• You can also set the offset by specifying a high level and low level.
For example, if you set the high level to +2 volts and the low level to
-3 volts, the resulting amplitude is 5 Vpp (with an associated offset
voltage of -500 mV). See the
VOLT:HIGH
and
VOLT:LOW
commands
below for more information.
• To output a dc voltage level, select the dc voltage function using the
FUNC DC
command and then set the offset voltage level using the
VOLT:OFFS
command. You can set the dc level to any value between
±
5 Vdc into 50 ohms or
±
10 Vdc into an open circuit.

:LOW? [ MINimum | MAXimum ]
Set the high or low voltage levels. For all functions, the default high level
is +50 mV and the default low level is -50 mV. MIN selects the most
negative voltage level for the selected function and MAX selects the
largest voltage level. The
:HIGH?
and
:LOW?
queries return the high and
low levels, respectively.
• Limits Due to Amplitude: You can set the voltage levels to a positive
or negative value with the restrictions shown below. Vpp is the
maximum peak-to-peak amplitude for the selected output termination
(10 Vpp for a 50-ohm load or 20 Vpp for a high-impedance load).
Vhigh – Vlow < Vpp (max)
and
Vhigh, Vlow <
If the specified level is not valid, the function generator will
automatically adjust it to the maximum voltage allowed. From the
remote interface, a “Data out of range” error will be generated and
the level will be adjusted as described.
• You can set the levels to a positive or negative value, but note that
the high level must always be greater than the low level. If you
specify a low level that is greater than the high level, the function
generator will automatically set the high level to be 1 mV more than
the new low level. A “Settings conflict” error will be generated.
