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.
• Output termination: 1
Ω
to 10 k
Ω
, or Infinite. The default is 50
Ω
. The
message line at the top of the display calls attention to output
termination settings other than 50
Ω
.
• The output termination setting is stored in non-volatile memory
and does not change when power has been off or after a remote
interface reset (assuming the Power On state is set to “default”).
• If you specify a 50-ohm termination but are actually terminating into
an open circuit, the actual output will be twice the value specified.
For example, if you 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.
• If you change the output termination setting, the displayed output
amplitude and offset levels are automatically adjusted (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.
• Front-Panel Operation: Press
and select the
Output Setup
softkey. Then use the knob or numeric keypad to select the desired
load impedance or press the
Load
softkey again to choose “High Z”.
• Remote Interface Operation:
