VOLTage:OFFSet
(continued)
DC Offset and Output Termination: The offset voltage is auto-
matically adjusted (and no error is generated) if you change the
output termination. For example, if you set the offset to 100 mVdc and
then change the termination from 50 ohms to “high impedance”, the
displayed offset will double to 200 mVdc. If you change fromhigh
impedance” to 50 ohms, the displayed offset will drop in half.
See the OUTP:LOAD command for more information.
For dc volts, the output level is actually controlled by setting the
offset voltage. You can set the dc voltage to any value between
5 Vdc
into 50 ohms or
10 Vdc into an open circuit.
For arbitrary waveforms, the Offset annunciator will turn on if the
waveform data has an inherent offset present (if the average is not
equal to zero). The function generator calculates the average of the
data points and compares the average to zero volts. If the average is
not within two
DAC (Digital-to-Analog Converter) counts of zero volts,
the
Offset annunciator turns on.
VOLTage:OFFSet? [MINimum|MAXimum]
Query the dc offset voltage for the currently selected function.
Returns a value in dc volts.
VOLTage:UNIT {VPP|VRMS|DBM|DEFault}
Select the output units for amplitude only (does not affect offset). When
switching from remote programming over the interface back to front-
panel (local) operation, the output units are remembered. For example,
if you selectVrms from the remote interface, the units are shown as
Vrms” on the front-panel display. The default is VPP.
[ Stored in volatile memory ]
VOLTage:UNIT?
Query the units selected. Returns “
VPP”,VRMS”, orDBM”.
