Agilent/Keysight B2912B

The Keysight B2912B is a dual-channel precision Source/Measure Unit (SMU) delivering 4-quadrant sourcing and simultaneous measurement capabilities for advanced I-V characterization. Each channel functions as both current and voltage source and meter, with output to ±210 V and ±3 A DC (±10.5 A pulsed). Resolution reaches 10 fA and 100 nV across source and measurement paths. The instrument captures transient phenomena at up to 100,000 Sa/s with 10 µs minimum timing intervals, delivering maximum 31.8 W output power. A 4.3-inch color LCD provides graphical and numerical display modes. Connectivity spans GPIB, LAN/Ethernet, USB 2.0, and digital I/O, with support for 2-wire and 4-wire measurement topologies via banana jack inputs. The B2912B integrates with BenchVue, web-based graphical control, Quick I-V Measurement Software, and EasyEXPERT group+ for automated parametric characterization. SCPI command support enables remote operation from PC without custom programming across all interfaces.
