Measure Leakage And Sleep Currents

Precision low-current measurement requires applying controlled voltage or current to a device while accurately capturing microampere and nanoampere-level responses. The test setup must support low-noise measurement paths, high-resolution instrumentation, and stable electrical connections to detect leakage current and standby current behavior in electronic components.

The measurement workflow involves sourcing voltage or current to the DUT, measuring the resulting current using either a shunt resistor method or a source measure unit, and analyzing the response under powered and unpowered conditions. Accurate results depend on minimizing noise, controlling thermal effects, and configuring measurement ranges and thresholds appropriately for each test scenario.

Low Current Measurement Test Solution

Low-current measurement requires precise sourcing and measurement capabilities with minimal noise and high resolution to detect microampere and nanoampere-level currents. The solution integrates an in-circuit test system with a precision source measure unit and automated test sequencing software. It enables accurate current measurement by providing controlled stimulus, noise filtering, and high-resolution sensing in a single setup. The system also supports automated test sequence generation using a guided workflow, simplifying integration into manufacturing environments. With dual-channel measurement capability and seamless tester connectivity, the solution improves measurement accuracy while reducing test development complexity.
