Commands
:SOURce?
Function
Queries all source settings.
Syntax
:SOURce?
:SOURce:FUNCtion
Function
Sets or queries the source function.
Syntax
:SOURce:FUNCtion {VOLTage|CURRent|
TCouple|RTD|RESistance|RJTemp}
:SOURce:FUNCtion?
VOLTage: Voltage
CURRent: Current
TCouple: Thermocouple
RTD: Resistance temperature detector
RESistance: Resistance
RJTemp: Reference junction temperature
Example
:SOURCE:FUNCTION VOLTAGE
:SOURCE:FUNCTION? -> VOLTAGE
Description If the front panel is displaying the SETUP menu,
“NONE” will be returned in response to a query.
:SOURce:LEVel
Function
Sets or queries the output setting.
Syntax
:SOURce:LEVel {<
Voltage
>|<
Current
>|
<
Temperature
>|<
Resistance
>|MINimum|
MAXimum}
<Voltage>: Voltage output setting
<Current>: Current output setting
<Temperature>: Temperature output setting
<Resistance>: Resistance output setting
MINimum: Minimum value in the selectable
range*
MAXimum: Maximum value in the selectable
range*
* See “Description.”
Example
:SOURCE:LEVEL 1V
:SOURCE:LEVEL?
-> :SOURCE:LEVEL 1.00
Description • Even if you include the plus or minus sign in
the setting, the polarity will not be set.
The polarity follows the setting specified by
the :OUTPut:POLarity command. Therefore,
the minimum and maximum values in the
selectable range of the :SOURce:LEVel are the
minimum and maximum values of the absolute
values on the polarity side specified by the
:OUTPut:POLarity command.
• To set the value with the sign, use the
:SOURce:SLEVel command.
• Before setting <Voltage>, use the
:SOURce:FUNCtion command to set the
source function to VOLTage.
Before setting <Current>, use the
:SOURce:FUNCtion command to set the
source function to CURRent.
Before setting <Temperature>, use the
:SOURce:FUNCtion command to set the
source function to TCouple or RTD.
Before setting <Resistance>, use the
:SOURce:FUNCtion command to set the
source function to RESistance.
If you set an output setting of a different source
function, a “131: Invalid suffix” error will occur.
• If the source function is RJTemp and you set
the output setting, a “221: Setting conflict” error
will occur. 9.91E+37 is returned as a response
to a query.
• The selectable range changes depending
on the range setting of the voltage, current,
or resistance or the type setting of the
thermocouple or RTD. Set the voltage, current,
or resistance range with the :SOURce:RANGe
command. Set the thermocouple or RTD type
with the :SOURce:TYPE command.
:SOURce:RANGe
Function
Sets or queries the voltage, current, or resistance
range.
Syntax
:SOURce:RANGe {<
Voltage
>|<
Current
>|
<
Resistance
>}
:SOURce:RANGe?
<Voltage>=10mV, 100mV, 1V, 10V, 30V
<Current>=1mA, 10mA, 30mA, 100mA
<Resistance>=400OHM
Example
:SOURCE:RANGE 1V
:SOURCE:RANGE?
-> :SOURCE:RANGE 1.0E+00
Description • Before setting <Voltage>, use the
:SOURce:FUNCtion command to set the
source function to VOLTage.
Before setting <Current>, use the
:SOURce:FUNCtion command to set the
source function to CURRent.
Before setting <Resistance>, use the
:SOURce:FUNCtion command to set the
source function to RESistance.
If you set range of a different source function, a
“131: Invalid suffix” error will occur.
11.4 SOURce Group
The commands in this group deal with setting the source function (voltage, current, thermocouple, RTD, resistance),
setting the output setting, setting the reference junction compensation, and creating user-defined thermocouples and
RTDs. The commands correspond to the front panel RANGE dial, TEMPERATURE dial, and output setting dials.
