The Keysight N6700 is a low-profile Modular Power System (MPS) — a 1U-high, multiple-output programmable DC power supply 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 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 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.

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 same modules also run in the N6705C DC Power Analyzer, which brings them to the R&D bench by combining one to four DC power supplies or electronic loads 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. Engineers use it to gain insight into a device's power consumption, set up and view turn-on/turn-off sequences, control ramp-up and ramp-down rates, generate 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.

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). 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. 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 DC Power Analyzer gain front-panel scope view, arbitrary waveform generation, and data logging that are not present in the lower-profile N6700-series mainframes.

Mainframes are available in 400 W, 600 W, and 1200 W tiers. The original-generation mainframes (N6700B, N6701A, N6702A) and the current-generation mainframes (N6700C, N6701C, N6702C) provide 400 W, 600 W, and 1200 W of total available output power respectively; the N6705C is the four-slot DC power analyzer mainframe ordered together with modules as separate items, providing 600 W of total available power, while the N6715C is the build-to-order version shipped fully assembled with one to four modules installed. The N6705C also offers front-panel binding posts rated 20 A per post, 4 gigabytes of internal non-volatile storage, a built-in real-time clock, and power management that allocates mainframe power to the outputs that need it.

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. 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. Basic DC power modules cover programmable DC power at 50 W, 100 W, and 300 W up to 150 V and up to 20 A 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 precise control and 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; the N6783A application-specific 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. Output power ratings across the series therefore span 18 W to 500 W per module, with DC output voltages spanning 0–5 V up to 0–150 V. 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; High-Speed Test Extensions are optional on the basic, high-performance, and 300 W modules and standard on the precision, SMU, application-specific, and load modules. 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

The N6774A is a high-performance autoranging DC power module in the N6700 family. The table below places it alongside the other DC power modules in the series so its ripple & noise, programming accuracy, and measurement accuracy can be compared at a glance. Performance specification values for the N6761A–N6766A precision modules are shown 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 mainframe, or an N6705C DC Power Analyzer, to operate; modules are ordered separately and at least one module is required for the system to operate. (Build-to-order systems N6710C/N6711C/N6712C and N6715C ship fully assembled with modules pre-installed.)

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: The N6753A–N6756A, N6763A–N6766A, N6785A–N6786A, and N6792A modules each occupy two of the four mainframe module slots; all other modules occupy one module slot.

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 original-generation mainframes, N6709C for the current generation); standard rack rails or slides are not compatible with the N6700 because of its 1U size and airflow requirements.

Important: For models 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 senses the available AC line power at turn-on and automatically limits output power to 600 W to prevent overloading the AC line.

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: 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: Front-panel binding posts are rated for 20 A per post; for modules with outputs rated above 20 A, such as the N6753A or N6792A, high-current wiring must be routed through the N6705's rear panel.

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

Important: Option 760 (Output Disconnect/Polarity Reversal Relays) limits the 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: 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 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. Arbitrary waveform generation, scope view, and the related oscilloscope measurement capabilities apply only when the power modules are installed in a Keysight N6705 DC Power Analyzer.

Important: The N6705C DC Power Analyzer includes a built-in digitizer to 200 kHz, up to 256 k samples/trace (512 k via SCPI), and approximately 30 kHz measurement bandwidth.

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