N6781A

The Keysight N6781A is a source / measure unit (SMU) designed specifically for the task of battery drain analysis. Whether the device under test (DUT) is an eBook reader, MP3 player, mobile phone, or pacemaker, the N6781As seamless measurement ranging, programmable output resistance, and auxiliary DVM combine the best set of advanced features on the market for battery drain analysis. When used with the 14585A Control and Analysis software, the N6781A becomes an even more powerful battery drain analysis solution, offering additional insights into your measurements.

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 30 different DC power modules, ranging in capability from basic to high precision, and in power from 20â’300 W.

Key features
> For use with the N6700 Series mainframes (USB, LAN (LXI-C), GPIB): Low profile MPS or DC Power Analyzer
> DC output ratings: 20 V, ±1 A or 6 V, ±3 A, 20 W
> Voltage accuracy: 0.025% + 1.8 mV
> Ripple and noise: 12 mV
> Up and down-programming with resistive load typically 20 ms
> Overvoltage, overcurrent, and overtemperature protection
> Modules can operate at lower output power to stay within mainframe rating
> Modules include a quick disconnect connector

Other features and benefits
> Glitch-free sourcing and measurement ” change output and measurement ranges without any glitches
> Two-quadrant operation ” perform as a voltage or current source or as a CV or CC electronic load
> Four current measurement ranges ” precisely capture the current levels of the DUT during different modes of operation
> Excellent transient response ” keep voltage or current stable during high-speed load changes
> Fast modulation of DC ” create waveforms up to 100 kHz to stimulate or load down the DUT
> High-speed digitized measurements ” capture / view the power consumption of the DUT up to every 5 µs with built-in 200 kHz digitizer
