Fast transient response

With fast transient response, the R&S

NGU is able to quickly stabilize the output volt-

age upon a step change in the load current.

Load transient recovery time can be switched between 30

s ("Fast Transient

Response" = "ON") or 100

s ("Fast Transient Response" = "OFF") for the output volt-

age to recover and stay within 20 mV of the nominal output voltage follows by a step
change in the load current.

1. Press [Settings] key.

The R&S

NGU displays the device/channel menu window.

2. Select the channel tab to apply fast transient response.

The R&S

NGU displays the channel menu.
