VOLTage {<amplitude>|MINimum|MAXimum}
VOLTage? [MINimum|MAXimum]
Set the output amplitude. The default amplitude is 100 mVpp (into 50Ω) for all
functions. MIN selects the smallest amplitude (10 mVpp into 50Ω). MAX selects
the largest amplitude for the selected function (at most 10 Vpp into 50Ω
depending on the selected function and offset voltage). The VOLT? query returns
the output amplitude for the function currently selected. Values are always
returned in the units set by the most recent VOLT:UNIT command.

where Vmax is the maximum peak voltage for the selected output termination

amplitude specified in the VOLT command will be set, but the offset voltage
may be reduced accordingly, and a "Settings conflict" error generated.
setting, the displayed output amplitude will be automatically adjusted (and no
error will be generated). For example, if you set the amplitude to 10 Vpp and
then change the output termination from 50 ohms to "high impedance", the
amplitude displayed on the function generator's front-panel will double to 20
Vpp. If you change from "high impedance" to 50 ohms, the displayed
amplitude will drop in half. For more information, see the OUTP:LOAD
command on page 199.
