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, with electronic load modules available for power supply testing.

The N6744B is a 100 W DC power module from the N6740 100 W series, rated 35 V and 3 A. 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 and functional test.

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 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, and swapping or adding modules as test needs change.

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). 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.

The same modules run in two complementary mainframe styles. The low-profile N6700-series mainframes (1U, for ATE) are available in 400 W, 600 W, and 1200 W total-output-power tiers. The N6705C DC Power Analyzer is a four-slot, 600 W bench 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 — with all sourcing, loading, and measurement functions available directly from the front panel and no programming required. 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, to generate DC bias transients and disturbances as arbitrary waveforms, and to log current and power consumption over seconds, minutes, hours, or days to capture anomalies. A common task is inrush current measurement: triggering the integrated oscilloscope on the DC output's on/off key in single-shot mode captures the current flowing into the DUT as the output turns on. The N6715C is the build-to-order version of the analyzer, shipped fully assembled with one to four modules installed. Because the modules run in both bench and rack mainframes, results correlate between bench and manufacturing setups.

Each new 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 (not on the discontinued N6700A). 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 comparison table that follows summarizes each mainframe's power rating; module ratings and key performance specifications appear in the detailed table below it.

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 modules cover programmable DC power with standard voltage and current measurement; high-performance autoranging and precision modules add autoranging output capability that delivers maximum power across a range of voltage and current combinations, and the precision series adds low voltage and current ranges with precision measurement and simultaneous voltage and current digitizing. Source/measure units provide up to 80 W with two- or four-quadrant operation, 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 (HSTE), 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 — HSTE is optional on the basic, high-performance, and 300 W modules (option 054) and standard on the precision, SMU, application-specific, and load modules.

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

Product Core & Specifications

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.

Important: Output terminal isolation — no output terminal may be more than ±240 VDC from any other terminal or chassis ground. Maximum series operation is 240 V; maximum rated parallel operation is 100 A per N6705 mainframe.

Important: This is a modular system — the DC power and load modules (N6731B–N6792A) are not standalone instruments and require an N6700B/N6701A/N6702A, N6700C/N6701C/N6702C, or N6705C mainframe (or an N6710C/N6711C/N6712C build-to-order system), sold separately, 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 a 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 for the original 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: For models N6712A and 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 100–180 VAC cannot supply enough current to power the mainframe at full rated power; internal circuits limit 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 senses the available AC line power and 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: Output current is derated 1% per °C above 40 °C ambient temperature.

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

Important: In the DC power module specification table, values for the N6761A–N6766A precision modules and the N6781A/N6782A/N6784A/N6785A/N6786A SMU and N6783A application-specific modules are shown for the highest output/measurement range (these modules have multiple ranges); the N6783A-BAT and N6783A-MFG values are shown for the highest measurement range.

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. When sinking power, model N6784A can operate at 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: 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 captures to 200 kHz, up to 256 k samples/trace (512 k via SCPI), with roughly 30 kHz measurement bandwidth; the N6705C mainframe also provides 4 gigabytes of internal non-volatile storage and a built-in real-time clock.

Important: Each N6705C / N6715C mainframe has four 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.

Recommended pairing: add Keysight Control and Analysis Software — the 14585A software, or the BV9200B PathWave BenchVue Advanced Power Control and Analysis Software — to control the family's DC power and electronic load modules in up to four N6705 mainframes (as many as 16 installed modules) from a single PC.
