Jetperch Unveils Third-Generation Joulescope JS320 Energy Analyzer for Low-Power Engineering

Jetperch Introduces the Joulescope JS320

In an exciting development for engineers working on low-power embedded systems, Jetperch LLC has recently launched the latest addition to its Joulescope line, the JS320. This third-generation precision DC energy analyzer promises to take device optimization to new heights, particularly for applications where energy efficiency and battery life are crucial.

The JS320 builds upon the solid foundation laid by its predecessors, the JS110 and JS220 models, with significant advancements specifically aimed at improving low-current accuracy and current range-change measurements. Leveraging a redesigned internal measurement path, the JS320 empowers engineers to better analyze and tweak systems that predominantly remain in sleep mode, waking only briefly for tasks such as sensing, processing, and communication.

According to Matt Liberty, the founder of Jetperch and the mind behind the Joulescope series, the JS320 is tailored to focus on the key metrics that are integral for modern low-power devices. “Devices often have long periods of inactivity, awakening only for short durations. During these times, factors like offset stability, leakage currents, range-change behavior, and time-domain response can significantly impact battery life estimates,” Liberty explained. The JS320 addresses these concerns, enabling engineers to make more informed decisions in their designs.

This innovative tool measures current from mere nanoamps all the way to several amps, while concurrently capturing voltage data. The ability to compute power, energy, and charge in real time allows engineers to estimate battery longevity, optimize firmware, validate hardware design choices, and ensure that power supply requirements align with device specifications. The incorporation of advanced features, such as improved offset stability, reduced leakage currents, and a higher-quality 24-bit ADC, reflects Jetperch's commitment to providing accurate and detailed analysis.

Moreover, the JS320 is enhanced with the proprietary Enwavify™ v2 technology, designed to specifically handle current range changes more efficiently. This advancement is particularly beneficial for battery-operated IoT devices, BLE technologies, sensors, energy-harvesting products, and more. In scenarios where even minute measurement inaccuracies can skew battery life estimates, the enhanced measurement capabilities of the JS320 mean that engineers can work with greater confidence.

The Joulescope JS320 is not just about accuracy; it aims to maintain the user-friendly interface that has become a hallmark of the Joulescope brand. Jetperch continues to ensure that simplicity and accessibility are at the forefront, allowing engineers to focus on innovation rather than getting bogged down by complicated setups.

Already available for pre-order, the JS320 is anticipated to ship starting June 23, 2026. For over a decade, Jetperch has been at the cutting edge of energy analysis technology, supporting engineers to refine their designs and improve energy efficiency.
