"MINimum", "MAXimum", or "DEFault" in place of a specific value for the
parameter. MIN selects the most negative dc offset voltage for the function
and amplitude specified. MAX selects the largest dc offset for the function and
amplitude specified. The default offset is 0 volts for all functions.

output termination (5 volts for a 50Ω load or 10 volts for a high-impedance
load).

If the specified offset voltage is not valid, the function generator will
automatically adjust it to the maximum dc voltage allowed with the amplitude
specified. From the remote interface, a "Data out of range" error will be
generated and the offset will be adjusted as described.
current output termination setting (the APPLy command does not change the
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). The "0"
DAC value is still used as the offset reference even if the waveform data points
do not span the full range of the output DAC.
