Joulescope: Precision DC Energy Analyzer

Joulescope™ enables designers, engineers, and makers to quickly and easily optimize the energy consumption and battery life of a target device. Joulescope is designed to automatically handle wide current ranges and rapid changes in energy consumption, while allowing the target device to run normally. Jetperch LLC writes:

Measuring energy consumption during product development is crucial, especially for battery powered and always-on devices. However, measuring energy consumption accurately has been expensive, tedious or error-prone.

Measuring energy consumption during product development is crucial, especially for battery powered and always-on devices. However, measuring energy consumption accurately has been expensive, tedious or error-prone.

Makes the invisible visible:  Joulescope measures current and voltage 2 million times per second with 250 kHz bandwidth.  This high sampling rate makes the power consumption of interrupt service routines, inrush currents and other short events visible.

Easy to use:  Joulescope reports cumulative energy consumption along with real-time current, voltage, and power. The multimeter view clearly shows the most recent value while the oscilloscope view allows you to explore changes over time.  Much simpler and more accurate than anything in its class!

Customizable:  The Joulescope host software is open source on github.  You can also swap the banana jack front panel with front panels that have other connector types!  The front panels are open source on github.  We ❤ open source.

Joulescope’s precision and fast sample rate enabled me to discover unexpected processing, and I reduced my device’s energy consumption by removing this unnecessary processing. Joulescope is now a valuable part of my toolset for debugging and verifying designs.
