Response: <value> signed offset amplitude
Example: DC_OFFSET? shows +1.44E-03
Shows 1.44 mV as the value of the applied dc offset. If +0.00000E+00 is shown, the dc
offset is zero.
DPF
Overlapped CoupledIEEE-488 RS-232 Sequential
xx xxx
(Displacement Power Factor command) Sets the displacement power factor (phase
angle) between the Calibrator front panel terminals NORMAL and AUX (for sine waves
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 tells if the AUX output leads or lags the NORMAL output.
Parameters: <value>,LEAD
<value>,LAG
Example: DPF .123,LEAD
Set the current output on the 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) Shows the displacement power factor (cosine of the
phase angle) between the Calibrator front panel NORMAL and AUX terminals for sine
wave outputs.
Responses: <value>,LEAD
<value>,LAG
Example: DPF? shows 5.00E-01,LEAD
Shows a leading power factor of .5 when the current output on the Calibrator AUX
terminals leads the voltage output on the NORMAL terminals by 60 degrees. (Cosine of
60 degrees is 0.5.) 0 shows if power factor does not apply to the output.
DUTY
Overlapped CoupledIEEE-488 RS-232 Sequential
xx xxx
(Duty Cycle command) Sets the duty cycle of the square wave output. The duty cycle is
the percentage of time the waveform is in the positive part of its cycle (1.00 to 99.00
percent). Duty cycle applies only to single-output square waves.
Parameter: <value> of duty cycle with optional PCT (percent) unit
Example: DUTY 12.34 PCT
Set the square wave duty cycle to 12.34 %.
DUTY?
Overlapped CoupledIEEE-488 RS-232 Sequential
xx xx x
(Duty Cycle query) Shows the value of the square wave output duty cycle (1.00 to
99.00).
Response: <value> of duty cycle in percent
Example: DUTY? shows 1.234E+01
Shows 12.34 % for the value of the square wave duty cycle.
