The Keysight (Agilent) N2820A is a high-sensitivity AC/DC current probe delivering simultaneous low-gain and high-gain measurement channels for precise current characterization across dynamic ranges exceeding 20,000:1. Engineered for battery-powered devices and integrated circuits, this probe captures sub-milliampere current levels with sensitivity while supporting charge measurements over time on compatible oscilloscopes.
