Keysight B2901C Precision Source/Measure Unit

Overview

The Keysight B2901C is a high-performance, single-channel precision Source/Measure Unit (SMU) offering accurate and versatile voltage and current sourcing and measurement capabilities. It supports voltages up to ±210 V, currents up to ±3 A DC, and pulsed currents up to ±10.5 A, making it ideal for diverse IV measurement tasks. Its fine resolution (100 fA current measurement, 1 µV voltage sourcing) allows precise characterization of semiconductors, discrete components, photovoltaic cells, and other electronic devices.

The device features a 4.3-inch color LCD graphical interface that allows intuitive setup and data viewing directly from the front panel. Four-quadrant functionality simplifies complex measurement setups by replacing multiple instruments with one compact unit. Remote control via USB, LAN, GPIB, and available software solutions like Keysight's PathWave BenchVue enable seamless integration into automated test environments.
