4. Select the "Low Cap" or "High Cap" mode to select the capacitance mode.
● "Disabled": Capacitance mode is disabled, recommended a capacitance load
of up to 10
µ
F.
● "Low Cap": For capacitance load of up to 47
µ
F
● "High Cap": For capacitance load greater than 47
µ
F
Depending on selected mode, the R&S
NGU highlights "Low Cap" or "High Cap" in
Output auto off
Selection of "High Cap" mode without an appropriate capacitive load connected at
DUT may cause output voltage to oscillate. Then, a build in oscillation detector will trig-
ger and shuts off the output voltage.

Instrument option
R&S NGU-K104 (P/N: 3663.0390.02) option is required for digital voltmeter measure-
ments, DVM.
For better performance, connects the sense connection to the load. The sense connec-
tion is automatically used if connected. No configuration is needed.
Equipped with option R&S NGU-K104, the R&S
NGU provides an independent digital
voltmeter (DVM) to measure input voltage. See the datasheet for the full range of vol-
tages that DVM supported.
Connection for the DVM measurement is wired from the instrument rear panel.
If DVM measurement is activated, the displaying of channel output voltage is not possi-
ble. See
