Output Configuration Commands
4
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.

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 1
Ω
to 10 k
Ω
. MIN selects 1
Ω
. MAX selects 10 k
Ω
.
INF sets the output termination to “high impedance” (>10 k
Ω)
. The
default is 50
Ω
. The
:LOAD?
query returns the current load setting in
ohms or “9.9E+37” (for “high impedance”).
• 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, offset, and high/low levels will be incorrect.
• If you change the output termination setting, the displayed output
amplitude, 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.
• You cannot specify the output amplitude in dBm if the output
termination is currently set to “high impedance”. The units are
automatically converted to Vpp. See the
VOLT:UNIT
command on
page 183 for more information.
