Transient Load Testing for Power Systems
Regardless of the system architecture, the circuit design, or the power levels involved, transient load current step testing is a critical aspect of power-system design, test, and verification. Transient testing makes it possible to evaluate such aspects as power integrity, power-distribution-network (PDN) validation, voltage-regulation-module (VRM) stability and transient response, noise, large-signal control loop stability, input filter stability, load emulation, thermal test, and package performance.
Picotest’s transient steppers can test very fast load current transitions, at peak and average power levels, using multiple form factors that were previously difficult to accomplish. This includes demanding low-voltage, high-current applications like those found in data centers, AI, graphics, EV, and servers. All of these can be tested for attributes such as crosstalk, thermal performance, and EMI.
