The Keysight N6761A is a 50 W precision DC power module that provides low noise, and 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. For leakage current or sleep-mode current measurements, add option 2UA for measurement capability down to 1 μA.

This module is used in both the small, multiple output 1U high N6700 Low-Profile Modular Power System (for ATE systems) and the multiple output N6705 DC Power Analyzer (for bench testing). GPIB, LAN, USB, and LXI compliance are standard. Select from more than 20 different DC power modules, ranging in capability from basic to high precision, and in power from 20 - 500 W.

Precision DC Power Module (50V/1.5A/50W)

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.

Low noise output

Careful attention has been paid to this design to ensure low normal mode noise (ripple and peak-peak) as well as low common mode noise. While all DC power modules are switching power supplies, the N6750 high-performance auto-ranging DC power modules, the N6760 precision DC power modules, and the N6780 Source Measure Units are switching power supply designs that outperform most linear power supplies on the market.

Fast voltage changes

When it comes to speed, the N6750 high-performance autoranging DC power modules, the N6760 precision DC power modules, and the N6780 Source Measure Units achieve performance unlike a typical DC power supply. Thanks to an active down-programming circuit to rapidly pull down the output when lowering the output voltage, these power modules can rapidly program both up and down in voltage. Changing voltage from 0 V to 50 V, or 50 V to 0 V for example, can be accomplished in less than 1.5 milliseconds.

Note that for smaller voltage changes, from 0 V to 5 V or 5 V to 0 V for example, the programming speed is less than 200 microseconds. These output speeds allow the N6750/60/80 to give maximum system through-put when your test calls for frequent changes in power supply voltage settings.

Autoranging for flexibility

The N6750 high-performance auto-ranging DC power modules and the N6760 precision DC power modules give you even more flexibility by providing autoranging outputs. This autoranging capability provides maximum output power at any output voltage up to 60 V. This allows one power supply to do the job of several power supplies, because its operating range covers low voltage, high current as well as high voltage, low current operating points.

For example, the N6755A high-performance, autoranging DC module, rated at 20 V, 50 A, and 500 W can provide full power at:

• 10 V @ 50 A (= 500 W),
• 20 V @ 25 A (= 500 W),
• 15 V @ 33 A (= 500 W),
• or anywhere in between

Therefore, this 500 W autoranging power supply, due to its extended voltage and current range, can produce voltage and current combinations in the range of a 1000 W non-autoranging power supply.
