The Agilent/Keysight SL1045A is a high-performance system component within Keysight’s Scienlab Dynamic DC Emulator (DCE) series, specifically designed for automotive applications such as emulating batteries and other components for electric vehicles. While the initial product description positions it as a “system local oscillator,” further investigation reveals that the SL1045A is a modular, rack-mounted system designed for power emulation and regenerative testing, operating in a two-quadrant mode as both a power source and a regenerative electronic load. This unit is part of a broader family of test systems for HEV/EV and grid applications.
