The Keysight N6705C is a DC Power Analyzer mainframe at the heart of the N6700 Modular Power System family. It sources and measures DC voltage and current into a device under test, combining one to four DC power supply or electronic load modules with the functions of a DMM, oscilloscope, arbitrary waveform generator, and data logger in a single integrated instrument. All sourcing or loading and measurement functions are presented from the front panel without requiring any programming, positioning the Keysight N6705C as an entirely new instrument category for R&D engineers.

The N6705C is intended for R&D testing and design validation. From the front panel an engineer can gain insight into a device's power consumption without writing code, set up and view critical turn-on and turn-off sequences, measure and display voltage and current versus time to visualize power into the DUT, control DC bias-supply or electronic-load ramp-up and ramp-down rates, and generate DC bias transients and disturbances as arbitrary waveforms. 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. It can also log current and power consumption over seconds, minutes, hours, or days to capture anomalies. 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 test development, DUT troubleshooting, and visualizing results as tests execute.

ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit we sell 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

Keysight Technologies traces its measurement heritage to Hewlett-Packard, whose test-and-measurement business was spun off as Agilent Technologies in 1999. Agilent's electronic measurement division then became Keysight Technologies in 2014, the brand under which this instrument family is produced today.

Compare Other Models in This Series

The Keysight N6700 Modular Power System family is built around a mainframe with four module slots and a selection of more than thirty interchangeable DC power and electronic load modules. The N6705C DC Power Analyzer mainframe has four slots and 600 W of total available power, accepting one to four modules ordered together as separate items; the N6715C is the same system ordered as a fully assembled, build-to-order instrument with one to four modules pre-installed. Both share 600 W of total available mainframe power and the same module catalog. The same modules also run in the N6700-series low-profile mainframes used for ATE, allowing test correlation between bench and manufacturing setups. The N6700 Low-Profile Modular Power System is a 1U-high, multiple-output programmable DC power supply system that lets test-system integrators optimize performance, power, and price to match their test needs, while the N6705C DC Power Analyzer brings the same modules to the R&D bench.

Module capability depends not only on the module's own hardware but also on the mainframe in which it is installed; modules placed in an N6705C DC Power Analyzer gain front-panel scope view, arbitrary waveform generation, and data logging that are not present in the lower-profile N6700C-series mainframes. Modules are grouped into series by role: basic DC power modules (N6730, N6740, N6770), high-performance autoranging modules (N6750), precision modules (N6760), application-specific source/measure units (N6780), and DC electronic loads (N6790). You can invest in high-performance or precision outputs where speed and accuracy matter, or basic outputs for simple DC requirements, and swap or add modules as test needs change.

Each model in the family below links to its own dedicated product page with condition-matched pricing for pre-owned units. Select the mainframe or module that fits your configuration, and review its individual page for the specifications and options that apply to that pre-owned unit; the comparison table that follows summarizes the key ratings for each.

The N6705C is the four-slot DC Power Analyzer mainframe at the center of the system, providing four module slots, 600 W of total available output power, front-panel binding posts rated 20 A per post, 4 gigabytes of internal non-volatile storage, a built-in real-time clock, power management that allocates mainframe power to the outputs that need it, and full front-panel operation of the integrated DMM, oscilloscope, arbitrary waveform generator, and data logger functions.

The modules differ chiefly in performance class and rating. Basic DC power modules cover 50 W, 100 W, and 300 W outputs up to 150 V and up to 20 A. High-performance autoranging modules span 50 W to 500 W up to 60 V and up to 50 A and add autoranging outputs that deliver maximum power across a range of voltage and current combinations. Precision modules likewise reach 500 W and add precise control and measurement in the milliampere and microampere region with simultaneous voltage and current digitizing. Application-specific source/measure units provide up to 80 W with two- or four-quadrant operation, and the application-specific N6783A modules target battery and mobile-communications testing at 18 W to 24 W. The N6790 electronic loads offer 100 W and 200 W input ratings with constant voltage, current, resistance, and power modes, up to 60 V and 40 A. The ≥300 W high-performance and precision modules and the N6792A load each occupy two of the mainframe's four slots.

Performance features also vary by series: autoranging output is available on the high-performance and precision modules; simultaneous voltage-and-current scope traces and data logging are offered on the precision, SMU, and N6790A modules; and high-speed test extensions are standard on the precision and SMU modules but an option (054) on others. The comparison table that follows lists each model's ratings and key characteristics side by side; consult a model's own row for the functions it provides.

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

Product Core & Specifications

DC Power Module Key Performance Specifications

Important: The N6705C mainframe has four module slots and holds one to four DC power or electronic load modules; modules are ordered separately and at least one module is required for the DC power analyzer to operate.

Important: This is a modular system: the DC power and load modules (N6731B–N6792A) are not standalone instruments and require an N6700C, N6701C, N6702C, or N6705C mainframe (sold separately) to operate.

Important: Each module occupies one module slot, except for the N6753A–N6756A, N6763A–N6766A, N6785A–N6786A and N6792A, which each occupy two module slots.

Important: Each N6705C / N6715C mainframe has 4 module slots and provides 600 W total available output power. If the sum of the installed modules' power exceeds the mainframe's available output power, use Keysight's power management capability to allocate mainframe power to the outputs where it is needed.

Important: Front-panel binding posts are rated for 20 A per post; modules rated above 20 A, such as the N6753A or N6792A, require high-current wiring routed through the rear panel.

Important: Output terminal isolation: no output terminal may be more than ±240 VDC from any other terminal or chassis ground.

Important: Series and parallel operation: the maximum series operation is 240 V, and the maximum rated parallel operation is 100 A per N6705 mainframe.

Important: Output current is derated 1% per °C above 40 °C ambient temperature.

Important: Arbitrary waveform generation, scope view, and the related N6705 oscilloscope measurement capabilities apply only when the power modules are installed in a Keysight N6705 DC Power Analyzer.

Important: The Keysight N6791A and N6792A Electronic Load Modules are not supported on the previous Keysight mainframes N6700B, N6701A, N6702A, N6705A, and N6705B.

Important: For the N6702C mainframe, an AC mains rated at 100-180 VAC cannot supply enough current to power the mainframe at its full rated power; internal circuits limit the module power to 600 W maximum at that input.

Important: Option 760 (Output Disconnect/Polarity Reversal Relays) is not available on Models N6741B, N6751A, N6752A, N6761A, N6762A, and N6781A–N6786A, and it limits the output current to 10 A maximum on Models N6742B and N6773A.

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

Important: Keysight 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 time; when the internal temperature exceeds its safe limit, the output latches off and a protect clear is required to resume operation.

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 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: When ordering a mainframe and modules separately (Step 1), an appropriate documentation/line cord option must be selected; each item arrives in a separate box for self-assembly. The N6715C is a build-to-order system shipped fully assembled, and at least one module must be ordered with it.

Important: This data sheet does not include a comprehensive list of all power module specifications; complete performance specifications and supplemental characteristics are in the Keysight N6700 Modular Power System Family Specifications Guide, part number N6700-90001.

Recommended pairing: add the BV9200B PathWave BenchVue Advanced Power Control and Analysis Software, or the 14585A Control and Analysis Software, to control the family's DC power and electronic load modules installed in up to four N6705 mainframes — as many as 16 installed modules — from a single PC. These power, source/measure, and load modules are designed to install in the Keysight N6700C-series mainframes or the N6705C DC Power Analyzer covered in this family.
