Keysight N6701C – Low Profile Modular Power System Mainframe (600W)

• Mainframe only – modules sold separately
• 600W maximum total output power
• Four module slots
• Over 30 modules available (power supply, load, SMU)
• Ideal for ATE systems in R&D, design validation, and manufacturing

The Keysight N6700 Low-Profile Modular Power System (MPS) is a 1U (rack unit) high, multiple-output programmable DC power supply or electronic load system that enables test system integrators to optimize performance, power, and price to match test needs.

The Keysight N6700 MPS gives test system designers the flexibility to mix and match from over 30 different DC power modules to create a 1- to 4-channel DC power system or electronic load system optimized to meet specific test requirements. Test system engineers can invest in high-performance outputs where speed and accuracy are needed or purchase basic performance outputs for simple DC power requirements, or an electronic load is required for power supply testing.

Several versions available

Keysight offers several versions of its N6700C modular power system. Each model has four module slots and a 1U rack height but provides a different maximum power output.

• N6700C – 400W
• N6701C – 600W
• N6702C – 1200W

Connectivity

The N6700 MPS comes standard with GPIB, USB 2.0, and 10/100 Base-T ethernet LAN interfaces. While GPIB is best suited for use with existing systems, Keysight offers USB and LAN to allow you to take advantage of the availability, speed, and ease of use of common computer industry-standard interfaces. The N6700 is fully compliant with the LXI Class C specification.

Each DC power module or electronic load can be individually set to turn on or to turn off with a delay. By adjusting the delay times and then commanding the N6700 to turn on, you can set the N6700 modules to sequence on in a particular order. The same sequencing capability is available to shut down the modules in a particular order.

For applications that require more than four DC power or electronic load modules to be sequenced, this output sequencing can be extended across multiple N6700 mainframes. When the I/O ports on the rear panel of the main-frames are wired together, a pair of synchronization signals can be sent between mainframes, allowing the output sequences of all mainframes to be synchronized. This capability is supported on N6700C, N6701C and N6702C mainframes.

Series operation

To increase available voltage and power, similarly rated outputs can be operated directly in series on power supply modules.

Easy Parallel Operation With Virtual Channels

To increase available output power and current, identical outputs can be operated in parallel. To simplify parallel operation for applications requiring currents greater than any single output can provide, the N6700 offers virtual channels, a firmware-based feature that allows the N6700 system to treat up to 4 channels as a single, synchronized channel. Once configured, all functions (sourcing, measurements, triggering, protection, and status monitoring) behave as if there is 1 channel of up to 4 times the capacity of a single channel without writing a single line of code to manage the interaction and synchronization of the paralleled power supplies or electronic loads.

Virtual channel capability is available from the front panel when operating the N6700 manually or via computer control.

Each mainframe has 4 module slots to hold modules. Each module occupies one module slot, except for the N6753A-N6756A, N6763A-N6766A, N6785A-N6786A and N6792A which occupy two module slots.

Often, a DUT requires a single high-power DC source and several very low-power DC sources. Since the DUT does not require full power to all outputs, you may choose to save money configuring a system where the sum of the power modules installed in a mainframe exceeds the total power available from the mainframe. In this case, the power management features of the N6700 allow you to allocate mainframe power to the outputs where it is needed, achieving maximum asset utilization and flexibility. This feature provides safety from unexpected and dangerous shutdowns that can occur with power systems without power management when operated in a similar way.

For example, if your DUT requires 280 W on its main input and 10 W each on three auxiliary inputs, you can configure a system consisting of one 300 W DC module and three 100 W DC modules. Even though the sum of the module power is 600 W, you can still use the N6700C 400 W MPS mainframe. Thanks to the power management feature, you can allocate the full 300 W to the 300 W module while you allocate only 33 W to each of the 100 W modules.

Note that if you install one of the new 500 W modules in an N6700C 400 W MPS mainframe, you cannot run this module at its full-rated output power.

For basic DC applications – with voltages up to 150V

The Keysight N6730, N6740, and N6770 Series of DC power modules provide programmable voltage and current, measurement and protection features at a very economical price, making these modules suitable to power the DUT or to provide power for ATE system resources, such as fixture control.

N6750 high-performance series

For applications where the power supply plays a critical role – with available power up to 500 W

The Keysight N6750 Series of high-performance, auto-ranging DC power modules provides low noise, high accuracy and programming speeds that are up to 10 to 50 times faster than other programmable power supplies. In addition, Keysight has, for the first time, included high-speed test extensions in general-purpose power supplies. The high-speed test extensions offer an oscilloscope-like digitizer that simplifies system configuration and increases measurement accuracy when viewing high-speed transient or pulse events within the DUT. In addition, auto-ranging output capabilities enable one power supply to do the job of several traditional power supplies.

N6760 Precision Series

For applications where precision is required – with available power up to 500 W

The Keysight N6760 Series of precision DC power modules provides precise control and measurements in the milliampere and microampere region with the ability to simultaneously digitize voltage and current and capture those measurements in an oscilloscope-like data buffer.

N6790 Electronic Load Series

The new Keysight N6790 Series Modular Electronic Loads offer a 100W module and a 200W module each in a 1U footprint. Four different user operation modes are available: constant voltage, constant current, constant resistance, and constant power. With a high, accurate measurement system and digitizing capabilities, users can easily gain insight into their power supply test. Also, the new series offers a powerful, built-in arbitrary waveform generator that allows users to emulate complex dynamic load waveforms. This is a must-have for any serious power system designer and test engineer.
