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 modules, and the system lets you mix and match from over 30 different DC power and electronic load modules to create a 1- to 4-channel 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.

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. 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. 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, functional test, and optimizing the battery life of battery-powered devices.

The same modules also install in the Keysight N6705C DC Power Analyzer, a mainframe that 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. On the R&D bench it lets an engineer gain insight into a device's power consumption without writing code: set up and view critical turn-on and turn-off sequences, control bias-supply or load ramp-up and ramp-down rates, generate DC bias transients and disturbances as arbitrary waveforms, capture inrush current by triggering the integrated oscilloscope on the output's on/off key in single-shot mode, and log current and power consumption over seconds, minutes, hours, or days to capture anomalies. Because it is fully programmable and LXI Class C certified, it also serves ATE systems for test development, DUT troubleshooting, and visualizing results as tests execute.

ValueTronics stocks and holds its own test and measurement inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Holding inventory under our own roof lets us confirm configuration and condition directly and ship quickly to the engineers, labs, and production teams who rely on us.

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 each occupy two of the four slots.

Alongside the low-profile mainframes, the N6705C DC Power Analyzer mainframe has four module slots and 600 W of total available power and is ordered together with one to four modules as separate items, while the N6715C is the build-to-order version shipped fully assembled with one to four modules pre-installed. Module capability depends not only on the module's own hardware but also on the mainframe in which it is installed; modules placed in an N6705C gain front-panel scope view, arbitrary waveform generation, and data logging that are not present in the lower-profile N6700-series mainframes, 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 channel count, output rating, and interface needs 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 and not supported on the discontinued N6700A mainframe. The N6702A 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 (N6700B), 600 W (N6701A), or 1200 W (N6702A) of total available output power, and modules are rated at 50 W, 100 W, 300 W, or 500 W with output voltages ranging from 5 V up to 150 V depending on the module. Basic DC power modules cover programmable DC power with standard voltage and current measurement; high-performance autoranging modules span 50 W to 500 W up to 60 V and up to 50 A and add autoranging outputs that deliver maximum power across a range of voltage and current combinations; precision modules likewise reach 500 W and add low voltage and current ranges with precision measurement in the milliampere and microampere region and simultaneous voltage and current digitizing. Application-specific source/measure units provide up to 80 W with two- or four-quadrant operation for both sourcing and sinking power, and the N6790 electronic loads offer 100 W and 200 W modules with constant voltage, current, resistance, and power modes and programmable slew rates. The comparison table below details each model's output ratings and key performance specifications.

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 — consult the comparison table for which functions each model includes.

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

Product Core & Specifications

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

Important: This is a modular system — the DC power and electronic load modules (N6731B–N6792A) are not standalone instruments and require an N6700B/N6701A/N6702A or N6700C/N6701C/N6702C low-profile mainframe, or an N6705C DC Power Analyzer (sold separately), to operate; modules are ordered separately from the mainframe.

Important: Installing one of the 500 W modules in a 400 W mainframe (N6700B / N6700C) 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 for the low-profile mainframes; N6709C for the N6700C series); standard rack rails or slides are not compatible with the N6700 because of its 1U size and airflow requirements.

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

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: The N6705C mainframe has four module slots and holds one to four DC power or electronic load modules; modules are ordered separately and at least one module is required for the DC power analyzer to operate. 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: 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 N6702A/N6702C 1200 W mainframe, an AC mains rated 100–180 VAC cannot supply enough current for full rated power, and internal circuits limit module power to 600 W maximum at that input.

Important: When the N6702A 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: 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: Output current is derated 1% per °C above 40 °C ambient temperature.

Important: Series and parallel operation: the maximum series operation is 240 V, and the maximum rated parallel operation is 100 A per N6705 mainframe. Output terminal isolation: no output terminal may be more than ±240 VDC from any other terminal or chassis ground, and each module output is fully isolated and floating from ground and from one another.

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

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. The built-in digitizer runs to 200 kHz with up to 256 k samples/trace (512 k via SCPI) and roughly 30 kHz measurement bandwidth, logging to 4 gigabytes of internal non-volatile storage or USB.

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

Recommended pairing: control the family's DC power and electronic load modules in up to four N6705 mainframes — up to 16 installed modules — from a single PC with the BV9200B PathWave BenchVue Advanced Power Control and Analysis Software (the 14585A Control and Analysis Software provides the equivalent capability for these modules).

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.
