Integrating renewable energy sources, electric vehicles, and storage systems into power grids demands advanced control and monitoring systems. Precise current sensors are a critical component of these systems, essential for ensuring reliable and efficient electricity distribution. Quantum sensors, particularly those based on nitrogen vacancy (NV) centers in diamond, provide a promising solution for high-precision current measurement. This document introduces an innovative method for generating microwave signals using direct digital synthesis (DDS) and field-programmable gate arrays (FPGAs) to drive multiple signals.
