet.

The models differ primarily in mainframe power and in module output ratings and performance class. Mainframes provide 400 W, 600 W, or 1200 W of total available output power, and modules are rated from 18 W up to 500 W with output voltages ranging from 0–5 V up to 0–150 V depending on the module. Basic DC power modules cover 50 W, 100 W, and 300 W outputs up to 150 V and up to 20 A; high-performance autoranging and precision modules span 50 W to 500 W up to 60 V and up to 50 A, adding autoranging outputs that deliver maximum power across a range of voltage and current combinations; application-specific source/measure units provide 20 W to 80 W with two- or four-quadrant operation; the application-specific N6783A modules target battery and mobile-communications testing at 18 W to 24 W; and the N6790 electronic loads offer 100 W and 200 W modules (up to 60 V and 40 A) with constant voltage, current, resistance, and power modes. High-Speed Test Extensions, output disconnect relays (option 761), and output disconnect/polarity reversal relays (option 760) are available according to each module's row in the options table. The comparison table below details each model's output ratings and key performance specifications.

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

Product Core & Specifications

N6735B DC Output Ratings & Performance

DC Power Module Key Performance Specifications (Family)

Values for the N6761A–N6766A precision modules and the N6781A/N6782A/N6784A/N6785A/N6786A SMU modules are shown for the highest range, as these modules have multiple output and measurement ranges; N6783A-BAT and N6783A-MFG values are shown for the highest measurement range.

Important: This is a modular system: the DC power and electronic load modules (N6731B–N6792A) are not standalone instruments and require an N6700C, N6701C, N6702C, or N6705C mainframe (or N6710C/N6711C/N6712C build-to-order system), sold separately, to operate; at least one module is required for the DC power analyzer to operate.

Important: Each module occupies one module slot, except for the N6753A–N6756A, N6763A–N6766A, N6785A–N6786A and N6792A, which each occupy two of the four mainframe module slots.

Important: Installing one of the 500 W modules in the 400 W N6700B/N6700C mainframe may prevent that module from running at its full rated output power.

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: If you will be rack mounting the N6700, you MUST order the rack mount kit (N6709A / N6709C); standard rack rails or slides are not compatible with the N6700 because of its 1U size and airflow requirements.

Important: Front-panel binding posts are rated for 20 A per post; modules rated above 20 A, such as the N6753A or N6792A, require high-current wiring routed through the rear panel.

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. The maximum series operation is 240 V, and the maximum rated parallel operation is 100 A per N6705 mainframe.

Important: For model N6712A / N6712C, 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. For the N6702C mainframe, an AC mains rated at 100–180 VAC cannot supply enough current to power the mainframe at its full rated power; internal circuits limit the module power to 600 W maximum at that input.

Important: When the N6702A/N6702C 1200 W mainframe is plugged into a standard AC outlet, it automatically limits output power to 600 W to prevent overloading the AC line.

Important: Each N6705C / N6715C mainframe has 4 module slots and provides 600 W total available output power. If the sum of the installed modules' power exceeds the mainframe's available output power, use Keysight's power management capability to allocate mainframe power to the outputs where it is needed.

Important: Output current is limited on some modules when option 760 (Output Disconnect/Polarity Reversal Relays) is installed; option 760 limits output current to 10 A maximum on models N6742B and N6773A, and is not available on models N6741B, N6751A, N6752A, N6761A, N6762A, and N6781A–N6786A.

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

Important: Multi-mainframe output sequencing synchronization is supported on the N6700B, N6701A, and N6702A mainframes; it is not supported on the discontinued N6700A mainframe.

Important: Arbitrary waveform generation, scope view, and the related N6705 oscilloscope measurement capabilities apply only when the power modules are installed in a Keysight N6705 DC Power Analyzer.

Important: The Keysight N6791A and N6792A Electronic Load Modules are not supported on the previous Keysight mainframes N6700B, N6701A, N6702A, N6705A, and N6705B.

Important: Keysight 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 time; when the internal temperature exceeds its safe limit, the output latches off and a protect clear is required to resume operation.

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 Keysight N6700 Modular Power System Family Specifications Guide, part number N6700-90001.

Recommended pairing: add the BV9200B PathWave BenchVue Advanced Power Control and Analysis Software (or the 14585A Control and Analysis Software) to control the family's DC power and electronic load modules in up to four mainframes — as many as 16 installed modules — from a single PC.
