The Keysight B2901A Precision Source / Measure Unit (SMU) is a 1-channel, compact and cost-effective bench-top SMU with the capability to source and measure both voltage and current. It is versatile to perform I/V (current vs. voltage) measurement easily with high accuracy. Integration of 4 quadrant source and measurement capabilities enables I/V measurement simply and easily without configuring multiple instruments. The wide coverage of 210 V, 3 A DC/10.5 A pulse with a single instrument minimizes the investment. Minimum 100 fA/100 nV measurement resolution support accurate characterization of DUT. The superior 4.3'' color display and various view modes improve productivity for test, debug and characterization with intuitive operation.
