The Keysight B2901BL is a single-channel precision Source/Measure Unit (SMU) that sources and measures voltage and current with exceptional resolution. This benchtop instrument delivers 1 pA current measurement resolution and 100 nV voltage measurement resolution, making it ideal for characterizing semiconductors, passive components, and low-power devices. The 4-quadrant source architecture enables bidirectional current and voltage sourcing across a 21 V / 1.5 A range, while integrated arbitrary waveform generation and digitizing capabilities support complex stimulus-response testing.
