The Agilent N6734B is a 35 V, 1.5 A, 50 W basic DC power module from the N6700 Series of 50 W DC power modules. It installs in the Agilent N6700 Low-Profile Modular Power System (MPS) — a 1U-high, multiple-output programmable DC power supply system that gives test system integrators the flexibility to mix and match from over 30 different DC power modules. The result is a 1- to 4-channel DC power system that can be optimized to match a specific set of test requirements, letting engineers invest in high-performance outputs where speed and accuracy matter and basic outputs where simple, economical DC power is all that is needed.

The N6700 MPS is built for automatic test equipment (ATE) systems in R&D, design validation, and manufacturing. Power supplies are a fundamental component of test systems across aerospace and defense, consumer electronics, computers and peripherals, communications, semiconductor, and automotive electronics — industries where complex ATE systems often require multiple power sources and where reducing occupied rack space and increasing test throughput are constant pressures. 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; their high-speed measurement capability supports design validation of battery-powered digital devices where understanding current drain and DUT power management is important.

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, with all sourcing, loading, and measurement functions available directly from the front panel 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 DUT, control DC bias and 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, so it also serves ATE systems for visualizing results as tests execute, for DUT 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 and ready to ship. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Keeping inventory on hand and verifying used units in our own facility means an order can be filled quickly and with confidence in the unit's condition.

Brand Heritage

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

Compare Other Models in This Series

The N6700 Modular Power System is a single platform built around a 1U mainframe and an extensive catalog of interchangeable DC power and electronic load modules. Rather than a fixed-configuration supply, it is a user-reconfigurable system: integrators select from over 30 modules to assemble exactly the channel count, voltage, current, and performance grade a test station calls for, and can swap or add modules as test needs change. The low-profile mainframes — the 400 W N6700B, the 600 W N6701A, and the 1200 W N6702A — target automated test environments, while the N6705 DC Power Analyzer brings the same module platform to the R&D bench. 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; modules installed in an N6705 DC Power Analyzer gain front-panel scope view, arbitrary waveform generation, and data logging.

The modules fall into distinct series: basic DC power modules (the N6730 50 W, N6740 100 W, and N6770 300 W ranges), high-performance autoranging modules (N6750 series), precision modules (N6760 series), source/measure units (N6780 series), application-specific modules (N6783A), and electronic loads (N6790 series). So a single mainframe can combine a high-power autoranging output with several economical basic outputs. The system can be purchased as a mainframe plus separate modules for self-assembly, or as a build-to-order N6710B, N6711A, or N6712A system shipped fully assembled; the N6705B is the four-slot DC Power Analyzer ordered with separate modules, and the N6715B is its build-to-order, fully-assembled equivalent.

Each pre-owned model below is its own dedicated product page with condition-matched pricing. Select the mainframe or module that matches your channel count, output rating, and interface needs, and review that page for its specific specifications and availability.

The mainframes differ chiefly in total available output power — 400 W, 600 W, and 1200 W for the N6700B, N6701A, and N6702A respectively — and only the N6702A offers the automatic AC-line power scaling that lets a 1200 W frame run from a standard outlet: it senses the available AC line at turn-on and limits output to 600 W on a standard outlet, requiring 200 VAC operation (and option 929) to reach its full 1200 W. Cross-mainframe output sequencing synchronization is supported on the N6700B, N6701A, and N6702A by wiring the rear-panel I/O ports together.

Among the modules, the differences are output rating (from 18 W up to 500 W), voltage range (0–5 V up to 0–150 V), ripple and noise, and programming and measurement accuracy, along with which series each belongs to. 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; the precision series further provides dual programming and measurement ranges with 16-bit programming and 18-bit measurement precision and simultaneous voltage and current digitizing for milliampere and microampere work. The N6780 source/measure units add two- and four-quadrant operation, battery emulator/charger and CC/CV load functions, ranges down to a 10 microampere current range, and highly accurate measurements down to nanoamperes, at 20 W to 80 W. The application-specific N6783A modules (18 W to 24 W) target battery charge/discharge for mobile-device designers and DC power for testing battery-powered mobile devices in manufacturing or automated test. The N6790 electronic loads offer 100 W and 200 W modules with constant voltage, current, resistance, and power priority modes and programmable slew rates. The 300 W and 500 W autoranging and precision modules (N6753A–N6756A and N6763A–N6766A) and the higher-power loads each occupy two of the four module slots. The comparison table below lays out these per-model ratings side by side so the right module can be matched to each output requirement.

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

Mainframe Characteristics (N6705 DC Power Analyzer)

Replaces: per the manufacturer, this model replaces 6621A, 6622A, 6623A, 6624A, 6625A, 6626A, 6627A, 6628A, 6629A.

Important: DC power and electronic load modules are not standalone instruments; they require an N6700-series (N6700B/N6701A/N6702A) low-profile mainframe, an N6705 DC Power Analyzer (N6705A/N6705B), or an N6710C/N6711C/N6712C build-to-order system, and are ordered separately from the mainframe. The basic capabilities of a power module depend not only on its own hardware but also on the hardware and firmware of the mainframe in which it is installed.

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. Identically rated outputs can be operated directly in parallel or series; auto-series and auto-parallel are not available.

Important: Each module occupies one module slot, except the double-wide N6753A–N6756A and N6763A–N6766A modules and the N6792A load, which each occupy two of the four mainframe slots. The N6753A and N6754A 300 W high-performance autoranging modules are among the double-wide modules.

Important: The mainframe's total available output power is 600 W (N6705B / N6715B). If the sum of the installed module power exceeds the mainframe's available output power, the power management feature allocates available power to the outputs where it is needed.

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 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: A 500 W module installed in the 400 W N6700B mainframe cannot be operated at its full rated output power.

Important: For proper operation, you must fill any empty module slots with filler panels. 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.

Important: If you will be rack mounting your N6700, you must order the rack mount kit (option 908 / N6709A). Standard rack mount hardware will not work; 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: Option 760 (Output Disconnect/Polarity Reversal Relays) is not available on Models N6741B, N6751A, N6752A, N6761A, N6762A, and N6781A–N6784A; when installed, it limits the output current to 10 A maximum on Models N6742B and N6773A.

Important: Option 2UA (200 µA measurement range) is only available 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 model N6712A (and the N6702A 1200 W mainframe), the 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. An AC mains rated 100–180 VAC cannot supply enough current to power the N6702A mainframe at its full rated power, so internal circuits limit the power available to modules to 600 W maximum at that input. When first turned on, the N6702A 1200 W mainframe senses the available AC line power and limits output to 600 W so the high-power mainframe can be plugged into any standard outlet.

Important: 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), requiring a protect clear to resume operation.

Important: 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: New modules N6753A and N6754A require mainframe firmware version C.02.00 or greater (available at www.agilent.com/find/N6700firmware).

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: Performance specifications for the N6780 Series 2-quadrant SMU modules (N6781A, N6782A) are not included in this datasheet; see the N6780 Series Source/Measure Units (SMUs) for the N6700 Modular Power System Data Sheet, literature number 5990-5829EN. This data sheet does not include a comprehensive list of all power module specifications; complete performance specifications and supplemental characteristics for all power modules are in the Agilent 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 modules simultaneously — from a single PC, adding enhanced data visualization and management.
