Power supplies and electronic loads are a fundamental component of every test system in industries including aerospace and defense, consumer electronics, computers and peripherals, communications, semiconductor and automotive electronics. Today’s complex automatic test equipment (ATE) systems often require multiple power sources or electronic loads. Test system designers are challenged to keep costs down by reducing rack space occupied by these multiple power supplies or electronic loads and to continually increase test system throughput. The Keysight Technologies, Inc. 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.

N6700 System Features

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.

Small size

The Keysight N6700 MPS uses an advanced switching power supply design that fits within 1U of rack

space (1.75 in./44 mm). It has side air vents (no top or bottom air vents) so other instruments can be

mounted directly above or below it. (Requires rack mount kit; see ordering information.)

Built-in measurement of voltage and current

The N6700 modules come standard with built-in measurement of voltage and current to simplify wiring and design of an ATE system.

Protection features

Each N6700 module is protected against over-voltage, over-current, and over-temperature. A fault condition in one module can be detected within 10 microseconds by other modules so that they can be quickly shut down to avoid hazardous conditions on your device under test (DUT).

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.

Security

When used in systems running GPIB, the LAN and/or USB interfaces can be disabled for extra security. Also, all non-volatile RAM data and settings can be cleared from the front panel.

Control from any browser

The N6700 can be controlled via a standard web browser. The N6700 contains a web server that provides web pages for monitor, control, and setup of the MPS.

Output Sequencing

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.

Programmable Slew

For some applications, like inrush limiting or powering rate-sensitive devices, it is necessary to slow down and control the speed of the power supply to maintain a specific voltage slew rate. The N6700 provides programmable voltage slew rate, so that you can easily control the speed at which the output slews from one voltage to another. You can set the speed of a voltage change anywhere from its maximum up/down programming speed to its slowest change of up to 10 seconds. Programmable voltage slew is available from the front panel when operating the N6700 manually or via computer control. For the electronic load family, slew control is available for voltage or current or resistance or power.

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.
