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 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 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 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. 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 rather than sourced on demand. 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.
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.
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 modules. This modular design lets engineers mix and match over thirty different DC power 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, 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 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 precision series further provides dual programming and measurement ranges with 16-bit programming and 18-bit measurement precision. The N6780 source/measure units add multi-quadrant operation and highly accurate measurements down to nanoamperes.
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. The comparison table that follows summarizes these per-model differences so the correct module can be matched to the application.

| AC input ratings | 100 VAC – 240 VAC; 50/60/400 Hz |
| Power consumption | 1440 VA |

| Net weight (N6705 with 4 modules, typical) | 16 kg / 35 lbs |
| Dimensions (Height / Width / Depth) | 194.7 mm / 425.6 mm / 313 mm (7.665 in. / 16.756 in. / 12.319 in.) |

Important: Front-panel binding posts are rated for 20 A per post; modules with outputs rated greater than 20 A route their high-current wiring through the N6705 rear panel.
Important: The N6705B mainframe holds 1 to 4 DC power modules across 4 slots; modules are ordered separately and at least one DC power module is required for the system to function.
Important: Modules rated ≥ 300 W (N6753A–N6756A high-performance autoranging and N6763A–N6766A precision) 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: 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: 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.
