VOLTage:OFFSet {<offset>|MINimum|MAXimum}
VOLTage:OFFSet? [MINimum|MAXimum]
Set the dc offset voltage. The default offset is 0 volts for all functions. MIN selects
the most negative dc offset voltage for the selected function and amplitude. MAX
selects the largest dc offset for the selected function and amplitude. The :OFFS?
query returns the offset voltage for the function currently selected.
– Limits Due to Amplitude: The output amplitude and offset are related to Vmax
– Limits Due to Output Termination: The offset limits are determined by the

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

reduced accordingly, and a "Settings conflict" error generated.
current output termination setting. For example, if you set the offset to 100
mVdc and then change the output termination from 50 ohms to "high
impedance", the offset voltage displayed on the function generator's
front-panel will double to 200 mVdc (and no error will be generated). If you
change from "high impedance" to 50 ohms, the displayed offset will drop in
half. See the OUTP:LOAD command on page 199 for more information.
and amplitude will be limited if the waveform data points do not span the full
range of the output DAC (Digital-to-Analog Converter). For example, the built-in
"Sinc" waveform does not use the full range of values between ±1 and
therefore its maximum offset is limited to 4.95 volts (into 50 ohms).
