Measuring current within a circuit enables optimization of system performance. This optimization may target operating efficiency — critical for mobile, portable, and wearable devices — or the characterization of switching behavior in wide‑bandgap (WBG) semiconductors, where transition times can be on the order of hundreds of picoseconds. Current measurement is also central to double‑pulse testing, where the interaction between the switching device and magnetic components such as transformers and inductors must be evaluated to understand switching loss, hysteresis behavior, and magnetic device loss models.
High‑bandwidth current measurements further support active current sharing across multiple phases, revealing dynamic behavior that would otherwise remain hidden. They also provide insight into internal details of integrated components such as DC/DC converter modules. In addition, resistors serve as the dissipative element in Picotest transient load steppers, such as the 2000A/ns S2000, where bandwidth and insertion inductance directly affect performance. The Picotest load cells and the current shunt resistors will converge, using the same resistor technology to achieve both applications, while minimizing the inductance of both.
