Fast Transient Response

With fast transient response, the R&S

NGL/NGM is able to quickly stabilize the output

voltage 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.

Figure 6-5: Transient response graph

1. Press [Settings] key.

The R&S

NGL/NGM displays the device/channel menu window.

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

The R&S

NGL/NGM displays the selected channel menu.
