Output Termination
Applies to output amplitude and offset voltage only. The Keysight 33210A has a
fixed series output impedance of 50 ohms to the front-panel Output connector. If
the actual load impedance is different than the value specified, the displayed
amplitude and offset levels will be incorrect.

set the offset to 100 mVdc (and specify a 50-ohm load) but are terminating the
output into an open circuit, the actual offset will be 200 mVdc.

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.
