U2723A

The Keysight U2723A is a 3-channel USB Modular Source Measure Unit (SMU) designed for precise voltage and current sourcing and measurement. With its 4-quadrant operating capability, each of the three channels can source or sink up to ±20 V and ±120 mA. A defining feature of the U2723A is its embedded test scripting capability, allowing for standalone test sequences of up to 10,000 steps without continuous host PC polling. Operating with high-speed USB 2.0 connectivity, the U2723A is isolated for robust safety and noise reduction, making it ideal for semiconductor characterization, educational laboratories, and high-throughput automated test environments.
