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 supply or electronic load modules 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 critical 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. It can capture inrush current by triggering the integrated oscilloscope on the output's on/off key. 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.

A complementary low-profile member of the same family is the N6700 Modular Power System (MPS) — a 1U-high, multiple-output programmable DC power supply system built on an advanced switching power supply design that fits within 1U of rack space, letting test system integrators optimize performance, power, and price to match their test needs. Power supplies 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 and functional test.

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 and ready to ship. 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. 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

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.

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, and source/measure series, plus electronic loads, and the same modules are shared between the N6705 bench analyzer and the low-profile N6700 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 comparison table that follows summarizes the key ratings for each.

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 corresponding later-generation pair, the N6705C mainframe and the N6715C build-to-order configuration, likewise share 600 W of total mainframe power and the same module catalog.) The N6705B rear panel also provides access ports to route high-current wiring for modules rated above 20 A.

In the low-profile N6700 line, mainframes are available in 400 W, 600 W, and 1200 W total-output-power tiers, provided by the N6700B (400 W), N6701A (600 W), and N6702A (1200 W). 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 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; the high-performance autoranging modules span 50 W to 500 W up to 60 V and up to 50 A and deliver maximum power across a range of voltage and current combinations, while the precision series further provides dual programming and measurement ranges with 16-bit programming and 18-bit measurement precision, precise control and measurement in the milliampere and microampere region, and simultaneous voltage and current digitizing. The N6780 source/measure units add multi-quadrant operation (two- or four-quadrant), up to 80 W, and highly accurate measurements down to nanoamperes. The N6790 electronic loads offer 100 W and 200 W modules with constant voltage, current, resistance, and power modes.

Output ratings, ripple and noise, and voltage and current programming and measurement accuracy vary by module, and higher-power modules — including the high-performance autoranging and precision modules rated at 300 W or more, as well as the N6785A–N6786A and N6792A — each 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.

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.

Important: The N6705B 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 for the N6753A–N6756A and N6763A–N6766A (high-performance autoranging and precision modules rated ≥ 300 W) and the N6785A–N6786A and N6792A, 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: For modules with outputs rated greater than 20 A (such as the N6753A), high-current wires 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: 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: Maximum series operation is 240 V; maximum rated parallel operation is 100 A per N6705.

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: On the low-profile N6700 mainframes, installing one of the 500 W modules in the 400 W N6700B mainframe may prevent that module from running at its full rated output power.

Important: When configuring a low-profile N6700 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 low-profile 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: 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.

Important: When the N6702A 1200 W mainframe is plugged into a standard AC outlet, it 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: 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.

Recommended pairing: the Agilent 14585A Control and Analysis Software controls up to four N6705 mainframes — up to 16 power modules simultaneously — from a single PC, adding enhanced data visualization and management. The later BV9200B PathWave BenchVue Advanced Power Control and Analysis Software likewise controls up to four mainframes and as many as 16 installed modules from a single PC.
