These two SCPI commands address the same instrument parameter. To be
compatible with other instrument from Keysight, both commands were
implemented. Select the desired output termination (i.e., the impedance of
the load attached to the output of the instrument). The specified value is
used for amplitude, offset, and high/low level settings. You can set the load
to any value from 0.3 to 1M. MIN selects from 0.3 MAX selects 1M.
The default is 50.
