Keysight Technologies N6700 Power System Source Measure Units (SMUs) measure currents accurately down to microampere and nanoampere. These SMUs provide accurate current measurements with seamless ranging, analyze a device and battery with the voltmeter mode, and emulate a battery with stable glitch-free sourcing and sinking. N6700 SMUs feature highly accurate measurements down to nanoamperes while providing operation as a DC current source, electronic load, and DC voltage source. Keysight Technologies N6700 Power System SMUs are designed for use in battery drain analysis, functional testing, and more.
