Built on an advanced switching power supply design that fits within 1U of rack space, a single mainframe holds one to four modules, and the system lets you mix and match from over 30 different DC power and electronic load modules to create a 1- to 4-channel system tailored to specific test requirements. Test system engineers can invest in high-performance outputs where speed and accuracy are needed, choose basic-performance outputs for simple DC power requirements, or add electronic load modules for power supply testing. The N6700 MPS is designed for automatic test equipment (ATE) systems in R&D, design validation, and manufacturing, where designers must reduce the rack space occupied by multiple supplies or loads while increasing test system throughput. 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. 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. 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 N6700-series mainframes, and all sourcing, loading, and measurement functions run from the front panel without requiring any programming. ValueTronics stocks and holds its own test and measurement inventory in a 20,000 sq ft 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 was then established as Keysight Technologies in 2014, the brand under which this product line is offered today. ## Compare Other Models in This Series The N6700 Modular Power System is a family built around a 1U mainframe and an extensive catalog of interchangeable DC power and electronic load modules. Rather than a fixed-function instrument, it gives test system designers the flexibility to mix and match from over 30 different modules to create a 1- to 4-channel system optimized to meet specific test requirements — investing in high-performance outputs where speed and accuracy are needed, and basic outputs for simple DC power requirements. The catalog organizes modules into distinct series: basic DC power modules (the N6730, N6740, and N6770 ranges), high-performance autoranging modules (N6750 series), precision modules (N6760 series), source/measure units (N6780 series), application-specific modules (N6783A), and DC electronic loads (N6790 series). Mainframes are available in 400 W, 600 W, and 1200 W tiers. Each module occupies one mainframe slot, except the double-wide higher-power modules — the N6753A–N6756A, N6763A–N6766A, N6785A–N6786A, and N6792A — which each occupy two of the four slots. Across the family, 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 provide four module slots, 600 W of total available output power, and the same module catalog. 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. Each new model linked below is its own dedicated product page with condition-matched pricing. Select the specific mainframe or module that fits your configuration to see its availability and price. Across the mainframes, 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 models differ primarily in mainframe power and in module output ratings and performance class. Mainframes provide 400 W (N6700B), 600 W (N6701A), or 1200 W (N6702A) of total available output power, and modules are rated at 50 W, 100 W, 300 W, or 500 W — output power ratings span from 18 W up to 500 W per module across the broader series — with output voltages ranging from 5 V up to 150 V depending on the module. Performance class also separates the series: basic modules cover programmable DC power with standard voltage and current measurement; high-performance autoranging and precision modules add autoranging output capability that delivers maximum power across a range of voltage and current combinations up to 60 V, and the precision series adds low voltage and current ranges with precision measurement in the milliampere and microampere region with simultaneous voltage and current digitizing. High-Speed Test Extensions, output disconnect relays (option 761), and output disconnect/polarity reversal relays (option 760) are available according to each module's row in the options table. The comparison table below details each model's output ratings and key performance specifications.

Maximum series operation is 240 V; maximum rated parallel operation is 100 A per N6705 mainframe. > **Important:** For the N6712A/N6712C 1200 W mainframe, 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. When first turned on, the N6702A/N6702C 1200 W mainframe senses the available AC line power and automatically limits output power to 600 W so the high-power mainframe can be plugged into any standard outlet. An AC mains rated at 100–180 VAC cannot supply enough current to power the N6702C mainframe at full rated power; internal circuits limit module power to 600 W maximum at that input. > **Important:** Output current is limited on some modules when option 760 (Output Disconnect/Polarity Reversal Relays) is installed; option 760 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. > **Important:** Option 2UA (200 µA measurement range) is available only on models N6761A and N6762A. > **Important:** Multi-mainframe output sequencing synchronization is supported on the N6700B, N6701A, and N6702A mainframes; it is not supported on the discontinued N6700A mainframe. The N6791A and N6792A Electronic Load Modules are not supported on the previous Keysight mainframes N6700B, N6701A, N6702A, N6705A, and N6705B. > **Important:** Arbitrary waveform generation, scope view, and the related oscilloscope measurement capabilities apply only when the power modules are installed in a Keysight N6705 DC Power Analyzer. Each N6705C / N6715C mainframe has four module slots and provides 600 W of 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:** N6783A modules cannot be used in series with other N6783A modules or any other N67xx module. When sinking power, the N6784A can operate at its 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 and N6783A application-specific modules are shown for the highest output/measurement range, as these modules have multiple ranges. > **Important:** This page 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. ## About this Pre-Owned unit This is a Pre-Owned (used) unit.
