Power integrity test

Ensure power integrity in your electronic design

The power delivery network (PDN) provides and delivers the required DC power to all active components on the board. As disturbances on power rails can cause serious impairments to the performance of the used ICs and the overall system, Power Integrity is a paramount requirement in board and system design.

Rohde & Schwarz provides a wide range of tools to efficiently analyze unwanted disturbances on your power rails and to identify their root cause. Our powerful tools also help you to verify the entire power delivery chain from the voltage regulator module (VRM) all the way to the supplied component.
