Joulescope JS220+: Precision Energy Analyzer

The LIMITED EDITION Joulescope JS220+ is a variant of the JS220 redesigned for exceptional performance, temperature stability, and ±1 nanoamp accuracy when measured at ±20 nA. The JS220+ operates identically to the JS220, and the JS220+ provides the same, best-in-class high-dynamic current range measurement as the JS220. A JS220+ enables world-class accuracy for measurement challenges including: In-circuit leakage measurement for market-leading low-power ICs. Capacitor leakage measurement, including super-capacitors. Charge, energy, and battery life estimation for leading energy-harvesting and extreme low-power systems. Many low-measurement instruments based on transimpedance amplifiers (feedback ammeters) can measure down to fA (1e-15 A). However, these instruments are typically specified for a maximum capacitance, often around 10 nF (1e-8 F), often four orders of magnitude below what is needed for in-circuit measurements. The JS220+ is inherently stable at all capacitances. The JS
