Keysight Technologies U2722A/U2723A USB Modular Source Measure Unit Data SheetIntroduction Voltage and current programming and readback The Keysight Technologies, Inc. U2722A/U2723A USB modular source measure unit is more than just a power supply it has fast response time, and voltage and current programming/readback with high accuracy measurement capabilities. The U2722A and its enhanced version, the U2723A, are capable of four-quadrant operation, acting as a current source as well as the current sink (load) with both polarities of the output voltage. The U2723A offers additional features such as embedded test scripts to simplify automated testing, and faster rise time to help improve throughput during mass testing of semiconductor components.
