VOLTage:OFFSet?
[
MINimum
|
MAXimum
]
Set the dc offset voltage. The default offset is 0 volts for all functions.
MIN selects the most negative dc offset voltage for the selected function
and amplitude. MAX selects the largest dc offset for the selected function
and amplitude. The
:OFFS?
query returns the offset voltage for the
function currently selected.
• Limits Due to Amplitude: The output amplitude and offset are related
to Vmax as shown below.
|Voffset| + Vpp ÷ 2 < Vmax
where Vmax is the maximum peak voltage for the selected output
termination (5 volts for a 50
Ω
load or 10 volts for a high-impedance
load). The new offset specified in the
VOLT:OFFS
command will be set,
but the amplitude may be reduced accordingly, and a “Settings conflict”
error generated.
• Limits Due to Output Termination: The offset limits are determined
by the current output termination setting. For example, if you set the
offset to 100 mVdc and then change the output termination from
50 ohms to “high impedance”, the offset voltage displayed on the
function generator’s front-panel will double to 200 mVdc (and no error
will be generated). If you change from “high impedance” to 50 ohms,
the displayed offset will drop in half. See the
OUTP:LOAD
command on
page 181 for more information.
• Arbitrary Waveform Limitations: For arbitrary waveforms, the
maximum offset and amplitude will be limited if the waveform data
points do not span the full range of the output DAC (Digital-to-Analog
Converter). For example, the built-in “Sinc” waveform does not use
the full range of values between ±1 and therefore its maximum offset
is limited to 4.95 volts (into 50 ohms).
