The Agilent N6756A is a high-performance autoranging DC power module from the N6700 Modular Power System family. The N6700 Low-Profile Modular Power System (MPS) is 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: a single mainframe holds one to four DC power modules, and the system lets you mix and match from over 30 different DC power modules to create a 1- to 4-channel DC power system tailored to specific test requirements. Engineers can invest in high-performance outputs where speed and accuracy are needed, or choose basic-performance outputs for simple DC power requirements.

The same modules also run in the Agilent N6705 DC Power Analyzer, a modular instrument that sources and measures DC voltage and current into a device under test. It combines 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, positioned as an entirely new instrument category for R&D engineers and giving insight into a device's power consumption without writing a single line of code, since all sourcing, loading, and measuring functions are available directly from the front panel.

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, maximizing battery life of battery-powered devices, and functional test.

The N6705 DC Power Analyzer is intended for R&D testing and design validation work at the bench. 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 device under test, 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 DC 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; it mounts in a standard 19-inch rack as a 4U instrument.

ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments we sell are on hand. Every used unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. This combination of held inventory and in-house verification of pre-owned equipment lets engineers buy a modular power system with confidence in both its availability and its condition, and lets us confirm configuration directly and ship quickly to the engineers, labs, and production teams who rely on us.

Brand Heritage

These instruments are branded Agilent Technologies. Agilent Technologies was established in 1999 as a spin-off of the test and measurement business of Hewlett-Packard. In 2014, that electronic measurement business was separated again into a newly formed company, Keysight Technologies, which carries this product line forward today. Equipment bearing the Agilent name reflects this period of the brand's corporate history.

Compare Other Models in This Series

The Agilent N6700 Modular Power System family pairs a choice of mainframe with an extensive catalog of interchangeable plug-in DC power and electronic load modules. The low-profile mainframes — the 400 W N6700B, the 600 W N6701A, and the 1200 W N6702A — each hold one to four modules within a single 1U chassis for automated test environments. The N6705 DC Power Analyzer extends the same module platform with front-panel scope view, arbitrary waveform generation, and data logging for the bench; its mainframe has four module slots and 600 W of total available power. The N6705B is ordered together with separately boxed modules that you assemble yourself, while the N6715B build-to-order configuration ships as one mainframe with one to four installed modules. The same modules are shared between the N6705 bench analyzer and the N6700 low-profile mainframes used in ATE, allowing test correlation and program sharing between R&D and manufacturing. Build-to-order low-profile systems are also available as the N6710B, N6711A, and N6712A.

The modules are organized into 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). As test needs change, different modules can be purchased and swapped into the mainframe, so the system grows over time. A power module's available capabilities depend not only on its own hardware but also on the hardware and firmware of the mainframe in which it is installed.

Each pre-owned model linked below is its own dedicated product page with condition-matched pricing. Select the mainframe or module configuration that fits your application, and review that page for its specific output ratings, options, and availability as a pre-owned unit.

The module series differ chiefly in performance level and output rating. Basic N6730/40/70 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 N6750 modules and precision N6760 modules add autoranging outputs, lower noise, and faster voltage changes, with available power up to 500 W up to 60 V and up to 50 A; the precision series further provides dual programming and measurement ranges with 16-bit programming and 18-bit measurement precision, low ranges, and simultaneous voltage and current digitizing. The N6780 source/measure units add multi-quadrant operation (two- or four-quadrant) and highly accurate measurements down to nanoamperes, rated up to 80 W. The N6790 electronic loads provide 100 W and 200 W modules with constant voltage, current, resistance, and power modes (up to 200 W, 60 V, and 40 A).

Across the mainframes, only the N6702A offers automatic AC-line power scaling: when plugged into a standard AC outlet it senses the available AC line power at turn-on and limits output to 600 W so a 1200 W frame can run from any standard outlet. 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 (it is not supported on the discontinued N6700A). Output ratings, ripple and noise, and voltage and current programming and measurement accuracy vary by module, and modules rated at 300 W or more in the high-performance and precision series occupy two of the four mainframe slots. 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 that follows summarizes these per-model differences so the correct module can be matched to the application.

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

DC Power Module Family Specifications

DC Power Analyzer Mainframe Key Characteristics (N6705B / N6715B)

Important Configuration & Application Notes

Important: Modules rated ≥ 300 W (N6753A–N6756A high-performance autoranging and N6763A–N6766A precision), along with the N6785A–N6786A and N6792A modules, each occupy two of the mainframe's four module slots; all other modules occupy one slot.

Important: The mainframe's total available output power is 600 W (low-profile mainframes are available in 400 W, 600 W, and 1200 W tiers). If the sum of the installed module power exceeds the mainframe's available power, the power management feature allocates available power to the outputs where it is needed.

Important: Power modules are not standalone instruments. They require an Agilent N6700-series mainframe (N6700B/N6701A/N6702A) or an N6705 DC Power Analyzer (N6705A/N6705B), and at least one DC power module is required for the system to function; modules are ordered separately from the mainframe. A module's capabilities depend on both its own hardware and the hardware and firmware of the mainframe in which it is installed.

Important: Installing one of the 500 W modules in a 400 W mainframe (such as the N6700B) may prevent that module from running at its full rated output power.

Important: Front-panel binding posts are rated for 20 A per post. For modules with outputs rated greater than 20 A (such as the N6753A or N6792A), high-current wiring must be routed through the N6705's 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: If you will be rack mounting the N6700, you must order the N6709A rack mount kit; standard rack rails or slides are not compatible with the N6700 because of its 1U size and airflow requirements.

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 mainframe.

Important: Option 760 (Output Disconnect/Polarity Reversal Relays) limits output current to 10 A maximum on Models N6742B and N6773A, and is not available on Models N6741B, N6751A, N6752A, N6761A, and N6762A.

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

Important: For model N6712A, 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. Likewise, an AC mains rated at 100–180 VAC cannot supply enough current to power the N6702A mainframe at its full rated power; when connected to a 100–180 VAC mains, internal circuits limit the power available to modules to 600 W maximum.

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: N6783A application-specific 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, after which a protect clear is required to resume operation).

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

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

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 power modules simultaneously — from a single PC, adding enhanced data visualization and management. (On later mainframes, the BV9200B PathWave BenchVue Advanced Power Control and Analysis Software provides equivalent control of up to four mainframes and as many as 16 installed modules.)
