The Agilent N6753A is a high-performance autoranging DC power module in the Agilent N6700 Modular Power System (MPS) family, delivering 20 V, 50 A, and 300 W of programmable DC power. It is a double-wide module that occupies two of the four module slots in its mainframe, and because it is rated above 20 A, its high-current wiring is routed through the mainframe rear panel. As a module, it is not a standalone instrument: it installs into an Agilent N6700-series low-profile mainframe (N6700B / N6701A / N6702A) or an N6705 DC Power Analyzer (N6705A / N6705B), and its available capabilities depend not only on its own hardware but also on the hardware and firmware of the mainframe in which it is installed.

The N6700 Low-Profile MPS is 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 thirty different DC power and electronic load modules to build a 1- to 4-channel system tailored to specific test requirements — investing in high-performance outputs where speed and accuracy are needed, or basic-performance outputs for simple DC power. Power supplies and electronic loads are a fundamental component of test systems across aerospace and defense, consumer electronics, computers and peripherals, communications, semiconductor, and automotive electronics, where designers must reduce the rack space occupied by multiple supplies or loads while increasing test system throughput.

When the same modules are installed in the Agilent N6705 DC Power Analyzer, the system becomes a modular bench instrument that sources and measures DC voltage and current into a device under test, combining 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. Agilent positions it as an entirely new instrument category for R&D engineers, giving insight into a device's power consumption without writing a single line of code. 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 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 test and measurement 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 ship quickly to the engineers, labs, and production teams who rely on us.

Brand Heritage

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 centers on a mainframe with four module slots that accepts one to four DC power or electronic load modules. This modular design lets engineers mix and match over thirty different modules to build a solution optimized for specific test requirements — investing in high-performance outputs where speed and accuracy matter, and basic outputs where simple, economical DC power is sufficient. As test needs change, different modules can be purchased and swapped into the mainframe, so the system grows over time. 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.

The low-profile MPS family is built around three 1U mainframes — the 400 W N6700B, the 600 W N6701A, and the 1200 W N6702A — each holding one to four modules. The system can be purchased as a mainframe plus separately boxed modules that you assemble yourself, or as a build-to-order N6710B, N6711A, or N6712A configuration that ships as one mainframe with one to four modules installed. On the bench, the N6705 DC Power Analyzer mainframe is likewise ordered together with separately boxed modules, while the N6715B build-to-order configuration ships fully tested and assembled; the N6705B provides 600 W of total available power, and its rear panel provides access ports to route high-current wiring for modules rated above 20 A.

Modules are grouped into series: basic N6730/40/70 DC power modules, high-performance autoranging N6750 modules, precision N6760 modules, source/measure units (SMUs) in the N6780 series, application-specific N6783A modules, and N6790 DC electronic loads. Basic 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; 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 SMUs add multi-quadrant operation (two- and four-quadrant) and highly accurate measurements down to nanoamperes, with current ranges down to 10 microamperes, and are suited to optimizing power consumption and maximizing battery life of battery-powered devices; the application-specific N6783A-BAT and N6783A-MFG provide two-quadrant battery charge/discharge and mobile-device manufacturing test functions. The N6790 electronic loads offer 100 W and 200 W modules with constant voltage, current, resistance, and power modes and programmable slew rates.

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 and available options. 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. 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 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 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.

Product Core & Specifications

The detailed specifications below are for this N6753A module. A comparison table of key performance specifications for the other DC power modules in the family, and the mainframe characteristics, follow.

DC Power Module Key Performance Specifications (other models in the family)

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

DC Power Analyzer Mainframe Key Characteristics (N6705B / N6715B)

Important: A power module is not a standalone instrument; it requires an Agilent N6700-series mainframe (N6700B / N6701A / N6702A) or an N6705 DC Power Analyzer (N6705A / N6705B) to operate, and is ordered separately from the mainframe. At least one DC power module is required for the system to function, and the basic capabilities of a module depend on the hardware and firmware of the mainframe in which it is installed.

Important: Front-panel binding posts are rated for 20 A per post; modules with outputs rated greater than 20 A (such as the N6753A) route their high-current wiring through the N6705 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: Modules rated ≥ 300 W (N6753A–N6756A high-performance autoranging and N6763A–N6766A precision), as well as the N6792A electronic load, 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. If the sum of the installed module power exceeds 600 W, the mainframe's power management feature allocates available power to the outputs where it is needed.

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: Installing a 500 W module in the 400 W N6700B 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 (option 908 / N6709A); standard rack rails or slides are not compatible with the N6700 because of its 1U size and airflow requirements.

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, N6762A, and N6781A–N6784A.

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

Important: Option LGA (large-size FPGA) must be ordered on the N6751A and N6752A modules; it is required to support output sequencing between multiple mainframes.

Important: Output sequencing synchronization across multiple mainframes is supported on the N6700B, N6701A, and N6702A mainframes; it is not supported on the discontinued N6700A mainframe.

Important: For the N6702A mainframe (and N6712A build-to-order system), maximum output power is limited to 600 W at 100–120 VAC; to achieve full output power of 1200 W you must use option 929 and operate at 200–240 VAC. AC mains rated at 100–180 VAC cannot supply enough current to power the N6702A at full rated power, and internal circuits then limit module power to 600 W maximum.

Important: The 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 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: New modules N6753A and N6754A require mainframe firmware version C.02.00 or greater. If you add modules with model numbers N673xA, N673xB, N674xA, N674xB, N6753A, N6754A, or N677xA to an N672xA, you will not be able to access the Agilent 662x command set for any installed modules; only SCPI commands will be accepted.

Important: Published current/power ratings for Models N6751A and N6752A differ between the datasheet's specification table (page 16: N6751A 50 V/5 A/50 W, N6752A 50 V/10 A/100 W) and the ordering tables (pages 19 and 21: 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 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 Agilent / Keysight N6700 Modular Power System Family Specifications Guide, part number N6700-90001. Performance specifications for the N6780 Series 2-quadrant SMU modules (N6781A, N6782A) are in the separate N6780 Series Source/Measure Units data sheet, literature number 5990-5829EN.

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 modules simultaneously — from a single PC, adding enhanced data visualization and management.
