A DC electronic load with two channels and a built-in scope can capture and analyze cross-regulation. Power supplies with multiple voltage rails will have cross-regulation. It is important to characterize the cross-regulation to ensure that it does not affect the device. In the past, this measurement required multiple instruments. Today, a single instrument the EL34243A bench electronic load with a built-in scope mode can generate a unique dynamic load and capture the effects on adjacent voltage rails.
