Power Supply Load Step Response Testing with Siglent

One method of quickly determining stability is to use a load step response with Siglent.
In this test, a DC electronic load is used to provide a current load that steps from a low current draw to a higher value in a short period of time. By directly measuring the voltage and current output of the supply with the stepped load, we can visually observe the recovery of the power supply feedback loop and make changes to the design to optimize the response.
