3. Activate the "Fast Transient Response" from the menu.
The R&S NGU applies the fast transient response on the operating condition and
displays the "Fast Transient Response" icon on the channel status bar information.
The setting of "Fast Transient Response" affects the output voltage control loop
behavior. See
Chapter 6.2.3.1, "Impedance" , on page 48.
If activated, the focus is on the control loop speed, which is recommended for
resistive loads. In slow transient response, the focus is on the stability and should
be preferred for capacitive or inductive loads.
6.2.3 Output
The "Output" menu provides the settings for output impedance , output delay and trig-
gers action on the output mode.
1. Press [Settings] key.
The R&S NGU displays the device/channel menu window.
2. Select the channel tab.
The R&S NGU displays the channel menu.
3. Select the "Output" menu item.
The R&S NGU displays the "Output" dialog.

6.2.3.1 Impedance
Output impedance is available only with R&S NGU201 model.
The output impedance function is disabled during voltage ramp time of "Ramp" func-
tion. See
