The Keysight N6705C is a DC power analyzer mainframe at the heart of the N6700 Modular Power System family. It combines 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 that sources and measures DC voltage and current into a device under test. Keysight positions it as an entirely new instrument category for R&D engineers, with all sourcing, loading, and measurement functions available directly from the front panel.

The N6705C is intended for R&D testing and design validation. Engineers use it to gain insight into a device's power consumption without writing code, to set up and view critical turn-on and turn-off sequences, to control DC bias supply or electronic load ramp-up and ramp-down rates, and to generate DC bias transients and disturbances. It can capture inrush current by triggering the integrated oscilloscope on the output's on/off key, and it can log current and power consumption over seconds, minutes, hours, or days to capture anomalies. While designed primarily as an R&D bench tool, 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. 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 DC power and electronic load modules. The N6705C is the DC power analyzer mainframe ordered together with modules as separate items, while the N6715C is the build-to-order version shipped fully assembled with one to four modules installed. Both share 600 W of total available mainframe power and the same module catalog.

Modules fall into several series: basic DC power modules, high-performance autoranging modules, precision modules, application-specific source/measure units, and electronic loads. Each module installs into one slot, except higher-power modules such as the N6753A–N6756A, N6763A–N6766A, N6785A–N6786A, and N6792A, which occupy two slots.

Each model in the family below links to its own dedicated product page with condition-matched pricing for new units. Select the mainframe or module that fits your configuration; the comparison table that follows summarizes the key ratings for each.

The N6705C is the mainframe-plus-modules configuration: you order the N6705C mainframe and choose one to four modules separately, then assemble the system yourself. It provides four module slots, 600 W of total available output power, and full front-panel operation of the integrated DMM, oscilloscope, arbitrary waveform generator, and data logger functions.

The module series differ chiefly in performance 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 N6790 electronic loads offer 100 W and 200 W modules with constant voltage, current, resistance, and power modes. The comparison table below lists each model's output ratings and key characteristics; consult a model's own row for the functions it provides.

Product Core & Specifications

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

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

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

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

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

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.

Recommended pairing: add the BV9200B PathWave BenchVue Advanced Power Control and Analysis Software to control up to four mainframes and as many as 16 installed modules from a single PC.
