The OUTPut {OFF|ON} command changes the state of the output connector by
switching the output relay. However, this command does not zero the voltage to
be output before switching the relay. Thus, the output signal may have "glitches"
for about a millisecond until the signal stabilizes. You can minimize these glitches
by first setting the amplitude to the minimum (using the VOLTage command) and
the offset to zero (using the VOLTage:OFFSet command) before changing the
output state.
OUTPut:LOAD {<ohms>|INFinity|MINimum|MAXimum}
OUTPut:LOAD? [MINimum|MAXimum]
Select the desired output termination (i.e., the impedance of the load attached to
the output of the Keysight 33210A). The specified value is used for amplitude,
offset, and high/low level settings. You can set the load to any value from 1Ω to
10 kΩ. MIN selects 1Ω. MAX selects 10 kΩ. INF sets the output termination to
"high impedance" (>10 kΩ). The default is 50Ω. The :LOAD? query returns the
current load setting in ohms or "9.9E+37" (for "high impedance").

the value specified, the displayed amplitude, offset, and high/low levels will be
incorrect.
offset, and high/low levels are 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.

Vpp. See the VOLT:UNIT command on page 201 for more information.
