DC_OFFSET
Overlapped CoupledIEEE-488 RS-232 Sequential
xx xx x
(DC Voltage Offset command) Apply a DC offset to an AC output voltage (maximum
six digits). This command applies only to single AC voltage outputs. If the selected
offset is too large for the active ac voltage range, an error message is returned.
Parameter: <value> signed offset amplitude
Example: DC_OFFSET +123.45 MV
Load a dc offset of +123.45 mV to the ac output signal.
DC_OFFSET?
Overlapped CoupledIEEE-488 RS-232 Sequential
xx xx x
(DC Voltage Offset query) Return the value of the DC offset voltage.
Response: <value> signed offset amplitude
Example: DC_OFFSET? returns +1.44E-03
Return 1.44 mV as the value of the applied dc offset. If +0.00000E+00 is returned, the
dc offset is zero.
DPF
Overlapped CoupledIEEE-488 RS-232 Sequential
xx xxx
(Displacement Power Factor command) Set the displacement power factor (phase angle)
between the 5500A Calibrator front panel terminals NORMAL and AUX (for sinewaves
output only). The NORMAL terminal output is the phase reference. The phase offset is
expressed as the cosine of the phase offset (0.000 to 1.000) and a LEAD (default) or
LAG term, which determines whether the AUX output leads or lags the NORMAL
output.
Parameters: <value>,LEAD
<value>,LAG
Example: DPF .123,LEAD
Set the current output on the 5500A Calibrator AUX terminals to lead the voltage output
on the NORMAL terminals by 82.93 degrees. (Cosine of 82.93 degrees is 0.123,
nominal.)
DPF?
Overlapped CoupledIEEE-488 RS-232 Sequential
xx xx x
(Displacement Power Factor query) Return the displacement power factor (cosine of the
phase angle) between the 5500A Calibrator front panel NORMAL and AUX terminals
for sinewave outputs.
Responses: <value>,LEAD
<value>,LAG
Example: DPF? returns 5.00E-01,LEAD
Return a leading power factor of .5 when the current output on the 5500A Calibrator
AUX terminals leads the voltage output on the NORMAL terminals by 60 degrees.
(Cosine of 60 degrees is 0.5.) The return is 0 if power factor does not apply to the output.
