Providing 80 W power output, Model N6785A is used for battery drain analysis, while Model N6786A is used for functional test. Two-quadrant SMUs allow engineers to test devices that require current up to 8 A, such as tablets and large smartphones. With seamless measurement ranging, users can measure dynamic currents without glitches or disruptions to measurement. When combined with SMU's built-in 18-bit digitizer, seamless measurement ranging enables effective vertical resolution of ~28-bits.
