The Keysight B2901BL is a single-channel precision source/measure unit (SMU) delivering integrated 4-quadrant sourcing and measurement in a compact benchtop form factor. It performs DC and pulse characterization across voltage, current, and resistance without requiring instrument reconfiguration. The 4.3-inch TFT color display with graphical and numerical modes supports real-time I/V analysis, while comprehensive connectivity—USB 2.0, LAN, GPIB, and digital I/O—enables both local and remote control via SCPI commands.
