Product Overview

Keysight high-performance modules increase test flexibility with autoranging outputs, providing higher current at more voltages. Autoranging outputs provide the greatest flexibility to keep up with changes to test requirements. Lower noise and higher accuracy are ideal for precise testing. Eliminate the need for an external multimeter with an accuracy of 0.06%. Fast up and down programming allows for quick testing, up to 50 times faster than a conventional power supply.

The N6785A is a source/measure unit (SMU) designed specifically for battery drain analysis of large mobile, battery-powered devices up to 20 V, up to 8 A, up to 80 W.

Deliver exceptional battery life. Only Keysight`s N6780 Series SMUs let you visualize the current drain from nA to A in one pass and one picture unlocking insights to deliver exceptional battery life. Accurately emulate a battery with exceptional sourcing.

Stable, glitch-free sourcing and sinking (charge/eLoad), just like a battery.
Programmable output resistance mimics the battery’s internal resistance.

Make measurements you didn’t think were possible.

Characterize your device’s off-, sleep-, and transmit-mode current in one pass and one picture with Keysight’s exclusive patented seamless measurement ranging technology - no need to make multiple measurement sweeps.
Perform battery rundown tests and characterize how your device performs with an actual battery with the SMU’s ammeter (zero-burden current shunt) mode.
