Agilent/Keysight B2902B

The Keysight B2902B is a dual-channel precision source/measure unit (SMU) for high-accuracy voltage and current sourcing and measurement across four quadrants. Designed for research, development, and production characterization, this benchtop instrument delivers 1 µV voltage source resolution and 1 pA current source resolution, with measurement capabilities reaching 100 nV and 100 fA respectively at 6½ digits. The B2902B sources up to ±210 V and ±3 A DC (±10.5 A pulsed) with a maximum output power of 31.8 W, enabling comprehensive device and material testing.
