Keysight Technologies recently added two source/measure units (SMUs) to its N6700 Series modular power systems. The N6785A two-quadrant SMU is for battery drain analysis. The N6786A two-quadrant SMU is for functional test. Both SMUs provide power output up to 80 W.
The two new SMUs expand the popular N6780A Series SMU family by offering up to 4× more power than the previous models. The new models offer superior sourcing, measurement, and analysis so engineers can deliver the best possible battery life in their devices. The N6785A and N6786A SMUs allow engineers to test devices that require current up to 8 A, such as tablets, large smartphones, police/military handheld radios, and components of these devices.
The N6780A Series SMUs eliminate the challenges of measuring dynamic currents with a feature called seamless measurement ranging. With seamless measurement ranging, engineers can precisely measure dynamic currents without any glitches or disruptions to the measurement. As the current drawn by the device under test (DUT) changes, the SMU automatically detects the change and switches to the current measurement range that will return the most precise measurement.
When combined with the SMU’s built-in 18-bit digitizer, seamless measurement ranging enables unprecedented effective vertical resolution of ~28-bits. This capability lets users visualize current drain from nA to A in one pass. All data needed is presented in a single picture, which helps users unlock insights to deliver exceptional battery life.
The new SMUs are a part of the N6700 modular power system, which consists of the N6700 low-profile mainframes for ATE applications and the N6705B DC power analyzer mainframe for R&D. The product family has four mainframes and more than 30 DC power modules, providing a complete spectrum of solutions, from R&D through design validation and manufacturing.
