The Keysight B2900B/BL Series Precision Source/Measure Units are compact and cost-effective benchtop Source/Measure Units (SMUs) with the capability to source and measure both voltage and current. These capabilities make the B2900B/BL Series SMU ideal for a wide variety of IV (current versus voltage) measurement tasks that require both high resolution and accuracy.
The B2900B/BL Series SMU has a voltage maximum of ±210 V, a current maximum ±3 A DC, and ±10.5 A pulsed sourcing capabilities. With a precision minimum of 10 fA/100 nV sourcing and measuring resolution, a color LCD graphical user interface (GUI) and several task-based viewing modes will improve your productivity for test, debug, and characterization.
The B2900B/BL Series SMU offers superior measurement throughput and supports conventional SMU SCPI commands for easy test code migration. These features improve efficiency and lower the cost of ownership when integrating the SMUs into systems for production test.
