Transient / Step-Load Testing

Apply a fast, controlled current step to a power rail and capture the voltage response — revealing droop, recovery time and stability margin under real operating conditions.

Works with any oscilloscope. This is a bespoke quote so contact us for a price.

Measuring stability from the load step? See SEPIA

The same load-step setup can also give you loop stability & phase margin, non-invasively, using Picotest’s SEPIA method.
