Abstract
Systems and methods provided herein relate to a power system, such as a system for a motor. A digital acquisition unit is configured to receive current sense signals associated with a motor and phase voltage power signals associate the motor. The data acquisition unit includes a module coupled to a first ground and an attenuator circuit coupled to a second ground. The first ground is isolated from the second ground. The phase voltage power signals are provided to the attenuator, and the attenuator provides phase voltage sense signals to the module.
