[SOUR] :VOLT [:LEVE] [:IMM] [:AMPL] (?) <DNPD>
This command activates the generation of DC or AC voltage (depending on the DC or SIN parameter of the FUNC
command).
<DNPD>
Represents the value of DC or AC voltage expressed in Volts. Negative value is accepted for DC voltage.
“Technical Data” chapter lists the acceptable ranges.
If query is sent, M140 returns the set value of current using standard exponential format. Example: 20.547mV is
returned as -2.054700e-002. Positive numbers are not preceded with “+” sign.
[SOUR] :CURR [:LEVE] [:IMM] [:AMPL] (?) <DNPD>
This command activates the generation of DC or AC current (depending on the DC or SIN parameter of the FUNC
command).
<DNPD>
Represents the value of DC or AC current expressed in Amperes. Negative value is accepted for DC current.
“Technical Data” chapter lists the acceptable ranges.
If query is sent, M140 returns the set value of current using standard exponential format. Example: 20.547mA is
returned as -2.054700e-002. Positive numbers are not preceded with “+” sign.
[SOUR] :RES [:LEVE] [:IMM] [:AMPL] (?) <DNPD>
This command activates the generation of a resistance.
<DNPD>
Represents the value of the resistance in Ohms. “Technical Data” chapter lists the acceptable ranges.
If query is sent, M140 returns the set value of resistance using standard exponential format. Example: 20.5
is
returned as 2.001.
[SOUR] :CAP [:LEVE] [:IMM] [:AMPL] (?) <DNPD>
This command activates the generation of a capacitance.
<DNPD>
Represents the value of the capacitance in Ohms. “Technical Data” chapter lists the acceptable ranges.
If query is sent, M140 returns the set value of capacitance using standard exponential format. Example: 20.5nF is
returned as 2.050000e-008.
[SOUR] :POWE :PHAS :UNIT (?) <CPD> { DEG | COS }
This command sets the method used to specify the phase shift between the output voltage and current.
•
DEG activates a mode where all entries are done using the angle, „
“ in the range of 0.0 – 360.0
•
COS activates a mode where all entries are done using the power factor in the range of 1.000 to –1.000,
LAG or LEAD ( LAG = 0-180
, LEAD = 180-360
)
The unit of measurement remains valid even after the calibrator is switched off and back on.
If query is sent, M140 returns the set unit of measurement { DEG | COS }.
Example:
PHAS :UNIT DEG <cr> - sets the angle as the unit of measurement
PHAS :UNIT ? <cr> - the calibrator returns DEG
[SOUR] :POWE :PHAS (?) <DNPD> [ , { LEAD | LAG } ]
This command sets the phase shift between the output voltage and current. At the same time, the power generation
mode is set.
