The Agilent N6705 DC Power Analyzer is 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. 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, since all sourcing, loading, and measuring functions are available directly from the front panel.

The 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.

The same modules also run in the low-profile N6700 Modular Power System (MPS) mainframes used for automated test equipment (ATE). The N6700 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, allowing test correlation and program sharing between R&D and manufacturing. 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 — industries where complex ATE systems often require multiple power sources and where reducing occupied rack space and increasing test throughput are constant pressures.

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.

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 the N6705 DC Power Analyzer, a modular instrument whose mainframe has four slots that accept 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. 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.

As test needs change, different modules can be purchased and swapped into the mainframe, so the system grows over time. The modules are grouped into basic, high-performance autoranging, precision, source/measure, and electronic load series, and 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.

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.

The N6705B is the four-slot DC Power Analyzer mainframe, ordered together with separately boxed modules that you assemble yourself, and it provides 600 W of total available power. Buyers who prefer a fully tested, assembled system can instead order the N6715B build-to-order configuration, which ships as one mainframe with one to four installed modules. The N6705B rear panel also provides access ports to route high-current wiring for modules rated above 20 A. The N6705C is the corresponding "C" generation DC Power Analyzer mainframe, with the N6715C as its build-to-order equivalent; both also provide 600 W of total available power across four module slots, with 4 gigabytes of internal non-volatile storage and a built-in real-time clock.

Alongside the DC Power Analyzers, the family includes the low-profile N6700-series mainframes for ATE, available in 400 W, 600 W, and 1200 W total-output-power tiers — the N6700B/N6700C (400 W), N6701A/N6701C (600 W), and N6702A/N6702C (1200 W) — each holding one to four modules within a single 1U chassis. The N6702A/N6702C 1200 W mainframe senses the available AC line power at turn-on and automatically scales back output power to 600 W so a high-power mainframe can be plugged into any standard outlet. Cross-mainframe output sequencing is supported on the N6700B, N6701A, and N6702A; the corresponding build-to-order low-profile systems are the N6710B/N6711A/N6712A and N6710C/N6711C/N6712C configurations.

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 that deliver maximum power across a range of voltage and current combinations, 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 (two- and four-quadrant) operation and highly accurate measurements down to nanoamperes, ranges down to a 10 microampere current range, and battery emulator/charger and CC/CV load functions, with available power of 20 W to 80 W. The application-specific N6783A modules (N6783A-BAT and N6783A-MFG) provide two-quadrant battery charge/discharge and mobile-device manufacturing test functions at 18 W to 24 W. The N6790 electronic loads offer 100 W and 200 W modules with constant voltage, current, resistance, and power priority modes, programmable slew rates, and ratings up to 60 V and 40 A.

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, along with the N6792A load, occupy two of the four mainframe slots. 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.

N6755A Key Specifications

Product Core & Specifications

Important: Front-panel binding posts are rated for 20 A per post; modules with outputs rated greater than 20 A, such as the N6753A or N6792A, route their high-current wiring through the N6705 rear panel (for an N6705A mainframe, order N6705U-057 to replace the rear panel).

Important: The N6705 mainframe holds 1 to 4 DC power or electronic load modules across 4 slots; modules are ordered separately and at least one module is required for the DC power analyzer to operate.

Important: Each module occupies one module slot, except the N6753A–N6756A and N6763A–N6766A double-wide modules, the N6785A–N6786A SMU modules, and the N6792A load, which each occupy two of the mainframe's four module slots.

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: Installing a 500 W module in a 400 W low-profile mainframe (N6700B / N6700C) may prevent that module from running at its full rated output power.

Important: When configuring a low-profile 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 for proper operation.

Important: If you will be rack mounting an N6700 low-profile mainframe, you must order the rack mount kit (N6709A, or N6709C for "C" generation mainframes); standard rack rails or slides are not compatible with the N6700 because of its 1U size and airflow requirements.

Important: The N6702A / N6702C 1200 W mainframe senses the available AC line power at turn-on and limits output power to 600 W so the high-power mainframe can be plugged into any standard outlet. For the 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. An AC mains rated at 100–180 VAC cannot supply enough current to power the N6702A / N6702C at its full rated power; internal circuits then limit module power 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: 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–N6786A. Option 761 provides output (and sense) disconnect relays. The minimum output turn-on delay increases when a relay option is installed (for the N6755A, from 18 ms to 44 ms with Option 760).

Important: Option 2UA (200 µA measurement range) is available only on Models N6761A and N6762A. High-Speed Test Extensions (option 054) add LIST sequencing and digitizing; they are optional on the basic, high-performance, and 300 W modules and standard on the precision, SMU, application-specific, and load modules.

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. Maximum series operation is 240 V; maximum rated parallel operation is 100 A per N6705.

Important: 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; 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: The Keysight N6791A and N6792A Electronic Load Modules are not supported on the previous mainframes N6700B, N6701A, N6702A, N6705A, and N6705B. Arbitrary waveform generation, scope view, and the related oscilloscope measurement capabilities apply only when modules are installed in an N6705 DC Power Analyzer.

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 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 (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 Keysight 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. On "C" generation systems, 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.
