Unlike any other product available today, the N6781A and N6785A offer the features necessary to accurately capture the power consumption of portable, battery-powered devices from 20 W to 80 W. When used with the Keysight BV9200B and BV9201B software, the N6781A and N6785A become an even more powerful battery drain analysis solution offering even further insights into your measurements. Whether the DUT is an e-Book reader, MP3 player, mobile phone, “phablet,” tablet, or pacemaker, the N6781A and N6785A’s seamless measurement ranging, programmable output resistance, and auxiliary DVM combine to be the only solution on the market that helps you deliver exceptional battery life.

•  Deliver exceptional battery life with insight into your device’s power consumption you can get nowhere else
•  Measure all modes of operation simultaneously, no need to change measurement ranges with seamless, dynamic measurements down to nA and μV
•  More accurately the late performance of a battery with an internal resistance of a battery using the programmable output resistance of the N6781A and N6785A.
•  Perform tests with the actual battery – monitor your battery’s voltage with the built-in auxiliary voltage measurement system while using the SMU’s ammeter mode (zero-burden current shunt) to perform real-world battery rundown tests
•  Easily make sense of your measurements – scope, data logger, and complementary cumulative distribution function (CCDF) statistical analysis all help you understand what you’ve measured

The ability to modulate the output up to 100 kHz along with 2-quadrant operation makes the N6782A and N6786A a perfect fit for advanced functional tests of a variety of devices such as DC/DC converters, power management units, power amplifiers, and power management ICs (PMICs) from 20 W to 80 W.

Stimulate the input stage of your DUT with fast sourcing and waveforms up to 100 kHz using the advanced arbitrary waveform generation feature.

The output stage can be loaded down and measured with the electronic load capabilities of the N6782A and N6786A, providing a total test solution.

The N6783A requires one of two options: N6783A-BAT or N6783A-MFG.

The Keysight N6783A-BAT battery charge/discharge module is a basic, 2-quadrant DC power module designed to be used by mobile device designers. Its 2-quadrant operation allows it to act as a programmable power supply to charge the battery or as a programmable electronic load to discharge the battery, all in one instrument.

The Keysight N6783A-MFG mobile communications DC power module offers advanced features specifically for testing battery-powered (mobile) devices in manufacturing or automated test environments.

General-purpose applications can span many different industries and many different devices under test. The N6784A SMU’s glitch-free operation ensures safe usage with the DUT during output and measurement range changes, even with capacitances of up to 150 μF. This enables use with a wide variety of DUTs. Its 4-quadrant operation enables it to act as a bipolar power supply or a bipolar electronic load, for added versatility.

•  Glitch-free operation ensures that during programmed output or measurement ranges changes, the N6784A’s output voltage and current remain steady and the DUT remains damage-free.
•  Four current programming ranges (3 A, 300 mA, 100 mA, and 10 mA) enables the N6784A to be a precise current source or electronic load down to μA.
