Joulescope JS220-K001 DC Energy Analyzer

Overview

The Joulescope JS220-K001 is a precision DC energy analyzer designed to measure current and voltage simultaneously across a wide dynamic range. It captures data from nanoamps to amps, making it ideal for power profiling of modern battery-powered and IoT devices. With 2 million samples per second and 300 kHz bandwidth, it displays waveforms like an oscilloscope while providing accurate measurements with minimal impact on the device under test.
